The laboratory co-founded by Calvin and Marconi was located near the Jin Temple, and the two companies attached great importance to cooperating with Song Zhewu to develop wireless voice communication devices and new electronic products, according to the agreement, Calvin sent 32 researchers, while Marconi sent 15.

In the tripartite agreement, although the research results were shared by the three parties, Song Zhewu still took the initiative to propose a supplementary agreement that surprised Marconi and Calvin.

The agreement requires that the two companies must send outstanding scientific researchers to China, each batch shall not be less than 10 people, and the annual replacement shall be renewed, and if required by the Chinese side, individual researchers can extend their working hours in China according to the requirements of the Chinese side and on the premise of their own volition.

If approved by the Chinese side, Song Zhewu will not only have to pay the two companies $10,000 per person a year, but will also be responsible for the salaries and all other expenses of the arrivals, which will be between $800 and $1,000 per person per month.

Such a high salary, at this time in Europe and the United States, only a very few of the most outstanding people can get it. Such favorable conditions have been announced, and the two companies have set off a big wave, such a large sum of money, not to mention that in this era of economic crisis, even in the past, it was enough for a family to live a decent and happy life.

As a result, for a while, as long as they felt that they were good at learning, they all strongly asked to come to China to work.

In the agreement between Song Zhewu and the two companies, these researchers in China will not only engage in scientific research, but also arrange a certain amount of time for teaching. Moreover, if the personnel coming to China are not approved by the Chinese side, the Chinese side will return them and reduce the fees paid to the two companies accordingly.

Although $100,000 a year is not a lot of money, it is not the same in the current Great Depression, and it can solve the urgent needs of both companies.

And because the salary is paid by Song Zhewu, they can not only retain talents, but also save the salary expenses during this period, where can they find such a good thing?

The British are still more gentlemanly, and they are not embarrassed to "take advantage of this" too much, but they just sent 15 researchers from the company to China. But the Americans didn't have much scruples, and they actually sent 32 people at once, and according to Song Zhewu's understanding, among these 32 people, 22 people were scientists recruited by Calvin's company.

This is obviously Calvin's company wants to take advantage of the current depression period to catch high-level talents in advance, so that its company will be greatly developed in the future. Anyway, not only do these people's salaries not have to be paid by Calvin's company, but they can also earn hundreds of thousands more every year.

For the shrewd Americans, Song Zhewu not only did not feel unhappy, on the contrary, he admired Calvin very much, and it is no wonder that Calvin's company will become a large multinational company with the world's top name in the future.

For the scientific researchers who came, Song Zhewu was Han Xin's soldier, the more the merrier, the more people, the better, and he is in urgent need of such high-level talents.

Of course, for these foreign talents who come to Taiyuan, Song Zhewu also has to be assessed, and those who are unqualified will have to take a break. He is willing to spend money on talent introduction, but the money must be worth it.

The assessment work was naturally done by Li Minghua and Cui Hao, and the results made Song Zhewu very satisfied.

The joint laboratory's research focuses on in-vehicle wireless voice communication devices, high-power radios and radar technology.

As the chief researcher of the joint laboratory, Li Minghua only regularly went over to inquire about the progress of research and coordinate various tasks, and he spent most of his time at the Institute of Electronics.

It's not that Li Minghua thinks highly of himself, nor is it that Li Minghua is inactive, but that he has a top-secret mission given to him by Song Zhewu, which is only known to Cui Hao and a few people who participated in the research.

He is now organizing two projects: semiconductor technology and electronic computers. And this requires absolute secrecy, not only for these foreign experts, but also in the institute.

Song Zhewu knew that at this time, he wanted to have a large electronic computer, which he couldn't do with his current scientific research strength, but it was still necessary to conduct technical concept research in advance. If there is a little achievement in ten years, or even just the development of a small computer, it will be very difficult, enough to make him lead the world in the field of electronic computers for many years, and this will also be enough to ensure that he will be ahead of the world in many advanced technology fields for a long time.

In fact, Song Zhewu also has a computer project, which is a mechanical computer.

Mechanical computers have been developed abroad for hundreds of years, with the famous Turing in Britain and Baldwin in the United States. However, although these two types of computers also use electric motors, they are only substitutes for hand-cranked power, which are absolutely different from real electronic computers, and they should be called electromechanical computers more appropriately.

Although this type of electromechanical computer is not the development direction of computers, in this era when there are no electronic computers, it is still very promising to be used as ballistic aiming calculations and advanced bomb sights. It's just that this project is not being done by Li Minghua's electronics institute, but by the Institute of Mechanical Equipment.

As for semiconductor technology, it goes without saying that it is an important surname.

It is safe to say that the most important indicator of whether a country's electronic technology is advanced is whether its semiconductor technology is advanced. Fifty years later, any electronic product in the world is inseparable from semiconductor integrated circuits or semiconductor components, and if you are not a professional, you will never find a trace of an electron tube.

If Song Zhewu now has transistors and has developed mature semiconductor application technology, then his radio stations and electronic devices such as communication devices, radars, and computers, which are being developed intensively, will be able to have a smaller size and more powerful power.

You must know that the size of the world's first electronic computer is the size of a few rooms, because of the appearance of Song Zhewu, such a situation will never appear again.

And with the computer, many of the projects he is currently secretly conducting research will greatly improve the progress of his research, at least the scientific research progress of Zheng Dazhang's Institute of Physics.

Zheng Dazhang's ongoing research in nuclear physics requires a large amount of calculations, although the Institute of Physics has compiled nearly 100 people, and there are more than 40 college graduates who study mathematics alone, but they are still tired of dealing with those huge calculations...... It's not a dream.

This matter, no matter when, as long as Song Zhewu thought about it, it would make him excited.

The most important thing is that the principle of semiconductors will be clear to all high school students who have studied high school physics in later generations, and Song Zhewu, a master traveler, naturally has no reason not to know.

Song Zhewu still remembers the extremely shocked demeanor of the two when he handed over a little "experience" and "understanding" he wrote about semiconductors to Li Minghua and Cui Hao. Song Zhewu estimated that it would take at least half a month for the two to recover.

It's just that no one in the world today has realized the importance of semiconductor materials, let alone understood its function.

Song Zhewu knows that in real history, it was not until 16 years later, that is, in 1947, that the world's first transistor was invented by Bell Labs in the United States, and it was only a few years later that it was really used.

When Feng Rui's Agricultural Water Conservancy Committee directs the work, it is much simpler.

This is mainly because Song Zhewu was not a farmer in his previous life, and some of the agricultural knowledge he knew, in addition to what he often learned inadvertently in his previous life, and then he got it from the time travel novel, his knowledge is very limited. Although many of the agricultural technologies he knew were much more advanced than those of this era, Song Zhewu only knew a general idea, or a term, and Song Zhewu didn't know anything about what to do.

However, fortunately, there are experts such as Feng Rui and Zhao Chengxia, and many new agricultural technologies are just terms listed together in Chinese characters for Song Zhewu, a layman, but for professional and technical personnel such as Feng Rui and Zhao Chengxia, it is absolutely different.

For example, Song Zhewu only knows a rough idea of the plastic film covering technology, and knows that it has the functions of increasing temperature, water retention, fertilizer and increasing yield, but he is not very clear about the specific principle and mechanism of action.

With Feng Rui, a doctor of agronomy from Cornell University in the United States, there is naturally no problem. According to Song Zhewu, Feng Rui conducted a one-year experiment in Laiyuan, and basically figured out the mechanism of plastic film mulching.

Feng Rui told Song Zhewu. "Plastic film mulching has the functions of increasing temperature, water retention, fertilizer retention, improving soil physical and chemical quality, and improving soil fertility. In addition, it also has the effect of inhibiting the growth of weeds and reducing diseases. In the case of continuous rainfall, it also has the function of reducing humidity, thereby promoting plant growth and development, earlier flowering and fruiting, and increasing yield. And from this, a set of mature application technologies has been summed up, and it is ready to be fully promoted this year.

The main work of the Agricultural Water Conservancy Committee is to repair water conservancy, reclaim wasteland, popularize new agricultural technologies in the Taiyuan Administration and in the north and south of Mongolia and Suiyuan, and increase agricultural output under the administration of the Northern Frontier Governor's Office.

Because the farmers' farming and production techniques have been inherited by their ancestors for thousands of years, it is difficult to accept new technologies, and many people will even scoff at them, and new technologies cannot be promoted at all, which makes Feng Rui very helpless.
