Chapter 34 second quarter

After Xiong Dazhen returned to Jizhong, he created a spring belonging to the Technology Research Institute.For a whole summer, the technical research institute he led had frequent success reports. One day after Xiong Dazhen went to Tianjin, the headquarters of the Jizhong District held a meeting. They had just fought a small battle, invested a lot of troops, wasted a lot of ammunition, and had limited annihilation of the enemy.At the meeting, some people complained that the mortar shells made by the repairing equipment of the supply department were not effective, and they were blinded at the critical moment. Seeing that the enemy's car was about to blow up, no one could imagine that "hail" fell one after another on the enemy's head. It just didn't explode, which frightened Little Japan half to death, but he couldn't die, watching them drive the car back again.

This is the work of naming and criticizing the Ministry of Supply. Li Meng is currently serving as the secretary of the supply department. He is a person who cannot be easily swayed. Although Minister Xiong is not here, it is related to the collective honor. How can he sit idly by? So he also came up with a joke to fight back. He said: Sometimes giving you good guns and guns may not necessarily make you fight a good war.We all know that the guard company of the second regiment is well equipped, and there is a big 38 cover that drains a lot of water.Once when I was on an errand, I passed by their station, just in time for this platoon to carry out its mission. There was intelligence that a motorboat of the Japanese devils appeared in this area, and it seemed to be performing a reconnaissance mission.The intelligence personnel were very clear about the devil's route, time, and location.I think this time I can catch up with the western scene. I haven't seen real swords and guns fighting devils, so I went with the team.As a result, the motorboat really came, and the battle really started, but after fighting for thirty or forty minutes, they just couldn't fight.What do you think is the reason?Most of the platoon was recruits, and they had never even seen a target.As soon as the gun was fired, I panicked, and most of the 10 bullets fired by each person were released into the sky.A recruit next to me was trembling like a pendulum. He forgot that three points made a line. How could he be accurate?There were only 5 Japanese devils on the motorboat, and their guns were so accurate that they bit your head one by one, so that you couldn't lift your head up.Later, the devil's motorboat twisted into the reeds and was surrounded by us, and finally solved it with a big knife.You say that the war is not fought well, is it because our supply department is fair?

Commander Lu laughed out loud after hearing this, and said, "Intellectual Li Da, are you telling the truth or a lie?" Li Meng said: Whoever lied to you was fished out of the water.As he spoke, he made a crawling gesture with one hand. Everyone laughed loudly. Someone laughed and scolded: Li Meng, you are not big or young, how dare you talk to the commander like this! Li Meng hurriedly saluted Lu Zhengcao, and said: I'm sorry, I have apologized to you old man. Lu Zhengcao waved his hand: Great intellectual, what you reported is really a problem.How do you solve the problem of inaccurate shooting?

I suggest organizing target-shooting training for recruits, and then engage in live ammunition shooting after training! Before Li Meng finished speaking, everyone burst into laughter again.This time I laughed louder than last time. What are you kidding?Did you, Li Meng, eat too much rice? !Do you know how precious a bullet is?Our arsenal can't make it, and if you make one, you will lose one. How can you let you play around casually, nonsense!Everyone rushed to attack Li Meng. Li Meng refused to accept it, stood up, put his hands on his hips and said: Don't tell me, I just learned dialectical materialism, which is called dialectics. Instead of wasting bullets in war, missing the opportunity and losing, it is better to spend a small amount of bullets in normal training In exchange for the experience of shooting guns, you can accurately and powerfully kill the enemy on the battlefield!

Li Meng shouted at the top of his voice, which made everyone think.There was a moment of silence in the venue. The chief of staff of a division slapped his thigh and said: Li Meng's idea is good, it's the reason.However, we have a lot of bullets. If we use them for training, what should we do in wartime?You can't do it with a devil with an empty gun, right? Li Meng waved his hand to signal everyone to be quiet.He pretended to be mysterious and said: Our Minister Xiong will come back from Tianjin in two days, and he will bring you many surprises.I can give you a letter first. It will not be long before our technical research institute will be able to develop bullets and shells "made in Jizhong". We will also produce high explosives that are several times more powerful than old-fashioned explosives. , not only can blow up the enemy's military vehicles, but also can blow up railways and bridges, and can also blow up Gou Ri's trains and armored vehicles...

Li Meng's words lifted everyone's spirits, and everyone's emotions were instantly ignited. So what are you talking about, as long as we let our guns eat and drink well, will we still worry about not being able to win the battle? Your supply department is not bragging, is it?We can wait for your "Made in Jizhong"! The meeting was over, and Li Meng's mouth was as thin as a piece of paper.He returned to the supply department with the hope and mission of the whole region, and reported to Xiong Dazhen who had just returned from the tasks assigned by the head of the upper military region to the supply department.

As a result, the earliest scientific and technological training activity in the history of our army kicked off in the Jizhong Military Region... The task of making explosives was mainly completed by Wang Dexi, Yan Yuchang, Zhang Fang, Ge Tingsui, Zhang Kuiyuan and others.Wang Dexi is the person in charge of the "project team". Wang Dexi changed his name to Wang Huaichang after arriving in Jizhong, Yan Yuchang changed his name to Menbenzhong, and Ge Tingsui changed his name to He Jin.Wang Dexi is not tall, elegant, elegant and suave.He is versatile, although his major is chemistry, he is extremely talented in music.He can play the piano well, and his violin has reached the level of professional performance.Usually with a reed leaf in his mouth, he can whimper and blow the sad and moving "Jiang He Shui" all the time.When he is free, he loves to look at the reeds in the sunset, and the endless reeds fascinate him.He said that he became attached to this place, firstly, because of the teacher's order, and secondly, because of this reed.The reeds in Baiyangdian Lake are famous all over the world, and the content of his graduate thesis is "making paper from reeds".If the war is over, he will definitely come here again and suggest that the country build a paper mill here, using reeds as raw materials, which will definitely produce the highest quality paper in the world.He joked that if he really opened the factory, he would definitely invite everyone to visit again as the protagonist, eat fish from Baiyangdian, drink shochu from Renqiu, and be a drunkard of Gaoyang...

Of course, Wang Dexi's most admirable thing is his professional ability.He produced a potassium chlorate mixed explosive. This high explosive "made in Jizhong" almost accompanied the entire process of the Anti-Japanese War in Jizhong.When making dynamite, heat a certain amount of vegetable oil in a water-jacketed pan, add tnt explosive, then melt it, and finally add potassium chlorate powder, mix it into a uniform powder, and a new high explosive is made.Put the prepared explosives in a tin barrel and detonate it with a detonator, and it will explode with great power.In the past, the explosion speed of old-fashioned explosives was only 300 meters per second, but the explosion speed of Wang Dexi's "Made in Jizhong" was as high as more than 2,000 meters per second. This kind of explosive force is enough to deal with the Japanese trains speeding on the Beijing-Hanzhou Railway. .

The "Made in Jizhong" explosive has been made, and its power still needs to be tested.Wang Dexi proposed to blow up the Japanese locomotive.This proposal was approved by Xiong Dazhen, because the railway lines stretching around the Jizhong Military Region are like deadly ropes, blowing up the enemy's locomotives and railways, disrupting and paralyzing the enemy's traffic, which undoubtedly has great strategic significance. Test work started. Xiong Dazhen reported this to the head of the military region, and asked the headquarters to dispatch engineers from various divisions for training.The purpose of the training is twofold, one is to learn how to make "Jizhong-made" explosives with water jacket pots, and the other is to learn how to use "electric fire mines".Once the entire military region learns to use the new explosive technology, it will deal a heavy blow to the Japanese troops in the Beijing-Tianjin area.

Yan Yuchang played an important role in the development of the "electric fire mine".In the past, the common method of mine blasting was to ignite it with fire. The fuse was directly stuck on the nozzle of the detonator, and the fire reached the thunder.But this method has many disadvantages. To deal with the fast-moving train, there are too many variables and the means are too primitive, which is neither accurate nor easy to be discovered.Later, the flashlight bulb was broken, its filament frame was installed in the detonator, the detonator was changed into an electric detonator, and the battery was used as the power supply, and the positive and negative poles collided to cause a fire and explosion.But this method is also prone to mistakes and difficult to operate.Yan Yuchang brought some ultra-thin white metal wires from Tsinghua University, welded them to the tops of two copper wires fixed with adhesive tape, and installed them in the detonator, thus changing the ordinary detonator into an electric detonator .Before detonation, it is also possible to test whether the circuit is unblocked with a weak current to ensure the success rate of the explosion.

Yan Yuchang was tall, thin and weak.He belongs to the type of natural craftsman, what objects are manipulated by him, they will be subdued immediately.In the Technology Research Institute, if Wang Dexi and others are creators and designers, then Yan Yuchang is the doer and practitioner.His temperament is also different from Wang Dexi, Wang Dexi loves to talk and make trouble, but he is taciturn; Wang Dexi is like a lark in the forest, but he is as calm as dew in the forest.He also had an air of melancholy.You feel a heaviness when you are close to him. In the atmosphere of both lyricism and sadness, in the depths of the reeds in Baiyangdian, a plan is quietly approaching completion. In order to make the explosion more effective, it is necessary to experiment with the density of the charge. The textbook "Advanced Explosives" shows that if the density of explosives is too large or too small, it will have an adverse effect on the explosion. Only when the density is appropriate can the best explosion effect occur.Zhang Fang is a physics student. Seeing that Wang Dexi was always pressing and squeezing when charging the powder, he was afraid that the amount of powder would be too small to affect the explosion effect, so he questioned his approach.Wang Dexi accepted Zhang Fang's suggestion and found two iron barrels of the same size but with different dosages to do the experiment.They were very good friends, so they joked a lot.Before the experiment, Wang said to Zhang: Make a bet, I still think that the more medicine, the more powerful it is.Let's talk about the ugliness earlier, whoever loses will run around the neighboring village naked, do you dare to make this bet with me?Wang Dexi asked Yan Yuchang to be a witness.Zhang Fang's female classmate Liu Yun works in a military hospital in a neighboring village. The two are developing a relationship.But he didn't show any weakness at this time: bet, bet, maybe who is running around naked!Seeing this, Xiong Dazhen laughed up and down: This idea is very good, no matter who is naked, there are amazing performances, Allah supports you! "Boom" explosion overshadowed the laughter.Everyone ran to the explosion point. Wang Dexi lost.The hole produced by the blasting of the iron barrel with more charge is much smaller than that of the iron barrel with less charge, and there is still a lot of residual medicine in it. Wang Dexi hugged Zhang Fang happily, and said repeatedly in English: You are right, you are right! The two were busy calculating the data, and had long forgotten about the bet. During lunch, Yan Yuchang suddenly said to Wang Dexi: Why do you want me to be a witness?If you lose, you won't cash in. You eat more than me, sorry!Words spoken by honest people have amazing effects.Everyone burst into laughter with a bang. After all the experiments had reached the desired targets, Wang Dexi led the engineers and soldiers to set off in the dark of a month. During the day, they have already stepped on the spot.Taking advantage of the dark night, they buried 12 large iron barrels containing explosives under the railroad tracks, plugged in the electric detonators, and pulled the wires several hundred meters away. Waiting quietly for the train of the Japanese devils to appear. At midnight, a little light flickered in the distance, flying like fireflies. The sentinel on guard duty ran over and reported breathlessly: Here we come, here we come! The train whizzed by, and the bright lampposts cut through the night.At the moment before the explosion, Wang Dexi actually had the idea of ​​composing a poem. He saw that the locomotive was approaching the explosion point, so he touched the positive and negative poles of the wires together. With a sound of "stab", a bright little spark jumped out of his palm, and then he saw a ball of flames soaring into the sky a few hundred meters away. Amid the huge explosion, the enemy's locomotive flew into the air... … The train bombing incident aroused great repercussions in the country.Although the Japanese invaders suffered various attacks along the railway line, they had never encountered such a violent explosion: after the locomotive was blown over, the rear car body derailed, and the materials loaded on the car exploded and caught fire during the collision, causing extremely heavy losses.The Japanese Army Ministry said in a briefing: "It is believed that this is an explosion that has never been seen before." This may be the first successful case of blowing up a train since the War of Resistance in North China. This is also the first loud noise created by Tsinghua people in the War of Resistance. More importantly, the Technology Research Institute led by Xiong Dazhen has created a new combat style, which is to explode the roads, railways, bridges, stations, ports, etc. in the enemy-occupied area, which can greatly weaken the enemy's ability. The mobility and combat capability of the army made it fearful and disturbed, and the morale of the army was shaken.This method of warfare was later generally accepted by the anti-Japanese troops in Shanxi, Chahar and Hebei. Especially after the "Hundred Regiments War", the Japanese invaders wrote this in their "headquarters army department" war history when talking about "railway damage": The damage to the railway was extremely serious, and the scale was beyond description. The enemy used methods such as explosion, burning, and sabotage in an attempt to completely destroy important technical facilities such as bridges, tracks, communication networks, and railway stations.When carrying out sabotage, concealment and camouflage are extremely ingenious. ("Long Compilation of Materials on Japanese Militarism's Invasion of China" (Part 1), edited by the Japanese Defense Agency, translated by the Tianjin Municipal People's Political Consultative Conference Editorial Committee, Sichuan People's Publishing House, 1987 edition, pp. 582-583) For Jizhong District, using powerful explosives to continuously destroy the enemy's traffic actually provides a guarantee for the survival of the base area, which is of strategic significance.The major cities in the east, west, north, and south of Jizhong District fell one after another. If the railways and roads were unimpeded, no matter whether it was from Pingjin or Shijiazhuang, the troops could arrive in half a day.It was the advanced explosives produced by the scientific and technological talents dug by Xiong Dazhen using professional knowledge to continuously attack the enemy, which effectively interfered and contained the intention and determination of the Japanese army to attack the Jizhong base area.Regarding this point, the military leaders in Jizhong District are well aware of it. Therefore, Commander Lu Zhengcao appreciates Xiong Dazhen's work very much, and the name of the Supply Department is becoming more and more famous in Jizhong District. Due to continuous explosions, the demand for explosives is increasing. Considering the limited source of potassium chlorate, Wang Dexi wants to manufacture ammonium nitrate mixed explosives. Before the production, Wang Dexi and Yan Yuchang went to Beiping and Tianjin respectively.Wang Dexi found Mr. Ye in Tianjin, and sent him a letter from Xiong Dazhen and a list of urgently needed supplies.Ye Qisun quickly prepared the items, so that he returned with a full load.When Yan Yuchang came back from Beiping, he almost moved the laboratory of the Department of Physics of Tsinghua University here.He disguised himself as a refugee fleeing from famine, and carried a bedroll. The rucksack was filled with detonators, chemicals, glassware, and the formula for making ammonium nitrate that was tested by students of the Chemistry Department of Tsinghua University was sewn into the quilt.Thanks to everyone's brainstorming, ammonium nitrate mixed explosives were quickly manufactured. It is unique to conduct experiments in the wild environment.They set up a large pot deep in the reeds, and then put the fire nitrate and fertilizer powder into the iron pot to heat and melt them. Taking advantage of the difference in solubility of the two, they kept adding to make them react, and at the same time, they used an iron fence to fish out the nitrate. , Put the solution in the pot into another container to let it cool, and the crystals of ammonium nitrate will come out.Ammonium nitrate is used instead of potassium chlorate, and vegetable oil and tnt are added, so the so-called "ammonium nitrate mixed explosive" is made. After detonation, its detonation speed is the same as that of potassium chlorate mixed explosive. Due to the need for a large amount of ammonium nitrate, they had to stay by the iron pot all day, and a scientific experiment turned into hard physical labor.At this time, the protagonist of the work was still Yan Yuchang, while Wang Dexi, Zhang Fang and the others assumed the task of observers.But Wang Dexi couldn't calm down for a moment, he would force everyone to write poems and lyrics on the iron pot, so that the sun, moon, stars, dawn, and sunset all fell into the pot, and in the stirring with a little poetry, Being warmly and drippingly scooped out of the pot by these temporary poets, they solidify together with the solution into a permanent memory.Among these people, Wang Dexi's poetic style is graceful, Zhang Fang's style is bold and unconstrained, while Yan Yuchang is a folk poet. Under Wang Dexi's coercion, he will also be forced to make a "final roar"——
