"Mom, isn't the intercooling and heating device just a heat exchanger? Is it that difficult?" Liang Yuan looked at Li Yuanling with confusion with his eyes.

Li Yuanling looked at her extremely mature son who showed her innocent side, and chuckled gently, cleared her throat and said, "Xiaoyuan, don't underestimate the most basic things in industry, such as heat exchangers. You must know that in science and technology, the more basic things are, the simpler things are, the harder they are to break through."

"It's like mathematics, like the Goldbach conjecture, which was studied by the great mathematician Chen Jingrun, in a great mathematician, to put it bluntly, it is to study the problem of one plus one and one plus two equals." Comrade Lao Liang found a rare opportunity for education and quickly interrupted.

"What nonsense? Goldbach's conjecture is to prove whether every even number greater than 2 can be written as the sum of two prime numbers? Jiang Kun and Ma Ji and others said during the Chinese New Year, you are embarrassed to take it out and tell your son?" Li Yuanling said with a blank look on Liang Jiangping.

Liang Yuan looked at his parents with some amusement, and found that his mother was about to explain in detail and quickly changed the subject.

The Goldbach conjecture that this thing has troubled the entire human race for more than a century. After the speed of electronic computer computing has greatly increased in later generations, the United States connected thousands of super servers to calculate such mathematical problems. As a result, many mathematical problems in Liang Yuan were still not very important.

In the words of a senior mathematician, with a century of time as an era, among the 6 billion people around the world, there are never more than 20 geniuses who are suitable for mathematical problems such as the Goldbach conjecture. With the mathematical level of his father at high school, he can not explain it clearly in a short time.

"Mom, what is the use of studying these basic mathematical problems?" Liang Yuan asked curiously.

"It has great use. Mathematics is called the mother of science and the engine and the flower of industry. It has the same principle. Xiaoyuan knows the concepts of prime numbers and prime numbers, right?"

Looking at Liang Yuan nodding, Li Yuanling continued: "For example, the large number of applications of prime numbers and prime numbers in cryptography make modern cryptography more and more difficult to crack."

"For example, the frequency changes of missile-guided radars are in the form of prime numbers. Considering from the perspective of electronic interference, a deep understanding of the mathematical Mason prime numbers will be easier to crack or interfere with this irregular change. For example, the power transmission between the gem turboshaft engine and the generator made by my mother now uses gear transmission, and mathematical prime numbers should also be used in gear design to find the number of gear teeth and gear angles with the minimum mechanical loss and failure rate."

Listening to Li Yuanling talking about the important application of mathematics in industrial production, Liang Yuan sighed secretly, thinking that in the future, there is no idea which 2b-dead fool proposed that the college entrance examination would cancel mathematics, and even the waste of basic mathematics. What is the use of college students in society? Since you don’t want to learn mathematics, you can write with your body, or go racing a car, sing a song, filming a movie, etc., which is much richer than going to college. Why do you have to squeeze in the college entrance examination with a silly face?

No wonder the Republicans in the United States never look down on the so-called masses, and always sit on the side of the elite. For some ignorant people, they hope to get something for nothing, take advantage of the opportunity, and take shortcuts, and their voices are the full meaning of their lives. From the perspective of the ruling class in the United States, the meaning behind the so-called "Lamb of God" in Western proverbs is so scary. Who is whose God and whose Lamb?

Li Yuanling looked at Liang Yuan's eyes and wandered around. She first pinched Liang Yuan's cheek, and then suddenly realized that she had entered a professional state again. She smiled with a self-deprecating smile and said, "Mom has pulled things apart again, but as for the medium-cooling and heating device, a simple understanding is to make a larger heat dissipation area in the smallest space. Faced with the high-temperature exhaust gas of gas turbines, the traditional pipeline exchange radiator completely does not meet the requirements in terms of volume efficiency, and can only use a brand new plate-fin radiator."

"According to the principle of thermodynamics, under the same conditions, the larger the surface area, the faster the heat exchange rate of objects with a larger surface area. Therefore, in terms of the performance of the plate-fin radiator required by the gas turbine, it is necessary to reach a heat exchange area of ​​at least 5,000 square meters in one cubic meter of space to have practical value in engineering. If the outlet temperature of the unit exhaust gas is reduced to about 200 degrees, the heat exchange area must reach 15,000 square meters. In other words, it is equivalent to stuffing the surface area of ​​two football fields into a cubic meter of space. A large amount of media responsible for heat exchange still needs to flow quickly. Xiaoyuan said that this is difficult or not difficult?" Li Yuanling looked at Liang Yuan with a smile.

Liang Yuan was already stunned by hearing this. No wonder the United States is currently in love with developing a simple cycle gas turbine. The difficulty of this intercooling and heating device is simply amazing. What Liang Yuan didn't know is the world's first high-power ship-purpose gas turbine unit wr21 using intercooling and heating device. It only started its R&D plan in 1991. With the joint cooperation between the United Kingdom, the United States and Canada, it took ten years to successfully develop it.

"That's why my mother told you that supercomputers are the basis for future technological research and development. Thermodynamic conversion and fluid flow design of intercooling and heating devices have completely exceeded the limit of human computing. Without a supercomputer, you can't even think of designing it for a hundred years. Mom has countless projects waiting for Lao Su and their supercomputers."

Listening to Li Yuanling once again emphasizing the importance of supercomputers, Liang Yuan was deeply moved that the United States in the future gained a huge advantage in mathematical computing with its leading position in the semiconductor industry. After the collapse of the Soviet Union, it detonated the third industrial revolution in human industry history and further grew into the only superpower on this planet.

If the capitalists were not too greedy and had the serious industrial hollowing out in the United States, the Republic would have no chance of rising decades later.

Liang Yuan followed Li Yuanling in the Science and Technology Park for a short time, and got many real surprises. In the past year, Liang Yuan's main energy was on the F14 fighter jet and the Nansha Battle, which was related to the future of the Republic. Every time he came to the Science and Technology Park, he was in a hurry. Today, he went around carefully and found that there had been great changes.

Including fixed investments such as equipment and factories, the entire Nanhu Science and Technology Park burned at least 1.5 billion yuan throughout the year, and Liang Yuan spent all the money all over the world. In addition to the necessary working capital, the entire group basically invested the rest of the money by Liang Yuan in the Science and Technology Park and Changbai Island.

At this time, the Science and Technology Park no longer looked a little shabby when it was first created. Under the shade of a patch of green pines and cypresses, eight or nine large steel structure buildings, either blue or white, were scattered among them. The blue belonged to the gas engine laboratory, and the white belonged to the electronic laboratory.

The metallurgical laboratory, which originally occupied a large area in the Science and Technology Park, was moved by Zhu Liguo to Benxi. Currently, there are only three or two big cats left behind in Nanhu.

On the electronics laboratory, Su Liangyu and others invested all the construction resources into the construction and transformation of two 5-micron production lines, while the infrastructure of the gas engine laboratory is blooming everywhere.

Since the life problem of high-temperature resistant metal materials has not been solved, the scientific research tasks of the gas engine laboratory this year are not heavy, and Li Yuanling has drawn some energy to build a large number of construction parts and built a series of test bench infrastructure parts used for testing various models of gas turbines.

In the process of research and development or improvement of aircraft engines, testing equipment is crucial. The simplest example is that without a large-sized supersonic aerial platform, it is impossible to develop a qualified turbofan jet engine. Just like Japan in later generations, although it reached the world's top level in some heat-resistant materials, even independently developing a small turbofan aeronautical engine is tantamount to dreams.

A few days ago, apart from some technical information, the remaining ones were engine-related testing equipment. Since the factory and other hardware facilities had been built, it took only two weeks for a gem turboshaft engine detection line that was exactly the same as the British Rolls-Royce Company was cloned by the Science and Technology Park. It can be said that the power core of the gas turbine motorcycle can be clarified in a short period of time. Li Yuanling's forward-looking planning made a contribution.

The few people walked around and talked until it was dark before leaving the Science and Technology Park and returning to the 909 community for dinner. After dinner, it was already past nine o'clock in the evening. Li Yuanling did not let Liang Haiping and his family go to the hotel, and drove Liang Yuan to the sofa in the living room to deal with it all night. Liang Haiping and his family lived in the bedroom where Liang Yuan usually slept.

The next day, Liang Jiangping and Li Yuanling, who had no other affairs, took Liang Yuan back to Benxi, where they had not been very busy this year. Liang Pan rarely caught his brother's figure and followed Liang Yuanfang like a little tail. Someone had to play in the business of taking care of children and accompany Liang Pan in the crowded department store with the children's park that had already been to countless times for a whole day.

February 5th is the traditional New Year's Eve of the Republic. Liang Yuan, who was light and light, slept a little lazy. It was not until almost noon that he was woken up by a call from Peking. He lay in the quilt and talked to the two little girls who were about to leave the Loli era for more than half an hour before Li Yuanling forced her to get up with her ears and went to wash up.

For Liang Yuan, who was used to living in the information age, the leisurely days in the 1980s seemed particularly difficult. There was no mobile phone, tablet, or Internet. Whether you have money or not, the main activities on New Year's Eve were to prepare reunion dinners, prepare dumplings and watch the Spring Festival Gala for more than ten years.

As the sky was getting dark, the phone on the sofa in the living room began to ring. Both Liang Jiangping and Li Yuanling were the heads of the unit. Those with winks knew that during the peak period of New Year greetings in the middle of the night, they had to leave private spare time for the leaders, so they all called the New Year greetings early.
