There are still many problems with the steam locomotive, this car can only be used as a test car, and it cannot run on the railway at all, and these problems need to be improved slowly. Pen, fun, pavilion www. biquge。 The current steam engine technology cannot be put into industry, it can only be used for experiments, and the technology needs to be improved step by step.

Wang Xinyu is not a god, nor is he a mechanical major, but a chemical major, and he doesn't know very much about the key components of the steam engine, to be honest, and many things still need to be explored by those scientists themselves.

After seeing the steam locomotive test, Wang Xinyu went to Song Yingxing's house to visit.

The Soong Ying Xing Mansion on Dongfan Island is located on a high slope by the sea, which is the location of the original Utlicht Fort. It was a hill facing Anping Castle. The original Fort of Utlicht has now been turned into a villa area, where most of the scientific researchers live, and a railway more than ten miles long has been built from here to the gun factory, and there are rail carriages to transport them to and from work every day.

Wang Xinyu took a rail carriage and came to Song Yingxing's mansion.

"Lord Wang, let's go and inform the master!" Seeing Wang Xinyu coming, the guards at the door were about to go in to report.

Wang Xinyu hurriedly stopped the guards: "No need, otherwise I will trouble Mr. Song to come out to greet him in person, or this clan can go in with Song Gongzi!" ”

The two walked into the house, Wang Xinyu saw a smell of medicine wafting in the inner courtyard, and there was a maid boiling medicine in the kitchen, it seemed that Song Yingxing's body was really broken. In this era, there are very few people who live to be eighty years old, and it is normal for people to fall ill at this age. Song Yingxing is a literati, but he also often exercises and does farm work, so his physical fitness is relatively good, and it is very good to live so long in this era.

Just last year, when Wang Xinyu came to Dongfan, Song Yingxing was still busy on the front line of engineering construction, and he was still very proud to say that he could live for another five years. It's only been less than a year, and his body has collapsed, and it's really hard to say what happened to him as he gets older.

Song Yingxing, who was lying on the sickbed, heard someone walk in, raised his head to look, and saw that it was Wang Xinyu who came in! Although he is old, his mind is very clear, people who often use their brains are not easy to get old and confused, that is, Alzheimer's, Song Yingxing's mind is still very sober, and he recognized it at once, it was Wang Xinyu who came in. He struggled to get out of bed.

Seeing this, Wang Xinyu stepped forward with an arrow step and supported Song Yingxing: "Mr. Song, lie down quickly!" ”

Song Yingxing said with tears in his eyes: "Lord Wang, the old man is old, and it seems that he will die soon!" I only hate that the old man can no longer do things for the prince, and I can't see my Ming Dynasty pacify the Central Plains for a day, which is the unwilling place in the heart of the old man. ”

Wang Xinyu smelled a strong smell of medicine in Song Yingxing's bedroom, and then looked at Song Yingxing, and the crane-haired and childish face he saw last year were completely two people. But now, his face was yellow and thin, his eyes were deeply sunken, the skin on his face was wrinkled like dried orange peels, and his arms were stretched out, looking thin and thin.

"My father couldn't eat for five days in a row, so he could only drink some porridge." Song Shihui said.

Wang Xinyu knows that it is the failure of the elderly human organs, which will cause this symptom, according to the medical perspective of later generations, it is the gastrointestinal dysfunction and multiple organ failure, in this case, the person is already about to die, even the medicine of later generations cannot be cured, let alone this era.

Thinking of this, Wang Xinyu felt that his eyes were a little wet.

Song Yingxing said with a smile: "The prince doesn't have to be sad, the old man has lived to be eighty years old, and he has lived enough!" And the old man also saw that my Ming Dynasty had become stronger! The only regret is that I can't do things for the prince anymore! ”

"Mr. Song, don't say that, you will definitely get better! I will see the day when my Ming King recovers the Central Plains! The matter has come to this point, Wang Xinyu can only hold Song Yingxing's hand tightly and comfort him.

Song Yingxing said: "The old man knows his own illness, life is rare for seventy years, and the old man has lived for eighty!" ”

At that time, there was no air pollution, and there were few diseases such as hypertension and myocardial infarction, but not many people lived long because of malnutrition and poor medical technology. Song Yingxing is not only a scientist, but also knows some medicine, so it is normal for him to live a lot longer than others.

But even so, the average physical fitness of human beings in that era was not as good as that of later times.

"Mr. Song is recuperating well, don't think about anything during this time." Wang Xinyu said.

Song Yingxing said: "I heard that the steam engine is already running, but I haven't gone to see what is going on." ”

Wang Xinyu said: "I went to see this domain today, and I can run on the track, but it is still very unreliable, and it will break down after a while, and there are still many problems that need to be dealt with." In addition, the power is not large enough, and there is no way to make a larger boiler for the time being. ”

According to the principle of surface area and volume comparison, the larger the object, the smaller the surface area required per unit volume, which means that a larger high-pressure boiler requires a stronger material. In addition, the power of the steam engine should be improved, and the tightness, the bearing capacity of the cylinder, and the technology of materials science should be improved. However, there was a small steam engine first, and then it slowly developed to have a larger steam engine.

Human science and technology are not ascending to the sky in one step, but are steadily mastered and steadily developed.

At this moment, Song Yingxing's gray eyes suddenly shone brightly: "Lord Wang, the sulfur acid plant is about to be built!" I don't know when the prince will have time to go and see? After the sulfur acid factory was built, the old man asked a son who was not angry to go there to do things, although the dog was talentless, but he was still relatively diligent. ”

Wang Xinyu hurriedly said: "Thank you, Mr. Song!" If Song Gongzi can go to the sulfur [acid factory, he is just a talent! ”

Song Yingxing's father and son's knowledge of Chinese studies is good, in real history, because the Manchu Qing Dynasty entered the Central Plains, Song Yingxing was unwilling to do things for the Qing court, so his son's talent was also buried in the long river of history. Now that Wang Xinyu's sulfur acid plant and nitrate acid plant are about to be put into use, it is the most suitable person to let Song Yingxing's son become the factory director.

With those two factories, it will not be a problem to manufacture new explosives in large quantities in the future! There is also a projectile that can be improved, and nitrate fiber gunpowder can be used as a propellant, so that the musket and artillery are fired, and there is no longer a choking white smoke, but a faint blue smoke.

Not only that, but the improved propellant makes the guns more powerful.

With these two plants, primers for ammunition are no longer a problem, and mass production of firing needle weapons can begin. (To be continued.) )
