How to decide within the 617 factory, Liu Yue and others don't know at all.

During the Chinese New Year, when such a thing happens, everyone is upset.

Even if Wei Guiping and the others said that there was no problem, and Zhu Dingguang said that there was no problem, Liu Yue was still a little reluctant in his heart, and he hit 3 improved 69 tanks, and he didn't know if it was Type 69-2.

Anyway, he knew that the tank could not be tested.

Regardless of the 617 test team, they need to solve their own problems.

Even if it's New Year, the work continues.

Ye Xin went to the physical and chemical laboratory early in the morning to compare the difference between the 8701 they produced and the 8701 in the 617 armor-piercing bullet.

The people of 617 looked at them with hatred on their faces, but they didn't make any drastic moves.

Before noon, the results were in.

"The problem is in the charge, the internal chemistry of the 8701 we use is different from that of the 8701 of other units...... The information is all here...... "Ye Xin brought the formula and production materials produced by the base.

These data have been compared countless times before, and there is no problem with other productions.

"What caused it?" Wei Guiping and others wanted to figure this out.

If it is solved, production can continue in the base.

"I don't know, our production process is no different from the production process of other units, and all the formulas are the same. Ye Xin shook his head.

She couldn't find what the problem was.

The problem was found, but what was the cause of the problem could not be found.

Everyone is comparing data and trying to find the crux of the problem.

"These components have changed during storage, and according to chemical analysis, it is caused by too much acidity...... Ye Xin explained to everyone.

Liu Yue suddenly raised his head: "Caused by water in the production process?"

"How is it possible!" Everyone was incredulous when they heard Liu Yue's proposal.

"All the raw materials, formulas, and production processes, there is no problem, but the 8701 we produce is different from the 8701 used in the 617 The water used in the production process is different...... Liu Yue explained his reasoning, "The water in the north is much more alkaline than the water in the south, and the alkali can synthesize the acidic ...... inside the explosive."

"This is unlikely, right?" Liu Yue's proposal sounded very reasonable, but Ye Xin felt that it was not very likely.

There is indeed a gap between the north and the south in the alkalinity of the water, but it will not be so large.

"You can immediately shoot the telegraph base and analyze this...... If this is really the problem, all the rocket shells with 8701 charges produced in the base before have problems......" Liu Yue is sure that it should be caused by such reasons.

He suddenly remembered that he had watched a talk show that belonged to history for their time, and in the middle there was an introduction to the development of domestic high-energy explosives.

And the interview with Academician Xu Gengguang, a charge expert, also made Liu Yue deeply memorable.

I didn't say it before, because they didn't use the original 8321, but the 8701 that solved the problem of high internal corrosion of 8321.

Now Ye Xin said that it was caused by acid, which corroded the entire explosive, Liu Yue suddenly remembered that Academician Xu Gengguang said in the interview program: 8701 because of the difference in alkalinity in the production water, the water used in the south is not as alkaline as the north, and the internal stability is much worse, and then a special stabilization system was developed to make the entire 8701 more stable......

That is, this problem was solved, and finally 8701 was the main charge of various domestic weapons for a long time.

It was also the largest manufacturer of PBS viscous explosives in China for a long time.

"Why don't we go to Professor Xu?" Ye Xin asked Liu Yue, "If it's because of the alkali in the water, the reaction is not so fast." At low temperatures, the reaction will be slower......"

As an ammunition expert, Ye Xin could not accept Liu Yue's proposal.

Is it just that there is a slight difference in the amount of water used in the process that causes this?

"In the past, in the production process, it was a high-temperature steam charge, and most chemical agents, the higher the temperature, the faster the reaction speed...... And before that, the reaction may have already begun to accelerate. These explosives are not first produced and loaded directly into the rockets, but are produced for a period of time and then reheated and reloaded......"

Liu Yue felt that there was nothing to doubt about this.

"Now that the problem has been identified, prove it with evidence. In this way, let's rest for a day today, and set off early tomorrow morning, and you go to Professor Xu......" Wei Guiping said to Liu Yue and the others, "We are here, change all the charges inside, and continue the test." ”

Liu Yue has no objection to such an arrangement.

It just so happened that he could drop by to see his teachers.

What's more, he needs to turn in his homework!

They also have to complete their first semester of graduate school exams.

According to the original agreement, he had to go back to take the exam after New Year's Day, but he worked on a project at the base, contacted the teachers, and was asked to solve these problems before the start of school.

"Let's rest for a few more days, I just came, and I didn't have a good rest......" For Liu Yue and his party to leave so quickly, even if they knew that the conditions here were not good, Zhu Dingguang also hoped that Liu Yue and them could rest for a few more days, "The people of 617 have already left. ”

"If they don't leave, it's a waste of money to stay here. Lao Zhu, it is estimated that we will come for a lot of time in the future, and when the time comes, I will bring you some good wine from the southwest and drink a few cups......" Yan Heping admired Zhu Dingguang very much.

Zhu Dingguang just wanted the group to rest more, and on the way to and fro, it took a long time and tortured people.

Now that it has been decided, Liu Yue and his entourage began to pack up all kinds of materials.

The data from the trial here also needs to be brought back.

At 3 o'clock in the morning, Liu Yue and his party got on the hand-cranked liberation car in a low temperature of more than minus 40 degrees.

"This thing, it's really time to be eliminated, it must be at least thirty years old......" Yan Heping looked at the car and sighed.

Zhu Dingguang was beside him and said with a smile: "It's not as exaggerated as you say, it's only been 23 years since the first Jiefang car rolled off the assembly line." ”

After speaking, he handed Yan Heping a bag wrapped in oiled paper.

Yan Heping took it, and it was still hot.

"Roe deer meat, eat it on the road. ”

Without much explanation, the car was already in motion.

"If our base is here, it is estimated that there will be no such thing within a radius of dozens of miles......" Liu Baojun was in the car, took the roe deer meat that was still hot, and said happily.

"I didn't give our test team a ...... for the New Year," Liu Yue was a little puzzled.

"I caught it in the snow yesterday. Yan Heping didn't explain much.

He didn't say that this was because he himself saw that the living conditions of his comrades were too difficult, and he and Zhu Dingguang carried 107 rocket launchers and searched in the snow all day to fight.

I can't say anything about this.

The return journey is the same distance as the way they came, but everyone is getting more and more relaxed, even if the temperature still hasn't changed much, everyone feels that the journey is much closer.

"Too much time was wasted along the way. ”

Liu Yue was a little resentful of this era, even if he didn't stay, on the way back, when he arrived in the capital, it was five days later.

Although the year is not over yet, the people of the entire capital have already put themselves to work.

The two got off the train and went straight to Polytechnic University, but fortunately, Ye Xin was familiar with his professor, and he didn't go to the professor's house for dinner.

When I arrived, I found that there were countless people queuing up to pay New Year's greetings to the professor......

"Why are you here together?" Professor Xu Gengguang has a deep memory of Liu Yue.

Ye Xin was his student, and he was familiar with it.

But Liu Yue and Ye Xin came to visit together, which surprised him a little.

"Professor Xu, our project has encountered some problems, 8701 has the same production process, formula, but the final result is different, Comrade Liu Yue suspects that it is caused by the alkali content in the production water...... "After greetings, Ye Xin went straight to the point.

There are a lot of people who have come to see the professor these days, various relevant military industrial units, and the professor's students.

The two of them finally waited until the professor had some free time, so naturally they couldn't waste it.

"Is there such a thing? Professor Xu Gengguang was not displeased with Ye Xin's proposal.

When Ye Xin introduced the situation, her brows were wrinkled together.

He hadn't thought of such a question before.

Since its introduction, 8701 has undergone countless trials and has continuously improved its formula to make it more stable.

Seek to achieve a balance of all chemicals.

"Have you brought any samples? Let's go to the laboratory......" Professor Xu directly proposed to go to the laboratory for testing, regardless of the other guests and other arrangements.

Samples, Ye Xin and Liu Yue must have brought them.

"Lao Xu, ...... in a while"

"It's important to solve the problem first. Ignoring his wife's reminder, Professor Xu took the two of them directly to the laboratory.

Liu Yue rarely spoke.

On the way to the laboratory, I wondered if I should ask Professor Xu if the aluminum-containing explosive 8702 he studied had completed all the finalization tests.

He originally proposed to add aluminum powder to the explosives, which led to chaos in the classroom, although Ye Xin had said before that Liu Yue did not think that the finalization test had been completed.

"You proposed to add aluminum powder to 8701 before, the power can indeed be improved a lot, and the current formula is also becoming mature......" On the way to the laboratory, Professor Xu took the initiative to speak to Liu Yue.

"Professor Xu, I was also whimsical at the beginning, I didn't study ammunition-related majors...... Liu Yue didn't feel the slightest embarrassment, "Whether aluminum powder can effectively improve the power of explosives, I didn't know ...... at that time"

"To engage in scientific research, we must dare to think and experiment. It's a pity that you are not a major in ammunition science, and the field of ammunition science needs young people like you. Compared with the rest of the world, our domestic explosives are still far behind...... "Professor Xu regretted it.

Liu Yue didn't say anything.

Ye Xin was about to introduce Liu Yue's situation to the professor, but when he saw that Liu Yue himself didn't say anything, he didn't say anything.

Although it is only the seventh day of the Lunar New Year, the laboratory of Polytechnic University has entered a normal working state.

When Professor Xu arrived at the laboratory, he did not pay attention to Liu Yue, but personally went to test the samples brought by Liu Yue.

These samples were used in the rockets originally produced at the base.
