Chen Jingyun wanted to go to see it, Tang Huikang immediately took Chen Jingyun there, and on the way, Tang Huikang also explained some artillery matters to Chen Jingyun, such as what problems and troubles were solved, and the technician made great efforts.

Soon, Chen Jingyun saw the two cannons in front of him. This gun is a 75 mm caliber, and the barrel is not about thirteen or fourteen times longer, so you can see at a glance that it is a typical 75 mm mountain gun. Looking at this appearance style, Chen Jingyun can probably guess that this should be an imitation of the German 75-mm mountain gun.

At this time, Tang Huikang also explained: "When we developed artillery, we referred to the German-made 75 mm artillery equipped by our army, and the long-barreled field artillery (about 30 times the caliber) could not be solved for the time being because of the barrel and steel problems, but the short-barreled mountain artillery (14 times the caliber, 17 times the caliber) We solved most of the technical problems through various methods. According to some technical parameters of German-made and Yue-made artillery, plus some of our own designs, this artillery was designed.

The caliber is 75 millimeters, the barrel is 14 times the caliber, the weight is 550 kilograms, the muzzle velocity of the shells is 280 meters per second, and the standard range is 4,500 meters. It is much the same as the two 75-mm mountain guns that our army has in its current armament. ”

Tang Huikang explained simply, Chen Jingyun stepped forward after listening to it, and also looked at the two mountain cannons carefully, but after reading it once, he knew that he couldn't see anything based on the appearance alone, and immediately said: "Let them shoot a few shots!" ”

Chen Jingyun asked for a test launch, Tang Huikang was naturally overjoyed, and then after letting the technicians below quickly get ready, he also retreated to the high platform behind with Chen Jingyun. The test firing of this artillery was very dangerous, referring to the previous test firing failures, but many technicians were killed and wounded. Now, when artillery and other dangerous weapons are test-fired, Tang Huikang has strictly ordered that technicians be forbidden to test-fire in person, but that the dangerous work of test-firing is handed over to artillery and other soldiers of the Nationalist Army. In Tang Huikang's heart, the important surname of a technician is much more important than that of an ordinary soldier of the National Army.

The test firing below was quickly prepared, and then as Chen Jingyun nodded, the two artillery pieces below began to fire live ammunition for shelling, while Chen Jingyun was holding a telescope to observe the explosion and impact point in the distance. With the dull sound of several cannons, a small hill in the distance soon exploded, and then rolled up smoke and dust, the rumbling cannon did not stop, and the smoke and fire in the distance also continued, and the two cannons each fired more than ten shots in a row before they stopped.

When Chen Jingyun saw this result, his face was full of joy: "Okay, now our artillery can finally be made by itself!" ”

Tang Huikang saw that Chen Jingyun's face was full of joy, and the worry in his heart was put down, he was worried about an accident during the test launch just now, and it would be completely finished.

Chen Jingyun stood up in a good mood: "This mountain cannon is there, after you improve it, I will ask the equipment department to place an order for you here, and in addition, you must get the field cannon with a long body as soon as possible!" ”

Tang Huikang naturally nodded yes, but this mountain artillery and field artillery are different, the mountain artillery mentioned in this year generally refers to the short-barreled artillery of more than ten times the caliber, light weight, can be used for artillery support in mountain operations, that is, howitzers in the traditional sense, and field artillery, generally said about thirty times the caliber or more of artillery, used for long-range shelling, that is, the so-called cannon. Of course, howitzers and cannons have different meanings in each period, and artillery of forty or fifty times the caliber in later modern times can only be called howitzers.

The length of the barrel is not the same, which means that the technology required to manufacture the barrel is not the same, and then in the final analysis it is the steel problem, and the current Southeast Iron and Steel is not able to produce special steel that can meet the needs of the long-barreled artillery for the time being, so the current technical conditions of the Fuzhou Arsenal do not have this ability for the time being.

However, this situation will be completely changed after the steel plant built with the help of the United States is put into operation, and Chen Jingyun spent a lot of money to introduce the manufacturing technology of 75 mm cannons and 105 cannons. This is said to be artillery manufacturing technology, but in fact, to put it bluntly, it is the manufacturing technology of steel for cannon barrels, that is, special steel.

As long as the steel is qualified, then it will not be a problem to produce artillery in large quantities according to the current technical capabilities of the Fuzhou Arsenal.

Today in the southeast iron and steel plant walked around, and then to the Fuzhou arsenal walked around, and when I returned to the governor's mansion it was already evening, originally thought to have a good rest, but when I went back to see, I found that there were people from Liuhe Lane, not only from Liuhe Lane, but also from Uncle Chen Jingyun's house.

After asking, I learned that it turned out that Uncle Chen Jingyun's wife died last night, and I heard that it was just an occasional cold, but both Chinese medicine and Western medicine have seen it but it is not good.

So many people came to the Governor's Mansion to report the funeral, Chen Jingyun also felt something in his heart after hearing it, he had seen that lady once or twice, but he didn't expect that if he didn't pay attention, the person would be gone.

"The doctor didn't see what the disease was?" Chen Jingyun asked.

There was no need for Lin Yun to answer, an old mother from Uncle Chen Jingyun's mansion took the initiative to respectfully reply: "Back to the third master, Dr. Smit, who came to see my wife, told me that he had a cold, and then it turned into pneumonia again!" , say what tuberculosis! ”

Chen Jingyun frowned when he heard this, and then said, "Tuberculosis? ”

The old mother nodded hurriedly: "Yes, yes, that's what he said, saying that there is no rule of law for a terminal illness!" ”

Luo Li on the side also said: "Isn't this what tuberculosis is talking about!" ”

Chen Jingyun also knows that tuberculosis in this era is cancer, which cannot be cured, well, I heard that Cai Ye also has this disease, and he will have to go far away when he meets in the future, so as not to be infected. To treat tuberculosis is actually very simple, after the invention of streptomycin in penicillin, there is basically no big problem, with this antibiotic after the complete treatment of tuberculosis will not be a problem, the key is that the person who invented penicillin does not know where in the world to stay, and Chen Jingyun himself only knows the name penicillin, but if he wants to get it out Chen Jingyun will be blind.

In fact, since Chen Jingyun returned to Xinhai, he has always had the habit of taking notes, mainly remembering some things in his previous life, most of which are nouns, such as penicillin and sulfonamide in medicine. I know more about sulfonamides during World War II, and I don't know how many soldiers' lives were saved. But he is not an expert in doctors, it is good to be able to know a few terms for these medical things, if he really wants to remember the manufacturing methods of these drugs or some detailed things, then he Chen Jingyun is not a human, but a monster. Penicillin he only knew that this thing was extracted from something moldy, and then sulfonamide knew more, mainly because he had seen a related story before, saying that this sulfonamide was extracted from a red dye, and he had to ask others what the specific composition of this sulfonamide was and what dye it was extracted from. Well, it's okay if it's Baidu, but unfortunately Chen Jingyun doesn't have a computer in his hand now, and he doesn't have a network cable to contact future generations......

Although he used to have the habit of memorizing these, Chen Jingyun has always paid little attention to these things, he paid attention to the military, especially the development of the army, the production of military industry, etc., and did not pay much attention to some other minor things.

Now that he heard this, Chen Jingyun's mind was also activated. However, the development of drugs is not easy to do in person, this has to get an institution in their own industry to do, if the time comes, if the streptomycin can be developed, it can be regarded as a contribution to the world, and more importantly, sulfonamides, the strategic value of this thing is not much worse than the aircraft, tanks, artillery, this is more expensive than gold, after all, in wartime, if the military commander finds that there is a drug that can help him save the lives of the vast majority of wounded soldiers, Then he would not hesitate to spend a lot of money to buy it. Of course, the manufacturing technology also has to be protected, and as for what to apply for a patent or something, well, let's talk about it in a few decades.

Since Chen Jingyun thought of this, then he didn't want to delay, and directly sorted out some information about medicine, such as penicillin, sulfonamides and other information, although these things are just some very vague statements or nouns, but after all, it can give R&D personnel a direction, such as sulfonamides, Chen Jingyun already knows that it is extracted from a certain red dye, so what the developers have to do now is to find out sulfonamides from many red dyes. As long as there are sufficient manpower, material resources and funds, it is not difficult to find out. The process is also simple, that is, to inject all the red dye that can be found into the mouse infected with germs, and the red dye that the mouse dies in the end is definitely not, and when the red dye that not only survives the mouse is found, but then the germs in the body are destroyed, then that thing is sulfonamide, or contains sulfonamide, anyway, it is found out.

After sorting out these materials, Chen Jingyun directly asked his subordinate companies to find a group of chemists, and then recruited several experts in microbiology to directly set up a drug development laboratory. Then he gave these people all the information about the drugs in his hand, and he didn't bother to explain to these people why he wanted them to look for sulfonamides, penicillin, and explain to them why he knew these things, he just said simply: "Find them out!" ”
