With the advancement of technology, the development of plastic medicine bottles has also received more and more attention. The quality of pharmaceutical packaging has a certain influence on the safety of medicines and the prevention of moisture in medicines. Rolling bottles face the ever-increasing market competition with traditional old-fashioned glass bottles or some opaque oral medicine bottles.

It cannot meet the needs of people. Even some old-fashioned glass packaging medicine bottles, because of its poor technology, will drop a part of the glass powder into the bottle, making the medicine into a drug, which is neither hygienic nor safe. The appearance of plastic bottles broke the routine of packaging products.

The material of the bottle has changed, which changes the mode of the package. The production of plastic packaging bottles requires high-temperature sterilization. During the process of stretching, blow molding and forming, the microcrystalline orientation plane in the plastic can improve the strength, hardness, and transparency of the plastic packaging bottle through changes in its basic structure. A new generation of packaging that is trend-setting shows the unification of aesthetics and practicality. With the continuous innovation and development of new products for moisture-proof barrels and the strong investment and development of pharmaceutical packaging in China, it is believed that the future of Chinese medicine bottle market is definitely worthy of attention, and it is also promising.

At present, there are three kinds of projection technology: CRT, LCD, and DLP.

CRT projector is the earliest projection technology, which is similar to the CRT display. It has the advantages of long life, rich color display, good reducibility, and rich ability to adjust geometric distortion. Due to technical constraints, it is impossible to improve the resolution and lumen at the same time. Therefore, CRT projectors have been phased out at this stage.

The technology of LCD projector is transmission projection technology, which is the most mature at present. The color of the projection screen is restored to be true and bright. With high color saturation and high light utilization efficiency, an LCD projector has a higher brightness output. At present, the LCD projector is the main projector with a high lumen in the market. Its disadvantage is that the black layer is not very good. LCD projection technology is divided into LCD and 3LCD. The difference between them lies in the color restoration degree and picture quality.

DLP reflective projection technology. The gray level and signal-noise ratio of DLP projector image are greatly improved, and the image quality is fine and stable. In particular, when playing dynamic video, the image is more smooth, without pixel structure sense, the image is natural, and the digital image restoration is true and accurate. The advantage of DLP compared with 3lcd is that there is no crosstalk between grayscale and 3D.

Of course, there is also LCOS projection technology, which is a new projection technology. Because the cost is too high, it is seldom used

Projector contrast

Contrast is the ratio of black to white, that is, the gradient level from black to white. The larger the ratio, the more gradients from black to white, and the richer the color representation. Contrast is very important to the visual effect. Generally speaking, the larger the contrast is the clearer the image is, and the brighter the color is. However, if the contrast is small, the whole picture will be gray. High contrast is very helpful for the clarity, detail, and gray level of the image. High contrast has advantages in black-and-white contrast, clarity, integrity, and so on. Relatively speaking, in the aspect of the color level, the influence of high contrast on an image is not obvious. The contrast has a greater impact on the dynamic video display effect. Because of the fast conversion of light and dark in the dynamic image, the higher the contrast, the easier it is for the human eyes to distinguish such a conversion process. The products with high contrast have more obvious advantages in detail performance, clarity, and high-speed moving objects performance in some dark scenes.

Projector brightness

The brightness of the projector is usually expressed by light out, which describes the ability of light source radiation to produce a visual response in unit time, and its unit is the lumen. There are two methods to measure brightness. 1. The average brightness of 9 intersections of "Tian" is multiplied by the length and width of projection. Test precondition projection distance is 2.4m; the projection size is 60 inches. 2. All black and all white contrast method. Select a black-and-white contrast image, measure, and calculate the black-and-white brightness difference times the projected area. When choosing the projector to determine the brightness index, we should not only consider the size of the used space but also consider the influence of the use of environment brightness. And the brightness selection should leave a margin, and the brightness will decrease after a period of use due to the influence of the bulb. It is recommended to choose 800-2000 lumens for the brightness of the home projector, 2000-4500 lumens for a small conference room or standard classroom, 3500-5000 lumens for medium conference room, and ladder classroom, and 5000 lumens for large conference room or auditorium. Of course, this is only a reference value. The accurate brightness should be calculated according to the actual ambient brightness and the size of the screen. For example, taking the classroom as an example, the average brightness is 500lux, and the formula is projector brightness = ambient brightness * 2 (Times) × screen length * screen width * 1.2 (loss coefficient) ≈ 3300. Therefore, it is necessary to fully consider the use environment and cost performance to select the appropriate brightness index.

Projector lens

Zoom ratio: the ratio of the maximum focal length to the minimum focal length, that is, the zoom ratio of the projection picture under a certain projection distance. This parameter does not affect the projection distance, etc.

Projection ratio: projection distance / screen width.

Lens focal length: distance from LCD panel to lens, unit: mm

Projection distance: distance from lens to screen, unit: mm

Panel size: LCD size in inches

Screen width: the effective width of the screen, in inches. It should be noted that the aspect ratio should be the same as that of the panel.

Calculate the projection distance according to the projector: projection distance = screen width * lens focal length/panel size

Projection distance = screen width (mm) × projection ratio

Calculate the appropriate projector according to the site conditions: lens focal length = projection distance * panel size/screen width

Precautions for projector installation:

1. Accurately calculate the projection distance, which is the distance between the lens and the screen; align the projector lens with the left and right center of the screen as much as possible; calculate the installation height of the projector according to the difference between the lens and the screen height (refer to the projector manual). Special attention shall be paid to this item when using a fixed focus projector, so as to avoid that the image cannot be full screen or over the screen. In case of slight error, fine adjustment can be made through the relative position between the projector and hanger.

2. During construction, pay attention to load-bearing reinforcement for the installation position of the projector and curtain according to the actual situation on site.

3. Try to select the projector hanger with excellent quality. The poor hanger is not perpendicular to the roof, and the installation screws cannot be tightened. Such problems affect construction efficiency.

4. If the electric screen is selected, a strong electric socket shall be reserved in the screen box, and the electric screen shall be equipped with remote control as far as possible to avoid affecting the appearance.

5. Do not power off the projector immediately after debugging. After the bulb cools and the fan stops rotating, cut off the power.

6. For projector cable, VGA, HDMI, and other cables can be reserved according to specific requirements, and network cable can be reserved according to specific functions of the projector.

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.

Come to KCEL to learn Chinese!

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.

More about Tips for learning chinese characters.

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.

Learn spoken chinese

The first step is to grasp the useful basic knowledge of pronunciation. It includes: First, pronouncing the consonants and the vowels correctly, which is the basis for learning Mandarin Chinese well. Second, reading common words, this is a shortcut to learn Mandarin well. In modern Chinese, there are 2500 commonly used characters and 1000 sub-commonly used characters, their use frequency accounts 99.48% among all Chinese characters, so we can basically achieve the standard pronunciation and recitation of the demand in Mandarin as long as we grasp the standard pronunciation of the commonly used characters and the sub-commonly used characters.

The second step is to know the differences between local dialect and Mandarin. First, we should grasp the standard pronunciation of the commonly used characters and the sub-commonly used characters, and then "environmental memorize" the words easy to be read wrong in the detailed language environment. Through reading and memorizing some famous works of ancient and modern, Chinese and foreign, can effectively help the learners to remember the standard pronunciation of these words for a long time, and can also improve the cultivation in other aspects. At the same time, we should frequently listen to the radio, tape, watch TV and listen to the conversations between the native speakers. Using these "modernization" methods to create a special small environment for yourself to learn Mandarin, and constantly revise our irregular pronunciation.

The third step is to practice more and speak more. More practice and more speaking is the most important way to speak Chinese language well.

The fourth step is to actively participate in the internship of artistic language. Through reciting, speaking, telling stories and other artistic language learning, practice and internship, cultivate and further strengthen your interests in Mandarin and exercise the feeling of speaking Mandarin Chin
