Chapter 138 Nitrocellulose!

"How is the situation regarding the Japanese army's deciphering of telegrams?"

"Comrades from the communication department are working with Comrade Teko to obtain information and translate at the same time. We have found a comrade who has knowledge of matrix theory. He will arrive at 1:10 in the morning, that is, [-] hour later, and it is expected to be around [-]:[-] tomorrow morning. Can decipher the first Japanese military telegram."

"Okay, this is a very good job. I hope to see the results as soon as possible. In addition, the notebook was sent by our Comrade Qingluan at the risk of our lives. We must treat it with caution and never allow any mistakes. High confidentiality with the notebook, and the level has been raised to top secret."

"Yes!"

When the male secretary who was in charge of reporting the current situation left, there were only three people left in the house.

The middle-aged man, codenamed 'Professor', sat upright, took out a pack of cigarettes in his right hand, lit it up, and exhaled a puff of smoke: "It is initially confirmed that this Japanese red secret deciphering material is true, and it is extremely useful for our anti-Japanese work. Great help, according to the contents of the second letter submitted by Comrade Qingluan, it can be determined that Mr. Zhang San has worked for the Secret Service of the Blue Clothes Society and has a close relationship. In order to protect the safety of Mr. Zhang San, I think the red secret should be The deciphered information is listed as the highest level of top secret, and the disclosure of information should be avoided as much as possible."

The cost of leaking information is extremely heavy. The Japanese will not only update the password system immediately, but will also frantically search for Zhang San.

But it's not over!

The Secret Service of the Blue Shirts will immediately start an investigation of the personnel involved in the deciphering of the red secret, which will greatly increase the risk of Mr. Zhang San's exposure.

For the safety of Mr. Zhang San, as members of the Eighth Route Army, there is only one thing they can do - keep it secret.

Keep it as secret as possible!
"Agree, this Mr. Zhang San risked his life to leak this complete information to us, we can't put him in danger, he is our friend." Another middle-aged man nodded, with a serious face, Hubei The tone of the accent contains solemnity.

The last person said: "Agree, but I think that Mr. Zhang San should be looked for. I can feel that he is full of goodwill towards our organization and agrees with us very much. To have such an expert who can decipher the Japanese military code system join us. The team will be stronger.”

An expert in deciphering the Japanese military code system!
Most people may not understand this concept.

But anyone with a little knowledge of the situation can see how precious this type of expert is.

This is not simply stealing intelligence, but a full-scale attack on the enemy's communication system.

"I have arranged for people to search for this, but I don't have much hope. Regarding the first matter, everyone will raise their hands to vote." Hearing this proposal, the professor shook his head slightly, changed the subject, returned to the topic, and raised his right hand to express his position. .

Immediately afterwards, the two middle-aged men sitting on both sides of the dining table raised their right hands one after another.

3:0, unanimously approved the plan of 'listing the red secret deciphering materials as the highest top secret level'.

The confidentiality level is divided into the highest top secret, top secret, secret, and secret. The secret level is determined according to the value of information and items. The confidentiality period is 50 years, 30 years, 20 years, and 10 years respectively.

The professor who is the top leader of the Northern Organization can independently determine top-secret information and items, but the classification of 'top-secret' must be determined through discussion at the organization meeting and follow the formal process.

For the Eighth Route Army, the value of this extremely precious and complete red secret deciphering material has reached the highest top-secret level, and it is not very helpful to the anti-Japanese work.

Know yourself and the enemy, a hundred battles will never end.

Before the Japanese discovered that the cipher system had been deciphered, the contents of Japanese diplomacy and Japanese army communications would be completely mastered by the Eighth Route Army.
Although, this situation may not last for too long, about three months, maybe half a year, of course, the Japanese army can change the password system on a whim tomorrow.

As for the Japanese Navy, I can't control it for the time being.

"Second thing, Lin Wan, the head of the youth organization Beiping No. [-] Middle School, codenamed 'Qingluan', risked her life to send the notebook to the organization safely. I think Comrade Lin Wan should be credited." The professor paused and continued. said.

"I agree. Comrade Lin Wan has an excellent performance, she is smart, she once participated in the [-] Movement, and she is a rare outstanding lesbian."

"I agree."

The other two nodded.

"Okay, the meeting is here for the time being. Comrades, with this precious information sent by Mr. Zhang San, I believe that we will definitely win the final victory."

……

Since the privileges given by Mr. Ren Luo Wenguang in the classroom, Yu Hua's academic level has been rising recently. Mathematical analysis has really started. He has mastered all kinds of elementary mathematics knowledge and advanced mathematics knowledge, and has a deeper understanding and further improvement. scientific ethics.

Mathematical analysis has something that distinguishes it from all sub-disciplines, that is, the mathematical thought that goes back to its origin.

With the higher and higher academic level of the main subject, Yu Hua's future plans and goals have become more and more clear. At the same time, the final structure of the thinking finite element analysis system is constantly being constructed, and the total progress has reached 78%.

There is only one step left to formally establish the initial thinking finite element analysis system.

The sky is clear and cloudless.

In the late spring season, the city of Peiping has been enveloped by the greenery that symbolizes hope, and freshly drawn tender strips are everywhere.

Xicheng District, a small chemical laboratory, the first experiment to produce nitrocellulose is in progress. Yu Hua is standing in front of the operating table with a grim face. While conducting the experiment, he records the entire production process in detail. Standing next to him is Xu Rui, who acts as an assistant. .

Although Xu Rui's basic literacy was not up to standard, Yu Hua still let him play. Experimentation is the fastest step to accumulate experience, as long as you are careful not to make mistakes.

And Xu Rui, who is meticulous by nature, is well qualified for this link.

After the key point of the experiment was reached, the whole person put down the notebook and pen that recorded the first experiment to make nitrocellulose, picked up the beaker with sulfuric acid in the right hand, and poured it into the large-dose beaker with nitric acid below, with a serious face and mixed acid.

According to the proportion requirements specified in the experimental records, Yu Hua quickly prepared the mixed acid that met the requirements.

The starting point of all nitrating compounds comes from sulfuric acid and nitric acid. Nitric acid is the main body of the nitrification reaction, and sulfuric acid is the catalyst for the entire reaction process, whether it is nitrocellulose or nitroglycerin.

"Ruizi, pay attention to the proportion and time of the mixed acid configuration here. Both must be well controlled, especially the proportion, which is the most important. The proportion of mixed acid used in the production of nitrocellulose is generally... In addition, attention must be paid to the method, and the whole process must be careful. "Yu Hua was like a lecturer in the classroom, while conducting experiments, he explained the key points of knowledge to Xu Rui.

These valuable chemical experiences are unknown to any high school student during the Republic of China, even the top high school of Peking No. [-] Middle School.

The lack of experimental equipment and funds made the high school students in the Republic of China basically have no experience in chemical experiments.

Like a thirsty sponge, Xu Rui paid attention, listened carefully, and recorded every knowledge Yu Hua imparted as much as possible.

"The mixed acid is ready, let's go to the next step."
