Special Forces of Crossing: Cloud's Anti-Japanese

Chapter 93 Seeing Leighton Stuart Again
The expected rivalry scene did not appear, and the boys watching on the playground couldn't help but feel a little bit uninterested.While the girls watched Ouyang Yun walking towards the office building, they felt that his not tall figure suddenly became clear - no one thought he was a coward, on the contrary, it added to him the charm of a mature man.Many people couldn't help biting their lips, suddenly having a summer secret.

When Ouyang Yun scanned the crowd just now, he didn't find any students from the Special Service Brigade. He was very relieved. At this moment, they should still be in the laboratory, right?I am ashamed to say that, after all, I only know some theoretical knowledge, and his hands-on ability is not as good as that of those cadets. Things like cultivating the original strain of penicillin can only be left to them. This is the tragedy of plagiarism Well, it's just a pseudo-expert, who looks good but doesn't work!
The main research projects of the Secret Service Brigade are transistors and penicillin.

Historically, the transistor appeared on December 1947, 12. It was first invented by the Shockley group of the famous Bell Laboratories in the United States, and then quickly replaced the position of the electron tube in the electronics industry, thus creating the modern electronics industry. milestone.Transistors are solid electronic components made of semiconductors, the most commonly used materials being germanium and silicon.Since both germanium and silicon exist in natural substances in a chemical state, there is no high-purity germanium and silicon. Therefore, the first step in the research of a group of students is to find a way to extract materials from substances such as soot and silicates. Purification of germanium and silicon.

Penicillin is also the production of penicillin. With the current conditions that Ouyang Yun can use, he can only produce natural penicillin.However, in order to achieve mass production of penicillin, there are two steps: first, strain fermentation: inoculate Penicillium chrysogenum on solid medium, and cultivate it at 25°C for 7 to 10 days to obtain Penicillium spore culture thing.Then use sterile water to make a suspension of spores and inoculate them into the sterilized medium in the seed tank, introduce sterile air, stir, and cultivate at 27°C for 24 to 28 hours, and then inoculate the seed culture solution into the fermentation medium. Into the sterilized medium containing phenylacetic acid precursor in the tank, inject sterile air, stir, and cultivate at 27°C for 7 days, and add phenylacetic acid precursor and appropriate amount of medium during the fermentation process.Then extract and refine: cool the penicillin fermentation broth and filter.Under the condition of pH 2-2.5, the filtrate is subjected to multi-stage countercurrent extraction with butyl acetate in the extractor to obtain the butyl ester extract, which is then transferred to a buffer solution with a pH of 7.0-7.2, and then transferred to butyl ester. Decolorize the butyl ester extract with activated carbon, add a salt-forming agent, and undergo azeotropic distillation to obtain penicillin G potassium salt.

Because Ouyang Yun’s so-called penicillin mass production method is plagiarized, it is a relatively modern production method, and in China today, due to the weak chemical base, such as butyl acetate and phenylacetic acid must be imported, so they have to find a way to find other Alternative culture medium and extract - this is one of the reasons why Ouyang Yun wanted to start a chemical company.

Speaking of military industry, Ouyang Yun originally planned to plagiarize some designs and try not to be too advanced, preferably the ones that are super affordable and easy to manufacture - China's current industrial strength is like this, although he wears the hat of an American overseas Chinese, but Who knows what the surrounding countries will think if something like Su-27 is suddenly produced.The so-called big tree attracts the wind, and if it causes eyeballs, it may not be a good thing.In terms of light weapons, he originally wanted to adjust the AK-47 and get some rifle grenades. But after reading more computer data, he found that there was a firearm that was more powerful than the AK-47 at about the same time, that is, the Federal Republic of Germany launched it in 1957. The G3 automatic rifle.Compared with the AK-47, the G3 not only has a range of about 100 meters, but also because stamping parts are generally used and there are fewer machined parts, so the requirements for the production process are not high.More importantly, since the barrel of the G3 is longer and the caliber is 7.62MM, with a slight improvement based on this, a variety of gun types including submachine guns and sniper rifles can be derived.

In terms of machine guns, the German MG42 general-purpose machine gun is naturally the first choice. It only needs to change the feeding method, so it can not only provide the main fire cover for the squad as a light machine gun, but also provide important support for large troops such as battalions and companies as a heavy machine gun. fire support.What's more valuable is that it can also hit armored vehicles and tanks and become a vehicle-mounted machine gun. If two guns are mounted together, it can also become an anti-aircraft machine gun.

Since the current domestic army generally lacks anti-aircraft weapons, once this kind of machine gun takes shape, based on the arrogant and domineering habits developed by the Japanese aviation troops on the Chinese battlefield, it is estimated that once the Pingjin War starts, the MG42 will definitely become a nightmare for little devil pilots.

The only problem is that since G3 uses 7.62MM caliber bullets and MG42 uses 7.92 caliber bullets, solving the problem of the versatility of bullets has become a problem that must be considered by the three groups of students.Because Ouyang Yun provided the drawings, the three groups of students quickly made models with wood, and then with the help of ideas provided by Ouyang Yun, they designed light, heavy, and double-linked models based on a single MG42.The MG42 drawings that Ouyang Yun handed over to them were single pieces, and the reason for doing so was to cultivate their hands-on and brain abilities. The MG42 changed from a light machine gun to a heavy machine gun, and only the ammunition supply method was changed, and the anti-aircraft machine gun only needed to be double-linked and equipped with anti-air sights.However, since the anti-aircraft sight involves the problem of curved shooting, the corresponding data must be obtained through actual experiments, so the students could not come up with a specific plan in a short period of time.

The Secret Service Brigade is Ouyang Yun's baby bump, and its importance in his heart is no less than that of the computer that traveled along with it.So his security work is what he has always emphasized. He came here today to check the security situation, and to take the three groups of students to Renqiu.

Speaking of Leighton Stuart, the old American man is really good. I don’t know if it’s because he’s been in China for a long time. He doesn’t have the inherent rigidity of Westerners. A training place has been arranged.These places, including the laboratory, are all under the control of Fox Tong and Renqiu Special Police Squadron, and outsiders are not allowed to enter.Ouyang Yun had just appeared 20 meters outside the gate of the laboratory building, when a fox-eyed apprentice stood up from behind a tree, and instinctively said: "Please stop..." Before he finished speaking, he saw clearly that it was a passenger seat, and hurriedly saluted Said: "Report to the brigade, the fox pupil soldier Hou Jiaqiang is on duty! Are you going to the laboratory building?"

"Yes!" Ouyang Yun responded with a military salute and took out his pass.

Hou Jiaqiang took it and looked at it carefully, then put him in.

Ouyang Yun admired Hou Jiaqiang's serious and responsible attitude, and felt a little complacent, thinking that he looked like a regular army.Then he passed two guard posts before entering the laboratory.

The Yanda laboratory is a three-room, two-story, two-floor building. Originally, there were only two laboratories. One of the other rooms was used as a warehouse, and the other three rooms were vacant.Under the rearrangement of the Secret Service Brigade, one became a guard room, the laboratory became three, and one was a conference room.

Ouyang Yun first walked into the mechanical laboratory of the third group. Several students were discussing the issue of bullet diameter around the MG42 and G3 models. It would be better to change the bullet diameter to 3, and said with a smile: "Yes, as a machine gun, especially for anti-aircraft, the impact effect will be greatly reduced if the bullet diameter is too small. But have you considered this, the aircraft is made of steel or alloy, Can ordinary bullets penetrate?"

The apprentices only noticed him at this time, and many of them exclaimed in surprise: "Travel seat?" Then they all saluted.

Ouyang Yun returned the military salute, then picked up the model of MG42 with a smile, played with it for a while and said, "Not bad, who made it, the carpenter's craftsmanship is good."

Everyone looked at Gao Tian, ​​who rubbed his head and said with a silly smile, "My dad used to be a carpenter, so he learned a little from behind."

"Take the model and come back to Renqiu with me, our military factory is about to start up."

"That's great!"……

Ouyang Yun greeted them for a while, asked them to go back to the dormitory to pack their luggage, waited for him to tell them to go back to Renqiu together, then went to the laboratories of Group [-] and Group [-] on the second floor, visited the students of the other two groups, and Take a look at their experimental progress.Since they are in an unknown field, there is no precedent for reference, so most people are looking through the data, and the second group of corn used as a culture medium is still intact.

He knew there was no need to rush this matter, and he didn't have any good ideas for reference. After a few words of encouragement, he went downstairs to the principal's office to ask Leighton Stuart.

The American old man really helped him a lot. He came to him to thank him in person for the secret service brigade, and to ask him to help with the visa application.

Originally, the Americans did not set up a consulate in Beiping, and Jiang Shuren took a special trip to Nanjing with the letter of proof issued by Leighton Stuart for the visa.However, due to a change in the delegation, many of the businessmen withdrew, and the visa trip was wasted.Now, due to Song Zheyuan's instruction, the gang forces in Pingjin and Tianjin have begun to adopt some "road" methods against the Japanese; in addition, through the efforts of Jiang Shuren, an iron ore screening plant has been opened in the Yidong area, and it has been built in the southeast of Renqiu. A steel mill.Coupled with the role models of Gu Xudong and Shang Lang, the investigation team has added fresh blood, and finally the trip can take place.The good news is that just a few days ago, the Americans actually set up a consulate in Beiping, which made visas much more convenient.

This move by the Americans is somewhat strange, and even aroused the reverie of many politicians.You know, the 29th Army is now clearly a local government, and Beiping is equivalent to the "capital" of this small kingdom. What is the intention of the Americans to open a consulate here?If someone is lucky enough to know the two American spies, George and Robson, it may not be difficult to find the answer; of course, it may also have something to do with Gu Lianyun.

Ouyang Yun didn't think about it so much. This is a good thing. With Leighton Stuart's relationship, it is much more convenient to apply for a visa.
