In the dark night sky, countless pieces of snowflakes are falling freely, because there is no wind, the snowflakes are falling lightly, silently like a goddess scattering flowers, the distant mountains, the nearby houses and trees are decorated with a layer of pure plain white, all in all, as long as anything exposed to the sky can not escape the coverage of these cold crystals, whether it is the only bright street lamp on the road of the Central Plains Electronic Radar, or the bench under it or Lu Jiadong, who is sitting in the corner of the chair, leaning on the back of the chair, looking at the dark sky and smoking a cigarette！

Lu Jiadong has been sitting here for a while, the military cotton hat on his head and his shoulders have long become snow-white, because he can't sleep, so Lu Jiadong came out for a walk, thinking about breathing the cold air outside to relieve his anxiety.

I don't know if it's because the winter in the Central Plains is not too cold, or because the snowflakes in the sky make people think more, Lu Jiadong's thoughts have not calmed down, but several questions about computers that he talked about with Liu Haotian and Li Ming an hour ago have always lingered in his mind:

"Now that the DJP-140 computer can reach the level of practical use, it should be boldly used and build the radar first. ”

"Computers are important, but our progress is more important, so the performance improvement of computers can be put on the back burner!"

"Xiao Lu, the road has to be taken step by step, the meal has to be eaten one bite at a time, the development of radar is like this, and so is the computer!"

"Xiao Lu, we understand your high standards and strict requirements, but you also have to face up to the actual situation in front of you."

Liu Haotian and Li Ming's words were constantly playing in Lu Jiadong's mind over and over again like a slideshow, in fact, Lu Jiadong knew very well what Liu Haotian and Li Ming meant, although the high-level and the General Staff Department did not specify a strict timetable for the completion of artillery radar, but as people involved in the development of artillery radar, they all knew in their hearts that this kind of front-line troops urgently needed to break the monopoly of foreign technology and equipment, the sooner the development was completed, the better.

Because of this, most of the domestic mature technology and manufacturing processes are used in the formulation of research and development plans. The main reason for this is to save time, and Lu Jiadong did not raise much objection to this development idea, because he also knows that time is precious, but since he saw the actual DJP-140 computer during the day's research. Lu Jiadong's mind changed slightly.

Zhong Xiaomo's telegram did not give a detailed description of the specific parameters of the DJP-140 computer because of the number of words and secrecy, but only mentioned that it was small, and when Lu Jiadong saw the real thing, he learned that this so-called "small" computer was also more than half a person tall, and its vertical rectangular structure was about the size of the large shoe cabinet of later generations.

Not only that, because of the backwardness of the country's semiconductor processing technology. The circuit structure inside is extremely complex, the calculation speed is increased, but then the power and weight are multiplied and the reliability is reduced, according to the introduction of Zhongyuan Electronic Radar Factory, the average failure time is almost 100 hours.

Not to mention the leading group for the development of artillery radars, even the Naval Research Institute, which was the first to support the development of modified computers, was very dissatisfied; it was precisely for this reason that, at the urging of Lu Jiadong, the two departments agreed to work together to improve the DJP-140 computer, but the focus of the improvement was on reliability and standardization.

Lu Jiadong hopes to further improve in miniaturization and performance optimization. You must know that a computer of this size is nothing to put on a ship, after all, there are many cabins of large ships, and the security space of the platform is abundant, but the artillery radar is different, such a "big shoe cabinet" The cooling system is very complex, if you add the display system, scanning system, antenna system and other parts of the radar, then the weight of the whole set of artillery radar must reach several tons, and such a weight is unimaginable for the artillery radar that advocates high mobility and rapid deployment.

To this end, at the evening seminar. Lu Jiadong also put forward his own idea, but there were few applicants for no other reason, mainly because the development of computers is also a long-term project. Although miniaturization and performance enhancement are simple to say, they involve all aspects of the computer's internal work, and it can be said that it is equivalent to overturning the entire DJP-140 computer from the ground up, and no one knows when it will be successfully developed, perhaps in three or five years. Or more than ten years, no one can give an exact time anyway.

It is precisely for this reason that on the premise of ensuring the overall development progress, most people tend to choose the DJP-140 computer, which is relatively mature at present, and even Li Ming of the navy, which has a long period of equipment development, holds a similar viewpoint, and Lu Jiadong is also very clear about this, and he understands the reason for solving the problem first, after all, in the current state of technology, the relevant technical verification and accumulation and the solution of the current problem are the most important.

However, if there is a problem that can be solved, does it mean that the follow-up improvements can be carried out smoothly? The Yun-10 aircraft solved the problem of whether or not the large aircraft existed, but then it was tragically dismounted; the nuclear submarine solved the problem of whether or not it was not, but it was stalled for nearly 10 years before restarting the relevant program; there are many similar examples.

Lu Jiadong, as a military industry expert who traveled through the later generations, sighed every time he saw similar information, and whether there was a problem or not was not worth showing off, and only when it was transformed into a real weapon in the hands of the troops, could he have the capital to stand up, and it was precisely because of this that at the beginning of the development of artillery radar, Lu Jiadong put forward the overall requirements of practicality and actual combat.

But now the performance of the unsatisfactory computer has become a roadblock, and the integrated circuit manufacturing, processing technology innovation and the construction of the talent team involved in it, each of which is a time-consuming and labor-intensive system engineering, especially in the construction of the talent team, as the saying goes, ten years of trees and a hundred years of people, the domestic electronic talent in this area is in short supply, not to mention the relevant skilled workers with rich experience, so that it can not be solved overnight!

Thinking of this, Lu Jiadong sighed deeply, whether to give up appropriately, or try to achieve both fish and bear's paws, whether to compromise or continue to insist, under the contradiction, Lu Jiadong took a few puffs of smoke, and then spit it out deeply, the turbulent air flow turned into white smoke in the cold air, blowing the snowflakes falling step by step in front of him into messy flying, just like Lu Jiadong's mood at this moment!

"Alas! what a hard bone!"

Lu Jiadong sighed, and walked aimlessly along the path, his thick cotton shoes made a "creaking" sound on the ground covered with snowflakes, and he didn't know how long he walked, a row of low bungalows appeared in front of Lu Jiadong, except for the bright lights in the middle, the others were all dark.

Seeing this, Lu Jiadong knew that the scientific researchers of the Central Plains Electronic Radar Institute were working overtime, so he stood still and looked back, only to realize that he had walked so far unconsciously, and then raised his arm and looked at the watch in his hand by the light from the room not far in front, only to find that the time had passed half past ten!

"It's so late, I have to go back and rest!"

Lu Jiadong muttered to himself, put down his arm, and then turned around, but before he could raise his leg and prepare to leave, he heard a familiar voice faintly from the brightly lit room:

"Xiao Song, do you know that improving the computer is easy to say, but it is really a difficult bone to gnaw!"

When he heard the two words "computer" and "hard bones" that kept appearing in his mind, Lu Jiadong couldn't help but be stunned, and then stopped, and at this moment, a stubborn and energetic voice sounded again:

"Teacher, I'm not afraid of being bitten hard, you see Director Lu Jiadong Lu, he has this achievement at such a young age, isn't it also a hard bone to gnaw down, what can he do, what can we do?"

Hearing these words, Lu Jiadong couldn't help but be stunned, and then Zhong Xiaomo, director of the Central Plains Electronic Radar Institute, and his protégé Song Xiaoxu came to mind, and in fact, it was true, the people in the bungalow were none other than Zhong Xiaomo and Song Xiaoxu, because the scientific research conditions of the Central Plains Electronic Radar Institute were limited, and the only office building was used for the storage and experiment of precision instruments.

So the daily office is still in this low bungalow, at this time Zhong Xiaomo and Song Xiaoxu are working overtime here to calculate several basic calculation formulas of artillery radar, just after the two of them completed a demonstration, Song Xiaoxu once again put forward the dream of developing a computer in his heart.

You must know that since he was admitted to the Department of Electronic Engineering of Tsinghua University, he was determined to develop a high-performance computer by himself, for which he made similar requests to his mentor Zhong Xiaomo more than once, but Zhong Xiaomo rejected it every time, and the reason for this Song Xiaoxu is also very clear in his heart, the chip is not up to standard, the circuit is old, and the process is backward.

Because of this, Song Xiaoxu hid this dream in his heart, and now Lu Jiadong has brought a large number of high-performance chips such as 8088 to the Central Plains Institute, which once again ignited the hope in his heart, and is more determined than ever, but his mentor Zhong Xiaomo is still the same, after all, Zhong Xiaomo has a down-to-earth and steady attitude in addition to enthusiasm, and he knows very well that it is not easy to improve and develop computers, because of this, when Song Xiaoxu's voice just fell, Zhong Xiaomo said:

"China is just such a Lu Jiadong, the weapons and equipment he makes are supported by a mature industrial base, and we" said Zhong Xiaomo shook his head helplessly: "The conditions and the foundation are still far away!"

"Knock~~~" As soon as Zhong Xiaomo's words fell, he heard a knock on the door, and then a flat and familiar voice came from his ears:

"Mr. Zhong, can we have a deeper discussion on this issue?" (To be continued.) )
