Chapter 242: Bottom-line thinking in key technologies
“So...Dr. Chang, you already have a plan in this regard?”
Xu Yang’s voice was a little dry, but she had already taken care of it. Not that much anymore.
If the idea just mentioned by the other party can come true, it will definitely trigger a major earthquake in the field of numerical computing applications.
“We can’t talk about the plan yet. We can only say that we have some preliminary ideas. We are still a little far away from the plan. We need to fill in some theoretical and experimental gaps.”
Chang Haonan shook his head. Even with systematic help, he would not be that awesome.
This should be a somewhat lengthy, step-by-step process.
After all, if he alone, or a few people around him, conduct experiments and collect data, then he may not be able to optimize what he wants in the next life.
So the wiser choice would be to create the most basic version first, and then rely on the strength of the entire industry to provide feedback and upgrade step by step...
It seems like before he was reborn. Some car companies have similar ideas.
New car launches are all cake, and all features have to wait for OTA.
Ahem...
In short, although there is some controversy in the cycling circle, the routine itself is not problematic.
As the functions of software become more and more complex, it is gradually becoming unfeasible in terms of technology and cost to release a so-called "complete version" in one step. Instead of forcing a version with comprehensive functions but poor reliability, For semi-finished products, it is better to focus on polishing a few specific modules first, and then gradually expand after gaining users and reputation.
And he just borrowed a little bit from the Internet thinking more than twenty years later.
"Numerical simulation of multi-physics coupling is still a blank in the world. As far as I know, only a few schools have some very simple tool kits. If a breakthrough can be made in this area, it will definitely be possible." A major event that affects the entire industry!"
Xu Yang looked at Chang Haonan beside him with bright eyes.
“This is true, but the first step is to be down-to-earth.”
Chang Haonan expressed his thoughts:
“First of all, we need to understand the heat transfer phase change and structural mechanics. , fluid mechanics, and electromagnetic fields, as well as weak coupling problems involving 2-3 physical fields such as convection diffusion, convective heat transfer, thermoelectric coupling, and fluid-solid coupling, and then gradually overcome them. Problems with more physics and stronger coupling ”
"But if that's the case..."
Xu Yang frowned slightly when he heard this:
"Dr. Chang, you should also know that almost all single-physics simulations have now been There are relatively mature solutions, and weak coupling problems with low nonlinearity can also be solved through brief coupling or full coupling. I am afraid that they will not be very attractive to new users..."
Of course what she said makes sense.
People are all inert, and they will remain unchanged if they can.
This is especially true in the engineering field.
Before Chang Haonan was reborn, there were even some engineering software that had not been updated for many years and only supported Windows 98 system, so that their research institute had always kept an old computer that could be called a cultural relic.
But the problem is that, similar to the situation with civil aircraft airworthiness certification, if you don’t seek changes now, and you want to do the same thing again in the future, the price you pay will be a hundred times a thousand times.
Chang Haonan, who has experienced this once, knows this very well.
On the one hand, it is early 1997. Although the relevant industrial software in Western developed countries has been developed for about 20-30 years, it has just begun, or has not yet begun to think about commercialization. Everyone reluctantly We are still at about the same starting line.
On the other hand, in China, only universities, research institutes and state-owned enterprises that use commercial software extensively in China are places that can be reached by administrative orders, and the relevant software ecological barriers have not yet been established.
In fact, China's own semiconductor industry and software industry were not established very late. They had already improved in the early 1980s. The gap with Neon is about 5 years. Although it is not It is considered advanced, but it can also be regarded as forming its own industrial system.
However, like many industries, the budding signs of development have been suppressed.
Without top-down support and without a mature business model, scientific research, education, and industry were quickly isolated.
Hardware manufacturing plants have become assembly lines that provide cheap labor for foreign companies, and the software industry has completely become a vassal of others. A large number of software engineers who originally developed software independently have become ordinary low-level code farmers. .
Only some research institutes and schools are left to continue research, but they are also unable to support themselves. After losing their ecology, they are increasingly disconnected from actual production.
It was not until more than twenty years later that due to various reasons, we finally paid attention to this aspect again.
In fact, a similar situation also occurred with Maozi after the disintegration. In 1990, Mao Xiong's electronics industry was probably equivalent to the level of the United States in about 1985.
But by 2000, they were still stuck at the level of Americans in 1985, and completely missed the explosion of the information industry in the 1990s (actually it was even worse, because they couldn’t even follow other people’s standards) no chance).
It was also more than 20 years later, due to sanctions, that the industry was revived. By that time, it had already lagged behind the advanced level for many years.
In short, it was difficult for people in 1997 to understand the bitterness and sorrow involved.
For Chang Haonan, who was reborn, it was not too late to make amends.
He really doesn’t understand anything about semiconductors now, so let’s start with industrial software.
“If we only consider it from a technical perspective, Researcher Xu is right.”
Chang Haonan used a more euphemistic expression. After all, no matter how talented a person is, it is difficult to transcend the times. It is normal to have the kind of thoughts just now.
Xu Yang could naturally hear that Chang Haonan had different opinions from hers, but considering the other party's ability, she just showed a somewhat curious expression:
"But things like industrial software , It is not entirely a technical problem, otherwise there would be no such thing as the Wassenaar Agreement.”
“Now that we use foreign software, we really don’t feel any inconvenience except the language barrier, but That’s because a lot of software has not been commercialized yet, or is in the process of expanding the market in the early stages of commercialization. But if these foreign companies continue to attack our country unscrupulously, the future will be uncertain.”< br>
“Right now, everyone’s starting point is pretty much the same, but the information industry is developing too fast. The more users an industrial software has, the more information feedback the developers will get, which will lead to greater quantity and quality. Higher databases will allow us to develop more useful data models. If we cannot keep up with this step, we will not be able to keep up with each step. If one day in the future, some industrial software suddenly appears in the Wassenaar Agreement, At that time, if we want to start from scratch and accumulate data, it will be more difficult than reaching the sky. ”
The powerful words made the atmosphere around the entire table become a little heavy.
Xu Yang, who had been a little unimpressed just now, his pupils trembled sharply after hearing this, as if he had seen a new continent.
She would choose to return to China from the United States in the early 1990s, and she naturally had no shortage of feelings for her family and country.
But many things are not just about feelings.
The struggle on the scientific and technological front is also a struggle, and it requires a skill and strategy.
In this regard, obviously no one can compare with Chang Haonan, who has experienced the trade war era.
“Actually, we have made a breakthrough in the export of industrial software.”
Looking at the people who were lost in thought, Chang Haonan once again dropped a bombshell.
Anyway, everyone sitting here has sufficient authority.
“Industrial software...export?”
Xu Yang, who was outside the aviation industry system and had no idea about China's negotiations with Europe, felt that for the first time in his life, his mind was a little out of control.
You must know that China's software industry is still at a stage where it is not clear how to localize the UI interface.
Why was it exported?
Chang Haonan nodded:
“Yes, a small software that predicts the icing probability and ice type of aircraft in humid and cold environments is not our first creation, but its functions are definitely better than those of foreign countries. Any competing product is better and sold to Europeans.”
"This shows that as long as we can create unique functions or features, we can completely defeat others in the software field!"
In fact, considering this was at the dinner table, he still had half a sentence left to say. ——
Anyway, the performance of our products now relies on defense. Even if what we make is a defense, as long as it is made into chocolate flavor, some people will pinch their noses and eat it.
At this time, on the other side of the dinner table, Sun Cong, who had just been listening to the conversation between the two, suddenly said:
"I have heard about this matter, but I have never been sure whether it is hydrated or not. , now that Comrade Xiao Chang has said it, it is indeed a huge breakthrough..."
With the praise, Chang Haonan naturally accepted it:
“Of course, this time we have indeed taken a rare opportunity to create discord between Europe and the United States. No one can guarantee that other software will be used later. There can still be such a good response internationally. ”
“However, what I want to say is that in terms of industrial software, including but not limited to, we must have bottom-line thinking and cannot let others control us. Neck!”
