"Mom, isn't the intercooling reheating device just a heat exchanger?" Liang Yuanka looked at Li Yuanling with puzzled eyes.

Li Yuanling looked at his extraordinarily old son showing a rare innocent side, chuckled gently, cleared his throat and said: "Xiaoyuan, don't underestimate the heat exchanger, the most basic thing in the industry, you must know that in science and technology, the more basic the thing, the simpler the thing, the more difficult it is to break through." ”

"For example, mathematics, like the Goldbach conjecture studied by China's great mathematician Chen Jingrun, to put it bluntly, is to study the question of how many times one plus one and one plus two are equal. Comrade Lao Liang found a rare opportunity to educate, and hurriedly interjected.

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

Liang Yuan looked at his parents arguing with some amusement, and felt that his mother was ready to explain in detail and quickly changed the topic.

Goldbach conjecture that thing has plagued the entire human race for more than a century, and after the computer computing degree was greatly improved in later generations, the United States had connected thousands of servers together to calculate such mathematical problems, but until Liang Yuan passed through, many mathematical problems were still not serious.

In the words of a veteran mathematician, in the era of a hundred years, among the 6o billion people in the world, there are never more than 2o surviving geniuses who are suitable for mathematical problems such as Goldbach's conjecture. Which is what my wife can explain in a short time.

"Mom, what's the use of studying these basic math problems?" Liang Yuan asked curiously.

"It's very useful, mathematics is called the mother of science and motivation is called the flower of industry, both of which are the same reason, and the concepts of prime numbers and prime numbers are known from afar, right?"

Seeing Liang Yuan nodding, Li Yuanling continued: "For example, the large number of applications of prime numbers and prime numbers in cryptography makes modern passwords more difficult to crack. ”

"From the perspective of electronic interference, a deep understanding of the mathematical Mersen primes will make it easier to crack or interfere with this irregular change, like the power transmission between the gem vortex motor and the motor that my mother is doing now uses gear transmission, and the mathematical prime number is also used in the gear design. to find the number of gear teeth and gear angle with the least mechanical loss and failure rate. ”

Listen to Li Yuanling talk about the important application of mathematics in industrial production. Liang Yuan sighed secretly, and said in his heart that future generations will not know which 2b brain-dead college entrance examination will cancel mathematics, and what is the use of the waste college students who can't even learn basic mathematics in society? Sing a song. Filming a movie or something is much richer than going to college. Why do you have to squeeze the college entrance examination with a dead face.

No wonder the Republicans in the United States have never looked down on the so-called masses, and the ass always sits on the side of the elite, for part of the ignorant masses. From the point of view of the ruling class in the United States, the meaning behind the so-called "Lamb of God" in the Western proverb is deeply terrifying.

Li Yuanling looked at Liang Yuan's gaze wandering, first pinched Liang Yuan's cheek, and then suddenly felt that he had entered a professional state again, and said with a somewhat self-deprecating smile: "Mom has pulled things away again, but as far as the intercooling and reheating device is concerned, the simple understanding is to make a large heat dissipation area in the smallest space, and in the face of the high-temperature exhaust gas of the gas turbine, the traditional pipeline exchange radiator can not meet the requirements at all in terms of volume efficiency, and can only use a new plate-fin radiator." ”

"According to the principle of thermodynamics, under the same conditions, the larger the surface area of the object, the faster the heat exchange, so in terms of the performance of the plate-fin radiator required for the gas turbine, it is necessary to reach a minimum of 5ooo square meters of heat exchange area in a cubic meter of space, so as to have practical value in engineering, if you want the outlet temperature of the unit exhaust to drop to about 2oo degrees, the heat exchange area must reach 15ooo square meters, in other words, it is equivalent to stuffing the surface area of two football fields into a cubic meter of space, during which a large amount of medium responsible for heat exchange also needs to flow quickly, Xiaoyuan said that this kind of thing is difficult or notLi Yuanling looked at the stunned Liang Yuan with a smile.

Liang Yuan has already heard stupidly, no wonder the current United States is fond of the development of simple cycle gas turbines, the difficulty of this intercooled reheating device is simply against the sky, Liang Yuan does not know that the world's Taiwan uses intercooled reheating device high-power marine gas turbine unit R21, in 1991 to start the research program, with the cooperation of Britain, the United States, and Canada, it took 10 years to successfully develop.

"That's why my mother told you that the computer is the foundation of future scientific and technological research, such as the thermodynamic conversion and fluid flow design of the intercooling recuperation device, which has completely exceeded the limit of human calculation. ”

Listening to Li Yuanling's emphasis on the importance of advanced computers again, Liang Yuan felt deeply that the United States in the future relied on its leading position in the semiconductor industry to gain a huge advantage in mathematical calculations, detonating the third industrial revolution in human industrial history after the collapse of the Soviet Union, and further growing into the only major power on the planet.

If it weren't for the fact that the nature of the capitalists was too greedy, which led to the hollowing out of industries in the United States, the republic would have had no chance of rising a few decades later.

Liang Yuan followed Li Yuanling in the science and technology park for a long time, to get a lot of real surprises, nearly a year Liang Yuan's main energy is on the F14 fighter jet and the battle of Nansha related to the future of the republic, every time I come to the science and technology park is in a hurry, today I took a closer look before I felt that there has been a great change.

Include fixed investments such as equipment and plants. The entire Nanhu Science and Technology Park burned at least 1.5 billion yuan throughout the year, and Liang Yuan's world's allocation of funds, in addition to the necessary working capital, the rest of the group was basically invested by Liang Yuan in the Science and Technology Park and Changbai Island.

At this time, the science and technology park is no longer a slightly shabby appearance when it was first created, under the shade of a green pine and cypress, eight or nine large steel structure buildings or blue or white are scattered among them, the blue ones belong to the gas turbine room, and the white ones belong to the electronic room.

Originally, it also occupied a large area in the science and technology park, but Zhu Liguo moved most of his belongings to Benxi, and only three or two big cats and kittens were left behind on the Nanhu side.

Over there in the electronic real yàn room. Su Liangyu and others put resources in terms of construction. All of them have been invested in the construction and renovation of two 5-micron production lines, and the infrastructure of the gas turbine room is blooming everywhere.

Since the problem of the life of high-temperature resistant metal materials has not been solved, the scientific research task of the gas turbine laboratory this year is not heavy, and Li Yuanling has taken out part of his energy to build a large number of civil works. A series of test benches for testing various types of gas turbines have been built.

In the process of research or improvement of aviation motivation. Testing equipment is crucial. The simplest example, without a large-sized pitch stage, it is simply impossible to develop a qualified turbofan jet motor. For example, Japan in later generations has reached the world's top level in some heat-resistant materials, but even the independent development of a small turbofan aviation motor is tantamount to a dream.

Some time ago, and the first batch of gem vortex motor arrived together, in addition to some technical data, the rest is all the relevant test equipment of the motive, because the plant and other hardware facilities have already been built, it took only two weeks to a stone vortex motor testing line that is 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 locomotive can get a clue in a short time, Li Yuanling's forward-looking planning has contributed a lot.

A few people walked around and talked until it was dark before leaving the science and technology park to go back to the 9o9 community for dinner, after dinner, it was already more than nine o'clock in the evening, Li Yuanling did not let Liang Haiping's family of three go to the hotel, and drove Liang Yuan to the living room on the sand to deal with it overnight, Liang Haiping's family lived in the bedroom where Liang Yuan usually sleeps.

The next day, Liang Jiangping and Li Yuanling, who had no other affairs for a long time, took Liang Yuan back to Benxi, where they hadn't stayed much this year, until Liang Pan rarely caught his brother's figure, and followed Liang Yuanfang like a little tail, someone had to make a cameo appearance with the children's business, and accompanied Liang Pan to play all day in the crowded department store and the children's park that had been there countless times.

February 5 was the traditional Chinese New Year's Eve of the Republic, and Liang Yuan, who had nothing to do, had a rare lazy sleep, until it was nearly noon, when he was woken up by a call from two little girls from Beiping, lying on the bed and talking nonsense for more than half an hour with the two little girls who were about to leave the Loli era, before being forced to get up and wash by Li Yuanling with his ears.

For Liang Yuan, who is accustomed to living in the information age, the idle days of the 80s seem to be extremely difficult, there is no mobile phone, no tablet, no Internet, no money or not, the main activities of Chinese New Year's Eve are to prepare for a reunion dinner, prepare dumplings and watch the Spring Festival Gala.

As soon as the sky was dark, the phone on the sand in the living room began to ring non-stop, both Liang Jiangping and Li Yuanling were the heads of the unit, and those with eyes knew that the peak hours of New Year's greetings in the middle of the night always had to leave private free time for the leaders, so they called in early to call in for the New Year's greetings.

Listening to the phone ringing endlessly, Liang Yuan said with a smile: "I just counted it, and there are more people who call to find Dad, it seems that Dad will go to the unit to work overtime during the Chinese New Year next year, so that the family can stop a lot." ”

At Li Yuanling's strong request, Comrade Lao Liang had a rare New Year at home this year, and did not go to the unit to inspect and work overtime.

Liang Jiangping laughed when he heard Liang Yuan say this: "Sure enough, it's a big deal, you think I don't know your ghost thoughts, are you afraid that Beiping's phone won't come in." ”

With the thickness of Liang Yuan's face, this kind of Cheng Dù's ridicule was naturally immune, and he spread his hands lightly, making a rogue expression that you can say.

"Xiaoyuan is still young, in a few years, I'm afraid Xiaoyuan will be the busiest person at this time. Liang Haiping also said with a smile.

On weekdays, Liang Yuan's business excellence is very easy to forget about Liang Yuan's age, but when it comes to the New Year, this problem is particularly prominent, such as Qi Lianshan, Liu Wenyue, Su Liangyu, Zhou Yuanhang and other core management personnel who know Liang Yuan's details in the past year all laughed and talked about it, saying that they would discuss a unified time period on Chinese New Year's Eve and go to call Liang Yuan to pay New Year's greetings together, so as not to inadvertently destroy the boss's low-key plan.

Finally, Liang Yuan had the heart to deal with this group of middle-aged and elderly people, and strongly vetoed the mention of a group of managers, so that Liang Yuan could be considered free, otherwise he would have the opportunity to lie in bed until noon during the day.
