According to the Ministry of Commerce, the WTO has released the world trade statistics report. From the global trade volume data, the world trade in goods and services nearly doubled from 2005 to 2015. After a modest rise from 2012 to 2014, world energy prices fell by 45 per cent in 2015. Regionally, Asia, Europe and North America accounted for 88% of the total trade in goods of WTO members, and the share of developing countries in exports increased from 33% in 2005 to 42% in 2015. Meanwhile, trade between developing countries rose from 41 per cent to 52 per cent in a decade. In terms of goods export, in 2015, the export volume of the top 10 countries accounted for 52% of the total export volume, while that of developing countries accounted for 42%. The total export volume of WTO member countries reached 16.2 trillion us dollars. In terms of service trade, the top 10 exporting countries accounted for 53% of the total export volume, developing countries accounted for 36%, and the total export volume of WTO member countries reached 4.68 trillion us dollars.

In 2015, according to the global trade volume data, world trade showed a weak trend -- the total volume of world trade grew at a slow rate of 2.7%, basically in line with the growth rate of world GDP (2.4%). However, as export prices fell by 15 per cent, the value of trade in goods (in dollar terms) fell by 13 per cent to $16 tn. World business services exports were $4.754 billion, down 6 percent year-on-year. The weak world trade in 2015 was mainly due to the economic downturn in China, the severe recession in Brazil, the sharp decline in the price of crude oil and other commodities and the unstable exchange rate. In 2015, the import demand of Asia and resource-based economies slowed down, while that of the us and EU strengthened.

The world trade volume data report said the total value of trade in goods was stable due to a stable dollar and a moderate rise in crude oil prices, but the outlook for the full year was not optimistic.

论文抄袭

在美国留学时， 论文抄袭 是很多学生会误入的雷区。首先，因为英语并不是我们的母语，所以在使用起来并没有那么得心应手，难免会需要参考别人文章的结构和文法，稍有不慎，就会借鉴过度，产生学术不诚实的问题。另外一个重要原因是在上大学以前，我们没有系统学习过如何规范引用他人文献，参考别人的文章时，不知道如何做合适的标记。

然而还有一种特殊情况会令很多留学生倍感委屈，那就是明明你是好心将论文给朋友借鉴，被老师发现以后还要接受处分。今天要分享的S同学案例就是如此，在一次小论文的截止日期前，和她同上一节课的Z同学说自己不太明白教授的要求，想借她的论文参考一下思路。因为是一个班的同学，S同学想能帮就帮他一下，于是便把自己写了一个周的论文发给了他。

没想到的这一个小小的“善举”却给她惹出了大麻烦，论文提交不久她就收到了一封来自Dean邮件，说她的作业论文与别人的相似度为70%，涉嫌论文抄袭，需要和她进一步约谈来判断是否需要开听证会。看到这个消息的S同学一下子慌了神，连忙去找Z同学商量，希望他能够为自己澄清，没想到对方却要逃避责任，选择不去找Dean谈话，而且劝说S同学也不要去，否则会越描越黑，得到的处分更重。

求真助力

进退两难、无法抉择的S同学向求真教育寻求紧急帮助。姚老师在了解了整件事情的前因后果后，建议作为被抄袭者的S同学一定不能放弃和Dean约谈的机会，而且要在聊天过程中占据主动。首先要诚恳地承认自己的错误，其次要完整地叙述事情的真相，解释清楚自己在此次事件中的角色，只有这样才能将对她自己的处分降到最低。

之后，为了让S同学在与Dean约谈时显得更加有条不紊、从容不迫，姚老师和S同学反复进行情景模拟，并提出让她用自己的论文草稿作为辅助证据证明写作过程，争取做到滴水不漏。皇天不负有心人，谈话结束后，Dean觉得S同学态度诚恳、有理有据，所以撤销了对她的处分。

求真寄语

虽然我们有时很难拒绝别人的请求，但是也要把握好分寸，保护自己的权益，避免自己因此受到伤害。 与此同时，万一还是不慎误入困境，一定要记得采取主动，尽快寻找专业机构来获取最有效的解决办法，不要轻易退缩或逃避，最终将事情推到万劫不复的境地。求真教育致力于帮助每一个海外学子完成他们的学业梦想，也在此衷心希望同学们都能够前途光明！文章来源：https://indeededu.com

网课模式开启

由于疫情影响，北美各大高校都宣布停课，留学生纷纷开启了宅家 网课 模式。

而最近很多大学又发布了一条消息：下学期继续提供网课，这也就意味着留学生的网课模式至少要持续到今年夏天。

图源：西蒙弗雷泽大学官方消息

虽然说这也是没有办法的事情，只能寄希望于疫情早日得到控制。但是说到网课，大家都是忍一时越想越气，上一节越想越亏，毕竟，这槽点也太多啦！

★ 你卡，我也卡，大家都卡

每次上网课，最大的难题不是听不懂讲课，而是网络太卡了，老师滔滔不绝的演讲都变成了电音表演，还时不时就掉线，让人有一种梦回2G时代的感觉。

https://cdn.indeededu.com/uploads/2020/04/3-300x70.png 300w, https://cdn.indeededu.com/uploads/2020/04/3-768x180.png 768w, https://cdn.indeededu.com/uploads/2020/04/3-705x165.png 705w, https://cdn.indeededu.com/uploads/2020/04/3-450x105.png 450w, https://cdn.indeededu.com/uploads/2020/04/3.png 1400w" sizes="(max-width: 1030px) 100vw, 1030px" />

但是谁能想到，这些“感觉卡顿”的同学才是幸运儿，被卡到进不去直播间竟然是常态；好不容易挤破了头，却发现进度已经推得飞快，教授开始滔滔不绝讲起了下个章节。

就算今天走运，网络非常流畅，没有掉线情况，网课的进行也需要强大的想象力和脑补能力……真的啥也看不见啊！

★ 你难，我也难，老师最难

且不说这个网络逼“疯”了多少良家学子，上网课这件事本身已经难倒了众多教授。没错，你的教授也许可以轻易解出数学难题，讲解法律条文，甚至给你讲讲逻辑与艺术，但是用电子产品上课，却是渡劫级的难度。

我们要知道，老师们也是很想上好网课的。然而，尽管已经拼尽全力想要好好上课，甚至在门上贴上“上课中 请勿打扰”的标签，没想到还是栽在了各种各样的沟里……

物理课已经快结束了，然而老师还没来？一看发现去了隔壁法学的直播间。

来自学生的无情拒绝，也成了老师耻辱下播的罪魁祸首：

★ 你鸽，我也鸽，连教授都鸽

为什么大家都不喜欢上网课？很大的原因是形象问题。由于宅在家里不修边幅，很多同学的摄像头里自己是这样的：

https://cdn.indeededu.com/uploads/2020/04/13-300x281.jpg 300w, https://cdn.indeededu.com/uploads/2020/04/13-450x422.jpg 450w" sizes="(max-width: 296px) 100vw, 296px" /> 图源：网络

老师们就更惨了，不仅需要自己演独角戏，他们的网课界面中，学生们表情严肃（呆若木鸡）大概是这样的：

https://cdn.indeededu.com/uploads/2020/04/14-300x211.jpg 300w, https://cdn.indeededu.com/uploads/2020/04/14-450x316.jpg 450w" sizes="(max-width: 461px) 100vw, 461px" /> 图源：网络

在这样的线上授课环境中，很难保证学生们不开个小差，做一些网上冲浪之类的操作，这样上网课，和签了到就走也没什么区别。

对此，细心体贴的老师们为了照顾大家，特地缩短了教学时长。这是什么精神？这是为了学生心理健康着想的划水精神。

https://cdn.indeededu.com/uploads/2020/04/15-300x77.jpg 300w, https://cdn.indeededu.com/uploads/2020/04/15-450x116.jpg 450w" sizes="(max-width: 589px) 100vw, 589px" />

这些槽点估计大家互相之间都吐槽很多遍了，毕竟特殊时期在家待着人类的吐槽本能都被挖掘出来了。

当然，也有的小伙伴因为上网课发现了自家老师不为人知的一面，怪可爱的。

https://cdn.indeededu.com/uploads/2020/04/17-300x58.jpg 300w, https://cdn.indeededu.com/uploads/2020/04/17-450x87.jpg 450w" sizes="(max-width: 463px) 100vw, 463px" />

当然吐槽归吐槽，该上的网课还是要上的，毕竟关乎学分。为此，小伙伴们需要避免一种现象：网课作弊

新冠肺炎疫情在美国蔓延期间，大部分留学生都已经开始了在家上网课的生活。

然而不少留学生在此期间懈怠学业，通过黑心代写、网上搜索答案来应付网课的作业及考试。虽然网课对于学生的课堂、课后参与度大大降低，但是美国大学的高压学术政策却一刻没有放松。

网课期间如果被学校发现有学术不诚信行为，如抄袭、作弊、代写代考，学生处理起来更加需要谨慎。正所谓“塞翁失马，焉知非福”，网课作弊、抄袭在美国大学同样是严重违反学术纪律的行为，一旦被发现，学生将面临严重的处罚。

因为学术不轨被停学、开除的学生不占少数，这不仅涉及到学生身份失效的问题，而且对个人的经历也抹上了一层阴影，对之后重新申请也有不小的影响。求真教育在处理这方面的问题上有着丰富的经验，如果紧急情况一旦发生，请在第一时间联系专业的机构进行处理，往往能将损失降到最低。

★ 求真寄语

虽然现在的情况让大家不得不宅在家里，但这并不能成为你懈怠的理由。在你坚持不住想要“放纵”的时候，提醒自己：别人都在努力。

求真教育愿大家在特殊的社会情况下能够保持初心，尽量习得更多的知识技能，让自己的留学生涯不留遗憾

If the rivet seat of the rivet is pulled out of the normal position, the rivet head position will appear obvious deviation after installing the rivet head, the red safety cover should be dismantled at this time, and the rivet seat can be used after the installation is in place, otherwise the machine can be easily damaged.

9. The guide rail of the equipment should be smeared with butter once a month to lubricate and prevent rust.

10. In the use of the rivet head, there will be slight adhesion when processing certain materials. In order to ensure the quality of the riveting, the rivet head should be cleaned regularly to prevent the metal bond from thickening. When cleaning, fix the rivet head to the chuck of the lathe and then polish it with sandpaper.

Solid rivets are suitable for solid rivet machines, also called rotary riveting machines. Commonly used products with solid rivets are mostly hardware products.

A spiral pipe machine is a machine that produces a spiral pipe. Spiral pipe, also known as spiral seam thin-walled pipe, was first used in the military industry of Western countries, such as warships, steamships (supply) air system, and later used in trains, subway, mines, and other civilian facilities. By 2000, according to statistics, the application of spiral pipe in office buildings, shopping malls and metros in the United States had reached 95.6%, and the application of spiral pipe in central air-conditioning in residential buildings had reached 72.5%.

The special pipe is a thin-walled pipe with spiral seam made of metal strip coil. It is round, weldless, leak-free and water-free. It is mostly used for air supply and bulk material transportation instead of traditional white iron pipe (i.e. manual seam-biting iron pipe). It is a kind of air duct, full machine straight pipe, without manual knocking.

Its main uses are as follows:

1. Air supply, including ventilation, such as fresh air supply and exhaust, covers a wide range of areas, such as factory workshops and production sites, which need to be discharged outdoors due to the generation of harmful gases, and also need to transport outdoor air to indoors. At this time, it is necessary to use air conveying pipelines with a large flow and low pressure. Spiral pipes are most suitable. Generally, galvanized iron tubes are used, and stainless steel tubes are used in corrosive and especially humid places.
2. Cold air supply. The most common is the central air-conditioning pipeline, which requires insulation materials. The spiral pipe can be insulated with heat preservation material and has a beautiful appearance.
3. Fume exhaust. The kitchens of restaurants, restaurants, and hotels all have a lot of oil fumes, which need to be discharged. The use of circular air ducts is the oil chimney. Here, the spiral pipe should be called lampblack.
4. Dust removal. In some factories, there is a lot of dust in the workshop, and special dust removal devices are needed. The spiral duct can be used in the pipeline with larger air flow.
5. Bulk material transportation. In the production process of some factories, loose particles need to be transported, especially those with a small proportion, such as foamed plastic particles, which use spiral pipe with low cost and good effect.

Because the spiral pipe machine can only produce straight pipes, elbow machines and other equipment have been developed. Among them, the double spiral elbow machine can achieve a high degree of production flexibility by operating at the same time through two individual workbenches: one is the curling workbench, the other is the biting workbench. Therefore, the machine can be used freely at any time without time-consuming conversion. Two workbenches work at the same time. The product is not only beautiful in appearance, but also firm, and light in weight.

Vertical installation of pneumatic ball valve is possible. Generally, installation on pipeline can be divided into parallel installation and vertical installation, which is based on the actual situation of customers. But we recommend that it is generally best to install in parallel, so that it can be easily maintained and it is very beautiful. But in many special cases, pneumatic ball valves can also be installed vertically.

How to install the pneumatic ball valve?

How is the pneumatic ball valve installed? Can the pneumatic ball valve be installed vertically?

Vertical installation of pneumatic ball valves is possible. Generally, installation on pipeline can be divided into parallel installation and vertical ball valve installation, which is based on the actual situation of customers. But we recommend that it is generally best to install in parallel, so that it can be easily maintained and it is very beautiful. But in many special cases, pneumatic ball valves can also be installed vertically. Customers said that the pipeline space of parallel installation is not enough, then it will be installed vertically, which will not affect the service life.

Sealing position of pneumatic ball valve

Pneumatic ball valve seal generally consists of four seals: 1. Stem seal ring 2. Midway seal ring 3. Two seals on both sides. Stem seal ring refers to: seal ring where the valve stem operates, generally with tetrafluoro (PDFE) and flexible graphite; the middle seal ring refers to: the middle connection valve body seal, generally with tetrafluoro (PDFE) and graphite metal composite gasket; the two sides of the seal ring are: the ball core on both sides of the import and export seal ring. It is generally sealed with tetrafluoro (PDFE) and PPL (high temperature resistant sealing ring).

Pneumatic Ball Valve Actuator

The pneumatic ball valve consists of two main parts: actuator and valve. The actuator has two kinds: single-acting and double-acting.

So how to make your pneumatic ball valve easy to use and has long life? The service life of pneumatic ball valves is determined by the on-site use of customers.

To prolong the service life of pneumatic ball valves, the first thing is to keep the gas source stable. The stable gas source can directly affect the speed of the valve switch and the life of the valve sealing ring. It is better to install a couplet on each actuator. This couplet can not only provide stable air pressure, but also regularly refuel the cylinder. It can also discharge moisture from the air, which greatly improves the life of the cylinder. The life of the valve is determined by the medium used in the field.

Professional pneumatic ball valve manufacturers and high quality ball valve will make its life longer. Among various pneumatic ball valve manufacturers, Zeco is the best choice for you. Zeco provides you with high quality pneumatic ball valve products.

Do You Know How Does the Spiral Tube Forming Machine Cope With Low Temperature Environment?

Expansion caused by heat and contraction caused by cold will do damage to tubes. Today, I' m going to talk about how to cope with this trouble of spiral tubes in the cold regions of the north or in winter.

First of all, it is the selection of thermal insulation materials and it should be good for insulation performance. The specifications of thermal insulation materials should conform to the use of the windpipe system. It should also meet the design requirements of the tube. The insulation materials used should have certificates like qualified certificates, so as to guarantee the effective protection of the tube when used, so that it is not easy to damage when used in winter. The tube generally chooses the refractory closed hole rubber plastic sponge insulation material, and the smoke exhaust tube usually uses nonflammable aluminum foil glass cotton plate. These two kinds of materials are widely used, and the insulation performance is better.

Second, when the spiral tube is wrapped with thermal insulation material, the cutting is accurate and the cutting surface should be flat as far as possible. In this way, the bonding can be ensured. When cutting material, the horizontal-vertical surface should be overlapped with the top of the short face on the beam.

At last, when coating the spiral tube with thermal insulation material, the thickness of the glue should be uniform, and the glue can not flow when the glue is coated. When the insulation material is overlaid, it is effective to ensure that the adhesive bonding is tightly bonded. The adhesive place will not have the empty drum, and there will be no air pipes exposed to the outside tubes.

We must make full use of the spiral tube scientifically so that we can let it make a greater contribution to our life.

Diamond has some remarkable properties: for example, its refractive index is 2.4, which is very high, and can be made into thinner optical components for optical systems with the same optical power. Their thermal conductivity is 2000 W/m*K, 1400 times higher than that of optical glass.

So far, polycrystalline diamond substrates have only been used as light windows for carbon dioxide lasers. Due to impurities and defects, they absorb and scatter laser radiation at the emission wavelength of 1 micron, so they are not suitable for fiber lasers. Although single crystal diamonds do not have this problem, they are difficult to manufacture. Over the years, the German Fraunhofer Institute for Applied Solid State Physics (IAF) has been devoted to the production of single crystal diamond. The continuous vapor deposition (CVD) reaction chamber developed in IAF has stable plasma conditions and it can produce a substrate with a thickness of several millimeters.

It can simultaneously process 60 diamonds at most. At a rate of up to 30 microns per hour, the reaction chamber can produce an optical element with an aperture of about 10 millimeters.

The lenses made of these synthetic single crystal diamonds have low absorptivity and low birefringence. At present, some samples coated with antireflection film have been provided and used in fiber laser cutting head. "We have optimized a complete hyperion laser optical system for diamond lenses for the first time, and the weight of the cutting head has been reduced by 90%," said Martin Traub of the Fraunhof Institute of laser technology".

The lens with a diameter of 7mm has passed the test of 2 kW laser power, without any problems. Now, partners have built a cutting test system using 1kW fiber lasers. Water cooling and protective gas supply are integrated in the cutting head. Process monitoring has not been planned. Currently, compact cutting heads is in process of testing for the first time.

A new optical system will significantly enhance the flexibility of laser cutting. The small size enables the system to process inaccessible areas, while the low weight is beneficial to the high dynamic motion in the 3D process.

Speaking of marriage, what has to be mentioned is the wedding dress. Almost every girl has a beautiful yearning for the wedding dress. It is a special feeling different from a beautiful garment, which is combined with the hope of love and happiness. When choosing a wedding dress, many girls always think that only the current mainstream- white wedding dress can be called the wedding dress. They are not aware that there are many other colors of unique wedding dress. Let's take a look at them together.

Pink wedding dress

Pink wedding dress

Pink quinceanera dresses is sweet and beautiful and full of warm and romantic atmosphere, leting people fall in love at first sight. With the texture of the yarn, it gives people a gentle and flexible feeling, and adjusts a gentle temperament in the solemnity of the wedding. The color of pink represents the sweetness of love and the beauty of the future. Choosing pink as wedding dress, the fairy's wedding is a romantic celebration.

 Golden wedding dress

Gold wedding dresses

Since the Song Dynasty in ancient China, yellow was the special color of the emperor. Because gold has a similar color, many people regard it as a gorgeous symbol, representing wealth and luxury. Gold is also the color of the sun, implying warmth and happiness. Therefore, choosing a noble and luxurious golden wedding dress will make the bride have a radiant charm and give people a sense of retro dignity and inviolability.

Purple wedding dress

Purple is elegant and gentle, solemn and gorgeous, which is the symbol of mature women. It is also a good choice to apply gold to wedding dress. On the wedding day, it is ingenious to use it to mark your growth. If the lady is full personality, independent, and generous, she can definitely hold the purple wedding dress. The bride will be ecstatic wearing such a  generous and luxury dress plus the color of lavender.

Blue wedding dress

Blue wedding dress

Blue gives people a quiet, remote, faithful and credible feeling. Blue wedding dress, like the sea, can tolerate everything, which is also a reminder to the girls, to accept the unpleasant and imperfect marriage, to overcome obstacles together, to face with a positive and ordinary heart, in order to achieve a true and plain marriage. And the blue wedding dress is noble and elegant, full of romantic atmosphere, which shows entirely the charming of the bride.

Black wedding dress

Black wedding dresses

At the present time when white wedding dress is the mainstream, there are some "special brides" who break the tradition and show the taboo beauty with Gothic style black wedding dress, showing the unique sexy and fashion. The atmosphere created by bride wearing a black wedding dress can not be given by any brides who wearing white wedding dresses. In traditional marriage in China, black is not a generally accepted color, especially for wedding dress. But in this era of pursuing individuality and creativity, subverting tradition has become the theme of the times.

The sweetness of pink, the luxury of gold, the elegance of purple, the tranquility of blue or the subversion of traditional black, all give people a feeling of wide-open vision. Today, as the mainstream of white wedding dress, you girls may as well try different colors of wedding dress, I believe it will have a different taste. If you need custom made dresses online, please contact us.

The core problem of underwater activity of divers is that humans cannot ingest oxygen from water, therefore, it is necessary to carry gas cylinders or to supply gas from the water surface, and the breathing problem has become one of the most complicated technologies in diving technology. But the water actually dissolves a certain amount of oxygen, fish is through the gills to absorb oxygen from the water to maintain life. In theory, if you can master the rapid uptake of oxygen from water, then humans do not need to carry gas in the underwater activities. But keeping breathing for a long time under water has always been considered unthinkable and impossible, scuba diving can only continue to be carried out underwater by carrying air or by piping. Because fish can absorb oxygen from the water by their gills, humans and mammals don't have gills, and they can't use oxygen in the water to support life.

Do you know how fish breathe underwater？

Let the human fish breathe oxygen in the water for a long time to survive in the water, it sounds like science fiction, and Danish scientists have recently been able to get oxygen permanently underwater, which is a step toward that goal. It's because of the kind of crystal material they developed, this synthetic material is named Neptune crystal AquamanCrystal. This synthetic material can continuously ingest oxygen from air and water without any other means. The oxygen absorbed by the crystal can be released as long as it is heated slightly or exposed to low oxygen pressure. At present, it is difficult to produce this kind of synthetic crystal material in large quantities.

The implications of this finding are profound, says Christina Mackenzie, a professor at the university of Denmark, who led the research. She told the science daily: "this material can absorb oxygen from the air. Patients with respiratory dysfunction need daily oxygen, the technology will allow patients to get rid of heavy oxygen tanks. Divers may also use the technology in the future to carry a small amount of this crystal grain. The diver breathes the material into the water to absorb oxygen that is dissolved in water, so there is no need to carry gas cylinders or supply the gas from the water. So they named the crystal AquamanCrystal.

Neptune crystals have a spongy composition that absorbs oxygen.

Neptune crystals absorb oxygen and rely on cobalt ions. This is very similar to the ability of hemoglobin to absorb oxygen. Because oxygen is difficult to dissolve in water and blood, all living things on earth use metal ions to combine and transport oxygen. The hemoglobin in the blood of people and many animals depends on the combination of iron and oxygen. Myoglobin, the myoglobin in muscle cells, is also a similar molecule. Animals such as crabs and spiders rely on copper ions to combine and transport oxygen. The ability of metal ions to absorb oxygen is huge. So it's not surprising that this crystal glass has a powerful ability to absorb oxygen.
