Here are some tips for learning mandarin

Tip 1. Find out the corresponding rules in Mandarin and their dialects, and enhance the memory.
The difference between various dialects and Mandarin Chinese language is mainly phonetics, with little difference in vocabulary and grammar. The main differences in phonetics are as follows: in most areas blade-alveolars are used the same as retroflex; so do n and l; many vowels like eng、ing、e、uo are ignored; the rounded lips of vowels for most people are not enough. Combining these characteristics, students can find the corresponding rules of dialects and Putonghua, and thus practice and memorize the difficulties.

Tip 2. Try to achieve a full breath and clear pronunciations.
That is to say, read the consonant, vowel and tone of every character loudly, in particular, the vowel. Don't be vague. The vowel head, body and tail should be read clearly. For example, the pronunciation of xiang(响) should be “x-i-ǎ-ng”(consonant-vowel head-body-tail) rather than “x--ng ”(consonant-vowel head-tail).

Tip 3 .Pay attention to the pronunciation of the neutral-tone words.
In addition to the required words, many function words also read softly, such as structure auxiliary(de的, de地, de得), dynamic auxiliary(zhe着, le了, guo过) , directional verb(lai来, qu去) and plurality(men们).

Tip 4. When reading an article, be sure to express the emotion of the article correctly.
Pay attention to the stop, stress, tone and rhythm. In a word, where should we stop and how long; where is the stress and where should be light; which sentences should be connected in one paragraph and which not and which is the key point; is the voice of the whole sentence ascending or descending, strong or weak, quick or slow? All of these should be relished and practiced a lot.

1. Stimulate Students' Interest in Learning Chinese Characters
   
   When students do not understand the relationship between the glyphs and phonograms of Chinese characters as well as the origin of Chinese ideograms. They feel that Chinese characters are difficult to learn. Under such fears, it is difficult to have an interest in Chinese characters. In the early stage of Chinese character teaching, we must stimulate students' interest in learning Chinese characters and help them overcome this fear. Only in this way can Chinese teaching be carried out smoothly.

There are two ways to stimulate students' interest in learning and overcome the fear of difficulty. The first is to introduce the origin of Chinese characters, and let students understand how Chinese characters evolved to what they are today. How did the original shape of Chinese characters come from? And how does it express the meaning? In the process of introducing the evolution of Chinese characters, students are also allowed to understand the ideographic functions of Chinese characters, especially the pictographic and ideographic characters and the shape of the sound words. The second method is to introduce the relationship between glyphs and words, glyphs and meanings so that students can understand the relationship between sound and meaning, eliminate the fear of difficulty, and provide more clues for the memory of Chinese characters.

Introduce the origin of Chinese characters. There are 7 kinds of sayings about the formation of Chinese characters. Among them, pictographs express meaning most directly. Introducing the origin of Chinese characters from hieroglyphics is easier for students to accept and understand. The specific operation is as follows: Give the students a few Oracle characters that they have already learned, and let the students guess what the words are. Students will make all kinds of guesses. Of course, it is very likely that they will not be guessed correctly. It doesn't matter. After students have used their imagination, teachers can tell them what the words are. Most of the Chinese characters have changed a lot, and very different from the current simplified characters. Comparing the original Oracle with the simplified characters often arouses the students' surprise. The students will feel very strange and very interesting. At this moment, the teacher should give them a history of the development of this Chinese character, and let the students understand how it evolved into what it is today.

For example, write the oracle of the horse on the blackboard and ask the students to guess what does it mean, then tell the students the answer. The students will find that the two "horse" characters are very different, then the teacher will show the students how the word "horse" gradually evolved from the pictogram to the current glyph.

2. Resolutely Implement The Component Teaching Method

Component teaching is an effective teaching method. It can help students understand the relationship between various parts of Chinese characters, and can also reduce the number of things students need to remember. In the study of psychology, people's cognition of Chinese characters has both first whole then part processing and first part then whole processing. These two processing methods can be flexibly utilized according to the relationship between the whole and parts, parts and parts of different Chinese characters. As mentioned above, the relationship between the whole and parts, parts and parts will affect the learning of Chinese characters. The part mentioned here refers to components rather than strokes. In the component teaching, it is not only to let students understand the relationship between the whole and part, part and part, but also to improve the students' familiarity (or sensitivity) with specific exercises. This level of familiarity can improve the speed of recognizing Chinese characters, as well as enhance memory.

Now, for us, there is no need to emphasize the advantages and importance of the component teaching method. What we need to focus on is how to truly adhere to the component teaching and improve students' familiarity with the relationship between Chinese characters and components, components and components. I think there are two exercises that can achieve this goal: one is the Chinese character split practice, and the other is the Chinese character combination exercise.

The curing temperature of various curing agents including epoxy curing agent is different, and the heat resistance of curing products is also very different. Generally speaking, the curing agent with high curing temperature can be used to obtain the cured product with excellent heat resistance. For addition polymerized curing agents, the curing temperature and heat resistance are increased in the following order: aliphatic polyamines & lt; alicyclic polyamines & lt; aromatic polyamines ≈ phenolic & lt; anhydrides.

The heat resistance of the curing agent is at the level of aromatic polyamine. The heat resistance of anionic polymerization type (tertiary amine and imidazole compounds) and cationic polymerization type (BF3 complex) are basically the same, which is mainly due to the different initial reaction mechanism, but eventually form the ether bond network structure.

The curing reaction belongs to the chemical reaction, which is greatly influenced by the curing temperature, the temperature is increased, the reaction speed is accelerated, the gel time is shorter, the gelation time decreases linearly with the increase of curing temperature, but the curing temperature is too high, which often degrades the curing property, so there is the upper limit of curing temperature. As a suitable curing temperature.

According to the curing temperature, the curing agents can be divided into four categories: the curing temperature of low temperature curing agent is below room temperature; the curing temperature of room temperature curing agent is between room temperature and 50 ℃; the curing temperature of medium temperature curing agent is between 50 ℃ and 100 ℃; the curing temperature of high temperature curing agent is above 100 ℃. There are few kinds of curing agents belonging to low-temperature curing type, such as polyisocyanate type and polyrylcohol type. T-31 modified amines and yh-82 modified amines developed and put into production in China can be cured below 0 ℃. There are many kinds of room temperature curing: aliphatic polyamines, alicyclic polyamines, low molecular polyamides and modified aromatic amines. Some aliphatic polyamines, tertiary amines, mimidazoles and boron trifluoride complexes belong to the medium temperature curing type. The high temperature curing agents include aromatic polyamines, anhydrides, phenolic resins, amino resins, dicyandiamide and hydrazide.

For high temperature curing system, the curing temperature is generally divided into two stages. The gel is solidified at low temperature before reaching the gel state or slightly higher than the gel state. Then the post-cure is solidified at high temperature and solidified as pre curing (pre-cure).

The curing agent of epoxy resin must react with curing agent to form three-dimensional structure. Therefore, the structure and quality of curing agent will directly affect the application effect of epoxy resin. In foreign countries, the research and development of curing agent is far more active than that of epoxy resin. Compared with the variety of epoxy resin, the curing agent has more varieties and strong confidentiality. Every time a new curing agent is developed, one aspect of the problem can be solved, which is equivalent to developing a new epoxy resin or opening up a new application of epoxy resin. It can be seen that the development of new curing agent is far more important than the development of new epoxy resin.

Many pet owners or related practitioners may have questions like this:

"Since you can clone dogs and cats, it should be easy to clone other animals, right?"

"Why not clone more kinds of animals, such as birds, rabbits, and pigs?"

"Isn't your animal cloning biotechnology very mature? But why do you deliver in 6 to 10 months? Can it be faster? " and so on.

In fact, although cloning biotechnology has been conquered and mastered by many biologists, each species has its own characteristics of reproductive physiology. One of the main difficulties in animal cloning process is how to obtain mature oocytes and reconstruct embryos. Oocyte is one of the essential elements in cloning practice. Take dog cloning as an example. Dogs have special reproductive physiological structure, so hormone regulation has no effect. It is difficult to accurately determine the maturation time of oocytes and obtain oocytes.

At the same time, dogs have higher fat content in oocyte, which is sensitive to the external environment and requires a high level of in vitro operation technology. It is difficult to clone pet dog because of the difficulty of multiple technical processes. As for the cloned cat, there are also technical difficulties in how to construct a complete reconstructed embryo. Meanwhile, the apoptosis rate of the cat is relatively faster. When the body cells are sampled from the skin, the requirements for the tissue are higher. Skin tissues that have died more than 3 days have a lower success rate in establishing cell lines. In addition, Cats are animals that stimulate ovulation. Obtaining oocytes has its own difficulties.

Therefore, each kind of animal has its own technical difficulties. There is no same technical operation template to apply. If we want to develop a new animal cloning plate, we need to reinvest technical force to conquer it, which must take a long time. It also explains why it takes a certain period to deliver whether it's a cloned cat or a cloned dog. Oocytes are not acquired by acquisition. It depends on the law of reproduction and development of animals, which requires careful reserve and observation.

In addition, the cloned animals of Sinogene will not be delivered to pet owners until they grow up safely in the laboratory for two months. And the first vaccination will be made to ensure that the delivered cloned babies are healthy and immune. Therefore, choosing pet cloning service from Sinogene is also a choice of rest assured and intimate, so that your pets can accompany you forever.

A restaurant is a public space, containing kitchen area, dining area and toilet. The temperature differs from room to room, and peoples feeling and requirement of climate control also diversified. It is a challenge to meet these different demands only using air conditioning. Traditional air conditioning will automatically turn off when reaches set temperature. In this case, there was no control of humidity or part of control when the air conditioning works.

PROBLEM MY FACE WITHOUT HUMIDITY REGULATION

• Diffusers dripping water
• Condensation on glass doors and windows
• Floors that sweat or take a long time to dry after mopping
• Mold and fungus lead Hygiene problem
• Uncomfortable environment for customers and staff members

Whenever we find ourselves in public places, crowded or not, the warm temperature combined with excessive air moisture is extremely uncomfortable. A most efficiency and economical option to control humidity is to install a piece of equipment dedicated to dehumidifying the outdoor air.

The kitchen dehumidifier works in conjunction with air conditioner. The dehumidification equipment controls humidity via a space humidistat while the AC unit controls space temperature via a space thermostat. And we also provide humidifier unit, consisting of heating, cooling and humidity control, which is also can be customized.

The following methods may let you know how to learn Chinese words fast.
1. Read first, then write. The relationship between the component structure and morphological feature of Chinese characters are obvious, so Chinese characters are easy to read, but their writing is difficult for foreign students. We can first let the students feel the glyph, understand the meaning of character, remember the pronunciation, but reduce the requirements of writing. Read first, then write; read more, write less.

2. Stroke decomposition. Correctly decomposing the Chinese characters into strokes, especially synthetic strokes, which helps write and retrieve Chinese characters.

3. 
   Literacy card. There are various literacy cards on the market, you can also make it yourself. It is better to write the Chinese character on the front side and pinyin or paraphrase on the back side. There are many ways to use character cards, such as guessing pronunciation, meaning, and connection while looking the Chinese characters on the back side. It can be used either by oneself or by two people.
   
   4. Part combination. Teachers of Chinese as a foreign language can provide a set of parts, such as "口,十,又,土,女", requiring students to form more than ten Chinese characters.
   
   5. Component construction. Teachers of Chinese as a foreign language can give students a component, such as "扌" or phonetic element, "令", asking students to write characters as much as possible with these components.
   
   6. Dictation. This is one of the most commonly used methods to test students' mastery of Chinese characters, but it is not suitable to be used as the only or main method, because the learners using the phonetic alphabet as their mother languages are difficult to associate the Chinese character pattern with the sound in the short term.
   
   7. Rule discovery. By selecting some typical phonetic characters, the teachers can guide the students to discover the rules of phonetic symbols and components to memorize Chinese characters. For example, we can let the students find the differences between "请,情,清,晴", and then explain their meanings.

For a foreign learner, the instructor should be able to use a wonderful lead to stimulate student interest. A good introduction to the new lessons, like a bridge, links old and new lessons. Teachers should carefully design the lead words, use the students' curiosity, seek new psychology, and give students a surprise, which will induce students' interest in learning and enlighten students' thinking. In the process of Chinese teaching, you can intersperse the interesting things of some scientists or writers, and use the methods of induction, directness, doubt, performance, storytelling, discussion, etc. to mobilize the enthusiasm of students to learn, so that they will change from passive learning to active learning, The level of Chinese learning will continue to be increased. Its creation environment enables students to experience the joy of learning. For example, when it comes to price, the teacher can create a supermarket environment, let students experience the fun of learning by buying different things, so that the Chinese classroom won’t be boring, the students will have a deep memory, and the learning effect will be greatly improved. It is much better than just reading a textbook.

In addition, role-playing methods can be used. Interesting games can create a relaxed teaching environment for students to master Chinese listening, speaking, reading and writing without knowing it. Then mobilize the students' emotions. As an old saying goes, love is the most touching thing in one's heart. The teacher's teaching process is the process of imparting knowledge, and it is the process of emotional communication between teachers and students. In basic chinese course, teachers should guide students to enter the scene to experience certain emotions and use their rich expression and vivid language to stimulate their enthusiasm for learning, make them learn Chinese in happiness.

The good way to learn to speak mandarin fast is of course more than these. These are just to make foreigners interested in Chinese. If you are interested in one thing, no matter who you are, you may spend more time and energy on this matter, and you will enjoy it. Among them, interest is the best teacher. So the best way to learn Chinese is to immerse yourself. Only by immersing yourself in a specific environment can you have unexpected effects.

Epoxy resin curing agent is an additive that reacts with epoxy resin to form a reticular three-dimensional polymer, envelops composite material in a reticular body, and makes the linear resin into a tough solid.

1. classification
2. Basic

Basic curing agent WTF: including aliphatic diamines, polyamines, aromatic polyamines, other nitrogen compounds and modified aliphatic amines.

2. Acids

Acid curing agents: including organic acids, acid anhydride curing agent, boron trifluoride and its complexes.

3. Addition type

Addition curing agent: this type of curing agent undergoes an addition reaction with an epoxy group to form a part of the segment of the cured product, and through a stepwise polymerization reaction, the linear molecules are cross-linked to form a body structure molecule. This type of curing agent is also called melon-type curing agent.

4. Catalytic type

Catalytic curing agent: this kind of curing agent only initiates the epoxy resin. After opening the epoxy group, it catalyzes the polymerization of the epoxy resin into a network structure to form a homopolymer with an ether bond as the main structure.

5. Explicit type

Explicit curing agent is a common curing agent, which can be divided into addition polymerization type and catalytic type. The so-called addition polymerization type is to open an epoxy ring to perform an addition polymerization reaction, and the curing agent itself participates in a three-dimensional network structure. If such kind of curing agent is added in a small amount, the cured product is connected to an unreacted epoxy group. Therefore, there is a suitable amount for this type of curing agent. Catalytic curing agents use cationic or anionic methods to ring-open addition polymerization of epoxy groups. In the end, curing agents do not participate in the network structure, so there is no suitable amount of equivalent reaction. However, increasing the amount will speed up the cure. Among the explicit curing agents, varieties such as dicyandiamide and adipic acid dihydrazide are insoluble in epoxy resin at room temperature, but begin to cure after dissolution at high temperature, so they also show a latent state. Therefore, it can be called a functional latent curing agent.

In the history of human development, there are many traces of the participation of animals. They have played important roles in human history.

In modern times, science and technology have replaced many functions once realized by animals, making the original role of animals in human life less important. However, another role is becoming more and more important, that is, the company to human beings.

So we are called "the companion animals".

We always have different "selfishness" when we let animals into our lives, for their cuteness, or they make us look cool.

It's not easy to take care of animals, but people always enjoy it. Because when we get along with animals, we can always be touched by their loveliness. We use the words "so cute", "so wonderful" to describe them.

However, there is reunion and separation, and the life span of animals is only 10-20 years. When they leave, many people will be heartbroken. With the development of animal cloning technology, your pet can accompany you for a longer time.

In recent years, psychological development has defined a psychological disease - "pet loss". According to statistics, 60% of pet owners will have such a stage after their companion animals die. Their greatest hope is to have them back.

Pets are just as reluctant to be separated from us:

You may have been moved by the story of "Hachi: A Dog's Tale". There's a lot more to it besides dogs.

There is an orange cat called Kapas in England. It has been waiting for the same bus for consecutively for five years. Its owner used to take it on this bus. Later, the owner died unexpectedly, and the cat began to take the bus alone. Maybe it felt that one day it could meet the familiar figure here again.

Tani, the tabby cat, followed the ambulance to the hospital. It didn't know that his owner had passed away and was waiting at the door of the hospital day by day.

In Brazil, after the owner of a white horse, Sereno, died, his horse wept at the scene of the funeral.

Sinogene, a team of young people, relies on powerful and cutting-edge life science and animal cloning biotechnology to realize commercial animal pet cloning of dogs, cats, and horses by means of cloning and using companion animal cells. Our companion animals return to their owners through their own body cells.

When Mr. Huang, the owner of Garlic, the first cloned cat in China, first saw a kitten cloned with Garlic's body cells, he said, "the first time I saw it, I knew it was my Garlic". These words moved the Sinogene people in the Sinogene Biotechnology, and they also felt that they were doing very valuable work.

It's spring and summer. The air is sweet. What color bridesmaid dress should we choose to attend the wedding? It can neither be too dazzling, overwhelming the bride's style, nor too dull, not in line with the theme of spring and summer. At the same time, we should also consider the wedding theme, venue bridesmaids, personality temperament. Are the fairies having a headache about it? Today, I will analyze the popular colors of spring and summer for fairies and choose the right bridesmaid dress to make your wedding more splendid. We have bright purple bridesmaid dresses, bright red bridesmaid dresses, slate blue bridesmaid dresses, etc. for sale.

As long as fairies remember the three principles of selecting bridesmaid dress, it is easy to find the color of bridesmaid dress suitable for spring and summer weddings.

1. The color of bridesmaid dress should correspond to or complement the main tone of the wedding.

This is the most important principle to choose the color of bridesmaid dress. The keynote of spring and summer weddings is mostly light and beautiful. Therefore, gentle and elegant or lively colors are good choices. Usually a wedding will use two or three tones, one of which will be the main color. The remaining complementary colors will complement and enrich the wedding color. For example, in a pink, white and gold wedding, pink is the main color, and white and gold is the auxiliary color. The easiest way to choose the color of bridesmaid dress is to echo the main color. After taking a picture, it will also be very harmonious from the perspective of color.

1. The color of bridesmaid dress should correspond to the wedding venue.

Spring and summer festivals are especially suitable for outdoor weddings. Bridesmaid dress can be chosen in small, fresh colors with low saturation, such as light cornel powder, island paradise blue and vegetation green. These colors can be matched with outdoor flowers and plants, and it is super-matching. You can also choose all colors with high saturation, such as feather cabbage green and primrose yellow. Like sunshine and blue sky, it is fierce and unrestrained.

III . The color of bridesmaid dress should correspond to the temperament of the bride.

You may find it a little strange. Is the bridesmaid dress not worn on the bridesmaid? What does it have to do with the bride? However, there will be many pictures of brides and bridesmaids. In choosing the color of bridesmaid dress, it is necessary to highlight and set off the bride's temperament. For example, you are clearly a little princess, but you choose the color of dark Gothic system as bridesmaid dress. It seems very incompatible for bridesmaids to stand beside you. You are a queen, but you choose the naive blue pink as bridesmaid dress. It looks awkward. Of course, besides the three most important elements, you should also consider the color and temperament of the bridesmaid, but in the final analysis,

everything should highlight the beauty of the bride.

Many brides preparing for a Chinese wedding have a headache about how to solve the bridesmaid dress. It should not only conform to the Chinese tradition, but also make girlfriends beautiful. Is it possible? Of course. There are so many perfect Chinese bridesmaid dresses.

I. Cheongsam

Cheongsam originates from the traditional clothing of Manchu female. After Republican China, it was improved based on this traditional clothing by Han female in Shanghai and Peiping. The improved cheongsam is tailored close to the body, showing the concave and convex feeling of women. It is dignified and elegant. Because it rose after the Republic of China, it is suitable to be used as bridesmaid dress for new Chinese wedding.

II. Xiaofengxian

"Xiaofengxian Dress" is also a kind of cheongsam, which evolved from the long gown of Manchu women in Qing Dynasty. It has a close waist and fashionable tailoring. The biggest feature is the vertical collar.

III. Xiuhe dress

Xiuhe dress is a kind of dragon and Phoenix coat. It is more gorgeous, so many brides will be used as wedding dresses. It is also great to choose simple and elegant style as bridesmaid dress.

IV. Hanfu

Generally speaking, as long as it is Han marriage, whether it is Zhou or Tang Han marriage, bridesmaids should wear Hanfu to meet the theme of the whole wedding.

In addition, We have tangerine bridesmaid dresses, purple satin bridesmaid dresses, cinnamon rose bridesmaid dresses fo sale.

WHY ICE RINKS NEED DEHUMIDIFIERS

Ice rinks and curling make the indoor room in a relative low temperature. Humidity enters with the frequent opening and closing doors, the incoming warm air. If not control the humidity in the indoor ice rinks and curling, condensation forms, usually in the ceiling. 

With excessive moisture, many problems will occur: drops of condensation dripping down to the rink surface, puddles on the ice, vision-obscuring fog and soft ice. These problems will definitely pose a dangerous threat to skaters inside and lead to unpleasant experience to the customers. So controlling the humidity at ice rinks is necessity and highly recommended.

Greeme's indoor ice arena dehumidification systems have high performance, which remove large amounts of moisture from the air, ensuring fog-free conditions year around.

Here are some suggestions about how to learn chinese fast and easy for foreigners.

1. 
   Learn some basic vocabulary. When you learn a language, the first thing to do is to memorize some simple and important words and start practicing as much as you can. Although grammar and sentence structure are also important, it is meaningless to learn them before you have mastered a certain vocabulary.
   
   2. Learn some basic phrases. Once you have mastered some vocabulary, you can try to learn basic phrases and sentences, which can help you with your daily conversation.
   
   3. Learn the tones. Chinese is a tonal language, the same words with different tones have a different meaning (even if the spelling and pronunciation are the same). This may be difficult for people who are accustomed to speaking English, but if you want to speak Chinese well, the tone is crucial.
   
   4. Learn pronunciation. By listening to native speakers (or YouTube), you can learn the correct pronunciation, and after you practice it, you need to apply what you have learned to specific words.

After using different tones, the same words can have different meanings. For example, the tones "mā"and" má"are just like "I want cake" and "I want coke", they have totally different connotation.

Therefore, when learning a word, it is not enough to only learn pronunciation, but also to learn the correct tone, otherwise, the words can easily be used in the wrong context, making it difficult for others to understand what you are trying to express.

The best way to learn pronunciation is to speak Chinese with the locals. When you pronounce it correctly, he can give you encouragement; when you are wrong, he can help you learn the correct pronunciation. KCEL provide best chinese language course for beginners who want to grasp Chinese fast and easily.

5. Learn grammar and sentence structure. There is a common prejudice that Chinese is a language without grammar. In fact, the Chinese grammar system is very complicated, which is very different from English and other European languages.

Fortunately, in learning Chinese, we can learn without memorizing verbs, consistency, speech, plural, tense, etc., because the analyzability of Chinese makes these things simple and intuitive.

Another advantage is that the sentence structure in Chinese is similar compared with English, that is, the subject-verb-object structure, which makes the translation from English to Chinese and Chinese to English more simple. For example, in English, "he likes cats" is translated into Chinese as "ta(他) xi（喜） huan（欢） mao（猫）".

Of course, Chinese also has a few sentence structures that are different from English, which may make it difficult for native English speakers to master, such as classification, prominence, preference and so on. But before learning basic Chinese, there is no need to worry.

When it is heard that Paul’s mystery gospel includes the death, burial, and resurrection of Jesus Christ some properly identify the teaching of the cross before Paul by Jesus and Peter.

However, when we look closely at how the cross is foretold we see that there are different ways to talk about the cross. While there is a teaching of the cross according to prophecy, it is Paul that reveals the preaching of the cross according to the revelation of the myster

Jesus Teaches the Cross

During his ministry to Israel, Jesus told his disciples about what the prophets had said concerning him: that he would be put to death and raise again the third day (Luke 18:31-34).

After overthrowing the tables in the temple he declared publicly:

“Destroy this temple, and in three days I will raise it up.” – John2 :19

When requested for a sign he said that “an evil and adulterous generation seeketh after a sign”, but the sign he gave them was his resurrection after three days (Mat 12:39-40).

Clearly Jesus told of his death and resurrection during his earthly ministry. However, it is important to recognize that while he mentioned the cross nobody understood it.

“And they understood none of these things: and this saying was hid from them, neither knew they the things which were spoken.” – Luke 18:34
When he mentioned the raising of his “temple” in three days, not even his disciples understood what he meant until after it had happened (John 2:20-22).

Everytime Jesus spoke plainly about his death it was privately to his disciples and was not preached publicly as the gospel of salvation:

“From that time forth began Jesus to shew unto his disciples…” – Mat 16:21
“Then he took unto him the twelve, and said unto them…” – Luke 18:31
Jesus presented his death to his disciples as a fulfillment of the prophets, and his resurrection to the nation as a sign. Although Jesus talked about the cross, he did not speak about the hidden wisdom in the cross that he would later reveal to Paul (1 Cor 2:6-8).

Peter Preaches the Cross

After the resurrection Peter knew about the cross and even preached it at Pentecost. However, he did not preach the cross in a mystery, but the cross as it related to prophecy.

As Jesus before him, Peter taught the death of Christ as a fulfillment of prophecy:

“But those things, which God before had shewed by the mouth of all his prophets, that Christ should suffer, he hath so fulfilled.” – Acts 3:18
Since Jesus of Nazareth fulfilled the prophecies, this was proof that he was the Messiah. In speaking of his resurrection Peter quotes the prophet David:

“Therefore being a prophet, and knowing that God had sworn with an oath to him, that of the fruit of his loins, according to the flesh, he would raise up Christ to sit on his throne; He seeing this before spake of the resurrection of Christ, that his soul was not left in hell, neither his flesh did see corruption.” – Acts 2:30-31 (regarding Psalm 16:10)

Peter spoke of the cross as a fulfillment of prophecy, and yet he also preached the cross as a shame to Israel, since they purposely killed the Prince of Life:

“Him… ye have taken, and by wicked hands have crucified and slain:” – Acts 2:23
“But ye denied the Holy One and the Just, and desired a murderer to be granted unto you; And killed the Prince of life, whom God hath raised from the dead; whereof we are witnesses.” – Acts 3:14-15
Since Israel had killed their Messiah, the resurrection of Christ was necessary according to prophecy for him to sit on David’s throne and to bring in the kingdom. No king, no kingdom.

So, Peter taught the death of Christ as a shame and a fulfillment of prophecy, and the resurrection as a necessity for the kingdom to come (Acts 2:33; Acts 3:19-21; 1 Pet 1:3).

Paul’s Preaching of the Cross

So far, the preaching of the cross has been seen to be merely a fulfillment of the prophecies and necessary for the kingdom come to Israel. The death was even presented as bad news to the disciples, and a shame to Israel.

In contrast to this teaching of the cross, the Lord revealed to Paul a mystery preaching of the cross. This mystery is the glorying of that which was previously shameful (Gal 6:14). It revealed a hidden purpose to the teaching of the cross that was according to prophecy.

Paul preached the cross as good news to all men for their salvation. With Paul the preaching of the cross has changed from being taught privately to a worldwide message, not of shame, but of rejoicing.

To Paul the cross was not merely the death of the Messiah, but was our death in Him.

“Knowing this, that our old man is crucified with him, that the body of sin might be destroyed…” – Rom 6:6
“I am crucified with Christ:…” – Gal 2:20

“God forbid that I should glory, save in the cross of our Lord Jesus Christ, by whom the world is crucified unto me, and I unto the world.” – Gal 6:14
The resurrection was how sinners could receive eternal life through free justification:

“…and was raised again for our justification.” – Rom 4:25
Because Christ rose from the dead, we have a position in heavenly places in Him (Eph 1:3, Col 3:1).

Christ’s resurrection was not needed merely for an earthly kingdom, but to reconcile all things to himself which included heaven and earth (Eph 1:18-22).

It was for this reason that Paul can confidently declare:

“Remember that Jesus Christ of the seed of David was raised from the dead according to my gospel:” – 2 Tim 2:8
Peter taught Jesus Christ’s resurrection as the seed of David to sit on David’s throne. Paul taught Christ’s resurrection to be the head over all things: heaven and earth. What a more excellent teaching and reason for Christ to resurrect, and it can only be understood in light of the heavenly mystery of Christ.

Conclusion

The cross of Christ according to prophecy was one more event needed in the fulfillment of God’s promises to the nation Israel to have dominion on the earth. It was all searchable in the prophets (John 5:29, Luke 24:44, Acts 3:18).

What was kept secret was the preaching of the cross as the gospel that freely saves all men. The cross of Christ according to the mystery is the channel of God’s unsearchable riches of grace:

“That in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth; even in him:” – Eph 1:10

6. Latent type

Latent Epoxy curing agent refers to relatively long-term stability at room temperature after mixing with epoxy resin (epoxy resin generally requires more than 3 months to have greater practical value, and the most ideal requires more than half a year or more than 1 year ), and only needs to be exposed to heat, light, moisture and other conditions to start the curing reaction. This type of curing agent is basically a physical and chemical method to block the curing agent activity. Therefore, in some books, these varieties are also classified as latent curing agents, which can actually be called functional latent curing agents. Because the latent curing agent can be mixed with epoxy resin to make a one-liquid complex, simplifying the application procedures of epoxy resin. Its applications range from single-pack adhesives to coatings, dipping varnishes, potting compounds, powder coatings, and more. Latent curing agents have attracted increasing attention abroad, and can be said to be a key subject for research and development. New varieties of curing agents and new technologies have emerged endlessly and actively.

7. Amine curing agent

The curing effect of the primary and secondary amines on the epoxy resin is that the active hydrogen on the nitrogen atom opens the epoxy group, so that it is crosslinked and cured. Aliphatic polyamines such as ethylenediamine, hexamethylenediamine, diethylenetriamine, triethylenetetramine, diethylaminopropylamine, etc. have greater activity and can cross-link and cure epoxy resins at room temperature. While aromatic polyamines have low activity, such as m-phenylenediamine, which can only be fully cured at 150℃.

8. Anhydride curing agent

Dibasic acids and their anhydrides such as maleic anhydride and phthalic anhydride can cure epoxy resins, but they must be baked at higher temperatures to cure completely. The acid anhydride first reacts with the hydroxyl group in the epoxy resin to form a monoester, and the carboxyl group in the monoester undergoes addition esterification with an epoxy group to form a diester.

9. Synthetic resin curing agent

The low molecular weight polyamide resin is a kind of amber-colored viscous resin formed by the reaction of linoleic acid dimer or tungoleic acid dimer with aliphatic polyamines such as ethylenediamine and diethylenetriamine.

10. Latent curing agent

This curing agent is stable under normal conditions, but when it is heated to a certain temperature, it shows its activity to cure the epoxy resin. Such as dicyandiamide, mixed with epoxy resin, is stable at room temperature. If the temperature is 145-165℃, the epoxy resin can be cured within 30 minutes. Boron trinitride ethylamine complex is also stable at room temperature, but can cure epoxy resins above 100℃.
