Americans are a country that advocates individual freedom. They think that rich people are rich because of their ability. No one blames them for not helping the poor. They think this is moral kidnapping, but this does not mean that Americans
Disrespect for those who are good at helping others,
A caring person will be respected by others in any country. Coupled with Liu Lang's eloquence and eloquence, he cited Fleming's example, which suddenly raised his moral character to the level of a world celebrity.
Even Hanks was infected by his charisma.
Although Hanks has never heard of this legend...
Well, Liu Lang read this story from a domestic book. He thought Fleming was very noble, but is history really like this? Liu Lang didn't know that this story was just like Newton being hit by an apple.
The brain then discovered the "chicken soup" story of gravity.
But this is not the point. The point is that Liu Lang refused the patent transfer fee of US$650,000 and gave the other party the right to use this ladder for free.
"Jimmy, on behalf of Director Howard of the California Emergency Management Agency, I would like to express my highest respect to you!"
Banks and Makeda stood up and saluted Liu Lang solemnly.
"You're welcome, let's go through the relevant procedures now!"
"Yes, yes, hurry up and complete the procedures!"
Banks urged Makeda, saying that it would be useless to say anything until the relevant agreement was formally signed.
Makeda was a legal consultant, and the purpose of his coming was to be prepared for Liu Lang to raise the price, but the result was exactly the opposite. Liu Lang didn't want a penny and gave up his patent to the Emergency Management Bureau for free.
This kind of agreement is very simple. Makeda drew up an agreement, and Liu Lang signed the agreement. He also wanted to sign it, but was stopped by the other party. Americans don't pay attention to this...
"Chief Banks, you firefighters are a group of people worthy of respect. I hope the ladder I designed can help you save more people. I would also like to express my highest respect to all firefighters!"
The reason why Liu Lang gave this patent to the other party was not because he had too much money, but because he really felt that they were a group of respectable people. When the fire broke out, they were the first to rush to the fire scene to rescue the trapped people.
, this kind of courage is not something ordinary people can possess. During the September 11th incident fourteen years later, nearly a thousand firefighters sacrificed their lives in order to save other lives.
This is not only true for Americans, but also for Chinese soldiers. Usually they seem to keep strangers away, but when a disaster strikes, these people will definitely come forward. The disaster in 1998
The great flood is the embodiment of this spirit. I don't know how many soldiers died in the flood trying to rescue ordinary people. Liu Lang's contribution to them is really insignificant in the face of these.
Liu Lang did this willingly. Banks felt that this child deserved his respect, especially the other person's identity, which he found very rare. Liu Lang was a Chinese child, and he learned from Professor Hanks that he was not Chinese.
, is a native Chinese.
A Chinese has traveled thousands of miles to come to the United States. He has no self-interest, only benefits others, and contributes to the firefighting cause of the United States. What kind of spirit is this? This is the spirit of internationalism, this is the spirit of communism. A person's ability varies,
But as long as you have this spirit, you are a noble person, a pure person, a moral person, a person who has escaped from vulgar taste, a person who is beneficial to the people...
Well, Banks is not good enough to express Liu Lang's internationalist spirit in words, but he can understand the basic meaning and shows deep respect for this spirit.
Liu Lang, Professor Hanks, Director Banks and Makeda stood together and took a photo. Liu Lang and Director Banks also took photos when they signed the contract.
It’s already noon after finishing all this, and you haven’t attended any morning classes, but no one in the university cares whether you attend class or not. Besides, Liu Lang’s classes are full of randomness, and sometimes you can even see him in Arabic language classes.
.
Professor Claire was nowhere to be seen. Liu Lang ran to the library to read after lunch. It was not until around two o'clock in the afternoon that he found Professor Claire in his office.
"Professor, this is the information you gave me, I will give it back to you!"
"Oh, I gave you two months, and it's only been more than a month now. What's wrong? Can't you understand?"
"No, I already think I understand everything!"
Liu Lang smiled.
"Do you understand everything?"
Professor Claire was a little surprised.
"You can test me!"
Liu Lang said confidently.
"Okay, then I will test you now!"
"Let me ask you first, how to install the engine piston rings?"
"Well, there are generally three piston rings, two gas rings and one oil ring from top to bottom. There are direction marks on each ring. The side with the direction marks faces the top of the piston. The key points for assembly are: piston
The staggered position of the ring is the key factor that determines the sealing effect of the piston ring
, the opening of the first gas ring should be towards the side of the cylinder wall that receives less side pressure, which can slow down wear. If it is an integral oil ring, the openings of the three piston rings should be staggered 120o from each other; if the oil ring consists of 2 pieces
The oil scraper is combined, and the two air rings are staggered by 180
o, the two scraper blades of the combined oil ring are staggered by 180 degrees, and the upper scraper blades of the second air ring and the combined oil ring are staggered by 90 degrees."
Liu Lang answered directly.
Professor Claire's question is definitely not the original question in these materials. For example, this question in the materials is just an article about various problems with engine piston rings. This problem is included in it, but it is only mentioned briefly, and it is not fully
To expand on the explanation, Liu Lang was able to answer such complete questions because he understood these questions thoroughly and did not miss any point that he did not understand.
Professor Claire glanced at Liu Lang with an expression of surprise. What's going on with this little guy? Can he really understand these more than ten papers and lesson plans? He felt that even a student who had just become a Ph.D. could not do it.
at this point.
"Well said, it seems you are really thoughtful, but... let me ask you, how do you assemble the piston into the cylinder?"
"Okay, take a 4-cylinder engine as an example. The order in which the piston connecting rod assembly is installed into the cylinder is cylinder 1, cylinder 4, cylinder 2, cylinder 3. Rotate the crankshaft so that the connecting rod journals of cylinder 1 and cylinder 4 are at the lowest point.
Place the special tool on the outer circle of the piston ring, compress the piston ring until it is flush with the outer circle of the piston, and extend the big end of the connecting rod into the cylinder.
It should be noted here that during the installation process, the big end of the connecting rod should be supported by hand to prevent the connecting rod bolt from scratching the cylinder wall and crankshaft. Use a non-metallic rod to hold the top of the piston and push it into the cylinder.
Rod big end and connecting rod journal of crankshaft
After fitting, install the connecting rod bearing cap and tighten the connecting rod bolts to the specified torque. After all the piston and connecting rod groups are installed, rotate the crankshaft to see if there is difficulty in rotation or sudden looseness and tightness. If necessary, find out the cause.
……….”
Liu Lang immediately replied.
Professor Claire narrowed his eyes. Liu Lang's answer was almost perfect. He would definitely not be able to answer this level if he didn't fully understand the knowledge points.
