"Big nephew, you can't do this, you will disappoint your father and uncles, if you can't complete the task under Your Majesty, then what should you do?"

When Yang Heng led the children back from the mountains the next day, the first thing that greeted him was the third uncle's courageous complaint.

"That, third uncle, what's wrong, you sit down and talk slowly." Yang Heng smiled and let the third uncle sit down, this is the first time he has seen someone angry, you must know that Lu Dao, except for the few days when he just crossed over, his father was always angry with him, he has never experienced this kind of thing, at this time, looking at the third uncle like this, he felt very interesting, and even happy in his heart, finally, someone can make a different voice, otherwise, it has always been his voice in this family, that is not good, even if he is a traverser, he was not a successful person in his previous life, It's still possible to make mistakes.

In this way, the criticism and education of these indigenous people still need to be accepted, but this needs to be said correctly and in his heart.

"Don't look at me with such a smile, I'm telling the truth, it's not possible for you to lead the children to play all day long, I know that there are my children in it, but I will still be unhappy, you must know that you represent our five families, or our family."

That, you're wrong, it's not five, it's six, you know, I'm separated from my father, and it originally belonged to two families, although it is said that it is now combined, but we are still six families, right, however, Yang Heng did not show it on his face, but continued to listen to the third uncle.

"I also know that there is something important in your mountain. But you lead the children together. That's not a big deal. You say I'm right. "No, no, naturally this time is an important thing, but, this has to do with the baby, isn't it, taking the baby and not bringing other children, doesn't it seem bad?

Although Yang Heng was slandered. However, he did not refute the third uncle, "Uncle, you continue." "You see, on the day you left, there were a few workers in the factory who finished their work, and they were also idle, and my uncle didn't know what new work Lu Dao had assigned to them, and even the person in charge didn't know how Lu Dao had arranged it, because you had a new task. I don't know yet. ”

"Ah, uncle. There are finished, how many have been completed? "How much has been done, almost all of it is done today." "Well, I accept my uncle's criticism, I will go to the factory first, and listen to my uncle's teaching when I have time." As he spoke, Yang Heng got up and ran out.

"This kid is always in a hurry, listen to me in the future, I dare, now I'm sweating, and I'm even more nervous than seeing Your Majesty." The third uncle also stood up, but almost fell, what's wrong, some dehydration, sweating too much. It can be seen what kind of prestige Yang Heng has at home, although he usually does not show it, but if anyone has thoughts about him in his heart, it is a huge pressure.

You have to know that the development of these families, that is to say, the development of the new Yang family, but they are all supported by Yang Heng, this is like a snowball-like development, if it is only snowballed according to the speed of the linear speed, then the development is already considered to be a god speed, but under the leadership of Yang Heng, it is developed according to the speed, how fast you say the development, perhaps, the uncles do not understand the theory of this snowball, but they know that once Yang Heng is gone, this new family will be shattered, just like a snowball, it will eventually break, then everything will become zero, but if this snowball develops to the extreme, and then becomes permanent frozen ice, it won't break, right?

All in all, Yang Heng is now the pillar of the Yang family, the keel of a big ship, once something goes wrong with Yang Heng, this house will fall, this big ship will collapse, it is like this, this is the unanimous opinion of the uncles, this is the unanimous opinion of the uncles, this is the decision in the form of guessing who will persuade Yang Heng, naturally, the third uncle is the unlucky ghost.

"The third child, how's that, how is it. Ah, what's wrong with you, you were thrown into the well by your eldest nephew. "Hey, I said you, why don't you pour me some water to drink, I'm dehydrated, remember, put some salt in it, otherwise, I won't let you go."

…………

"Yes, yes, that's what it looks like, don't look at it as a small adjustment, let me tell you, it's a matter of efficiency. The efficiency of our original steam engine was only about 3 percent, and it was only 5 percent at its best, and the initial efficiency of this new steam engine was about 8 percent, and now after these improvements, I estimate that it can reach 15 percent, and my greatest wish is to be able to reach 20 percent, and I am very satisfied. ”

"Owner, is this as unbearable as you say, and what is efficiency?" It turns out that you didn't understand it, that is, you listened to a percentage, which is very easy to understand.

"The so-called efficiency, have you heard of the accidents in the coal mines of those wealthy families?" "I heard." "By the way, you think that they have such a big accident for something, which is the reason for the high efficiency, I estimate, their efficiency there has reached more than 50 percent, just like that little explosion, you have also seen this, right?" "Hmm." "Why do we use so much coal to burn, so that this steam engine can drive such a little thing to rotate, there is cold loss, there is heat loss, and there is friction loss, you just remember this temporarily, I will explain it to you slowly in the future."

If you want to say how Yang Heng calculated, this needs to start from Yang Heng's memory of his previous life, his memory of the steam engine in his previous life is that the efficiency of the steam engine is only about 42 percent, and through the comparison of various powers, as well as the bore and travel distance, he is guessing, thinking comprehensively, there is only this ratio, this is naturally not calculated by Yang Heng, and the calculation is quite troublesome.

If, after conducting multi-cylinder research, his goal is to achieve this result of about twenty-five percent, and to use it on trains, it will be enough.

Finally, the new generation of steam engines once again let out its roar. "Load." Yang Heng gave an order, and a lathe behind it turned very easily.

"Quick, let's try machining a large workpiece." This time, Yang Heng did not have any processing goals, just for test runs.

"A section of the rapid knife, normal, two sections of the knife is normal, three sections of the knife is normal, the fourth section of the knife is normal, some feel strained, five sections, some hold the car, the test is completed, the best working speed of the knife is three speeds, between the four speeds, which is much stronger than the half speed of the waterwheel, the speed of the primary steam engine." Here, to illustrate, Yang Heng is to set the lathe feed speed to set five speeds, naturally, the highest five speeds are to process some softer materials, and at first, when he used the wheel, he wanted to use a section of speed, but the result was not successful, and then changed to half a speed, which can be used, but it is this half speed that has made a great contribution to him.

Also, the improvement of the efficiency of the steam engine is not a simple matter of addition, it is basically the difference between heaven and earth, no, this new generation of steam engine has fully met the requirements of fixed power, at the current stage of Datang, in various places, in addition to being used on the train, no matter what to do, it has already met the needs, and even, next, Yang Heng is going to remove the steam engine from the lathe, and then the motor is on the horse, how much to look forward to the arrival of the electric era, with the golden finger, That's different, what, the steps are too big, so that you have a plane to drive, will you still ride a bicycle to run hundreds of miles, or, what, how to write history, that's a historian's business, I don't believe it, after a few hundred years, the historian will still dig the grave and whip the corpse, yes, then it will be cremated directly, after cremation, the ashes will be scattered in the sea, and the historian will whip the corpse of the sea.

However, as a motor, there is still a problem, that is, the problem of the iron core, you must know that in the previous life, the silicon steel sheet with a fairly high permeability was used, this is the matter of the steel research tutor, as long as the subject is handed over to them, this still needs Yang Heng to do it himself?
