Successful fruit picking system

Although Zhai Xiaoguo is not a jewelry design major, his methodology for thinking about problems is still fine.

They Daxia, including the most famous jewelry designers in the world, have not won awards such as jewelry design awards or gem design awards for making the same things as their predecessors.

It is because of the introduction of new materials or the development of new craftsmanship that the jewellery industry has made progress to gain relevant honors.

For example, as mentioned earlier, some people have introduced new super-hard ceramic materials that are not easy to scratch, which have not been used in the jewelry industry before, into their designs.

In order for new materials to be combined with jewelry, new skills are needed;

Others spent several years to develop the technology of gem back carving and inverse carving with modern gem cutting technology that was not available before, so that the gems showed the effect of multiple exposure in the photography industry.

This is actually similar to the concept of doctors in other majors. They are all about breaking through the boundaries of the existing framework in their own fields and obtaining things that were not available before. It is by no means that the predecessors could use jade to carve a Buddha, but they can also use jade to carve a Buddha. Buddha, not worse than the predecessors can be satisfied.

Therefore, in "The Past and Present of a Pearl", the audience did not hear a sentence to show off a certain existing skill or technique.

Of course, blockbuster movies have their own themes, so they didn't use a long commentary to explain the problems of these conceptual routes. They just said one sentence:

"The craftsmanship will only be brighter if it cooperates with the continuous progress of productivity and technology."

Immediately afterwards, Huang Yidan's family and many audience members followed the camera, and together with the teachers and students of the United Nations University, tried all kinds of existing and unavailable technologies...

The first is the existing technology.

In the laboratory-like practical classroom for jewelry design majors, the teacher asked the students below whether they had mastered the techniques of designing subsequent cutting and polishing surfaces by testing the refractive index and dispersion rate of diamonds.

This is a very basic method, of course the students have learned it, but this is their first practical operation!

Now you can get started with the giant cultivated diamonds with a cost of 5 million. Not to mention students, even the teachers with indifferent expressions feel like their hearts are shaking and their hands are shaking...

The video also inserted one-on-one interviews with students in due course. The students said that Zhai Dong had threatened that if they did not do well, they would be treated as social animals in the future, and they would pay back their lives to the school and the enterprise.

However, the students laughed and joked. Obviously, they didn’t really sell themselves. Instead, they said before and after the film.

This is just an assignment for the students, but it will be put on the official website afterwards and sold under the name of the United Nations University Jewelry...

In fact, many universities have this kind of operation, but no other big brands have succeeded in business. After all, other big brands have to compete in the market. Both good and bad methods are used.

For example, Zhai Xiaoguo has seen those agricultural universities selling his own agricultural products, and he has also bought products such as milk, oatmeal, and soy milk powder produced by the agricultural university.

These are all things that have not been added with additional pesticides and fertilizers in order to test the results.

Of course, since it is talking about pesticides and fertilizers, it must be emphasized that Zhai Xiaoguo learns scientific methodology, which is both logical and inductive, so he does not think that pesticides and fertilizers are bad things.

In fact, it is precisely because people have human medicines, agricultural products have agricultural products medicines, and livestock have livestock medicines, people's lifespan and quality of life have been greatly improved, instead of being designed in nature to reproduce in their teens and then 2. He died at the age of 30 for various reasons...

The scientific route will not be like environmental terrorists, or organic and ecological terrorists, wishing to get rid of pesticides, fertilizers and related industries, scientists, etc., but this does not mean that people cannot pursue a higher quality of life and a longer life. Life expectancy, and put forward higher requirements, requiring better human and agricultural drugs, etc., and even in the future, it may be possible to use less or no drugs.

Because no one has stipulated that with the advancement of technology and productivity, people and agricultural products in the future will not use less medicine, more refined, or even no medicine!

But that must be because of progress, not regress!

For example, there has been an emergence of artificially controllable organic ecosystems instead of spraying pesticides, instead of returning to the uncontrollable level of ancient farming that caused people to starve to death every year...

Speaking of video blockbusters,

When the audience knew that these all-diamond jewels developed with the theme of pearls were just a homework for the students,

They all sighed that the UN General Assembly is a real trench, and can train teachers and students at such a high cost...

Of course, there are also many university students who have come forward. This one says that a certain instrument in their laboratory costs several million, and the other says that their laboratory costs tens of millions.

Some people say that the instrument is not expensive, but the cost of a single test.

For example, a researcher doing semiconductor epitaxial growth experiments said that they cost more than 200,000 yuan to run an experiment...

Well, the audience sighed, it turns out that the people who really throw money crazy with their hands are not the people in the luxury cars on the street, but the people who stay in the laboratory...

In the video, the instructor took the students to measure the refractive index and dispersion rate. Because the cultivated diamonds are very pure and uniform, the most important task is to delineate the starting point.

Then, they used several different methods taught before and started to work on the marking parts on the blank.

Including violent splitting method, diamond saw blade cutting method and laser cutting method...

The lens gives the shoe buckle first,

Because they want to remove the four arc edges to form a rhombus, they first tried the split method mentioned in the textbook, which has a long history.

It is a method of first ditching and picking grooves with a diamond blade on the line drawing part, and then applying force along the grooves to split.

This method is very similar to the use of the rock's characteristics of being very resistant to pressure but not resistant to tension when digging into a mountain.

However, they only tried this method once,

The narration is very clear, it is purely to let the students understand and try the methods mentioned in the book, because there are other better cutting methods.

Listening to the name of the splitting method, you know that he is a bit violent, and it may lose if you fail to split it. It is similar to using a glass knife to make a groove when cutting glass. When the result is hit and broken, it does not follow the desired line Breaks, so it causes losses,

So the students just tried it, and then it was over and changed to another method.

The second method is to try saw blade cutting.

Because the volume of diamonds is very large, unlike small diamonds, even if the temperature of the saw blades bonded with diamond powder is kept cooling down during the process, the saw blades are replaced several times to successfully cut off a redundant part...

On the ring side, because the finger hole is to be opened to form the part of the ring that can be inserted into the finger, a punch bit is used instead of a saw blade.

The masters and students of Lianhe chose the "diamond nanorod polymer" material punching head developed by Zhongyuan University of Technology.

Hole punching is very successful, and it can be regarded as a practical verification and advertisement for the other party's new technology.

Then, the teachers and students also used the laser cutting method, which is also a common method in gem cutting.

To be continued...
