Every Day Upgrades the Monsters and Explosives Equipment

　　 Star City, Shonan University.

　　 The re-examination is generally divided into a written test and an interview. The written test will be conducted first, followed by an interview. At the same time, there will be a self-introduction in the oral part of the interview.

　　 The score of 92 for the postgraduate entrance examination is naturally not a problem in English, and the written test in the morning is also very simple for Lin Shu.

　　 Until the formal interview, it is the key to the beginning of the show.

There are five teachers sitting in the classroom. I have to say that Lin Shu, the first social person in the initial test, left a deep impression on the teachers at the scene. One is because Lin Shu’s undergraduate is from Shonan University, and the second one. It is because Lin Shu is a graduate student who retakes the exam three years after graduation, and his score is quite high.

　　 More importantly, there was an interviewing teacher who gave Lin Shu a class on mechanical principles.

　　 But when he was undergraduate, Lin Shu's performance was not particularly irritating. The truly outstanding academic master had already taken the place of undergraduate research. As for Lin Shu, the student during his undergraduate study can only be said to be above average.

　　 When Lin Shu entered the interview room, he recognized Jiang Yu, the teacher who had taught him "Materials Mechanics".

　　 Although Jiang Yu didn't have a deep impression of Lin Shu, he roughly remembered that he had taught this student, so the atmosphere at the interview site was quite good.

　　 At the beginning, Jiang Yu asked, "Lin Shu, you caught a thief on the bus before and said that you did not come from Xiamen University, but graduated from Hunan University?"

　　 Lin Shu was a little surprised, but Jiang Yu actually knew about it.

　　 After all, this was last year, and it had been for a long time. I didn't expect anyone to remember it.

　　 Lin Shu nodded.

　　 Jiang Yu nodded, smiled satisfied and nodded and said, "Very good."

　　 "How can I think about taking the postgraduate entrance examination after work."

　　 "The real reason is that I don't have any advantages with a bachelor's degree, so I want to further study and improve myself."

　　 Jiang Yu said with a smile: "Why don't you directly apply for a master's degree?"

Hearing this question, Lin Shu couldn't help shook his head and said honestly: "I have been working for three years after all. I think there may be some difficulty in the postgraduate entrance examination. "

　　 "You are the first in the first try!"

Zhou Yang, another male teacher next to 　　, said with a smile: "Your score is very high."

　　 This is not what Zhou Yang said deliberately, but made it clear. The professional score is 140, and its scores in various subjects are also quite high. Everyone present has brought many graduate students, so naturally they know what Lin Shu's score means.

　　 After a brief introduction, it is the questioning session.

　　 "I won't ask particularly difficult questions, just talk about the principle of six-point positioning."

　　 This question is a bit biased, but it's not too difficult.

　　 Lin Shu directly replied: "Using six constraint points arranged in accordance with certain rules to limit the six degrees of freedom of the workpiece, that is, complete positioning is called the six-point positioning principle."

　　 "Then what is over-positioning and under-positioning, are both allowed and why?"

　　 This question is a bit deeper.

Lin Shu thought for a while, and replied: "Under positioning is a positioning that has not been restricted in terms of the degree of freedom that should be restricted according to the processing requirements. Under positioning is not allowed. Because under positioning cannot guarantee the processing requirements. Over positioning is a part of the workpiece. Several degrees of freedom are repeatedly restricted by different positioning components. When over-positioning causes deformation of the workpiece or positioning components, which affects the machining accuracy, it should be strictly prohibited. However, when the over-positioning does not affect the machining accuracy, it is beneficial to improve the machining accuracy. , Can also be used."

　　...

　　 The other teachers here saw Shushi Lin giving answers very directly, and they were quite accurate, unlike some of the previous students who stumbled and went around, and did not answer correctly, and they all started to ask questions about Lin Shu.

　　 "You talk about the processing method of gears."

　　 This is easy. Anyway, Lin Shu has been working for three years, even if he didn't review it, he knew it.

Lin Shu quickly replied: "The forming method and the generative method are two. The forming method is mainly gear milling and tooth pulling, and the generative method mainly includes hobbing and shaping. The main difference between the two methods is that the machining accuracy of the generative method is higher. High, up to level 3. However, the production efficiency is relatively low. In addition, the generative method requires gear grinding equipment, and the production cost is relatively high."

　　 After hearing Lin Shu's answer, the teacher who asked the question couldn't help but laugh. Obviously, Lin Shu was still impressed by the production cost and production efficiency. This was also because of his work experience.

　　...

　　 Other instructors couldn't help but start asking questions about Lin Shu, wanting to see if they can ask Lin Shu.

　　 "What are closed loops, increased loops, and decreased loops?"

Lin Shu directly replied: "In the dimensional chain, the final ring formed in the process of processing or assembly is called a closed ring. If the change of the ring causes the closed ring to change in the same direction, the ring is an increasing ring. The change causes the reverse change of the closed ring, then the ring is a subtractive ring."

　　...

　　 "The difference between electric welding and gas welding?"

"Arc welding mainly uses the high-melt metal of the arc generated between the conductors to weld, and can weld metal materials of more than 3mm. UU reading www.uukahnshu.com gas welding uses the high heat generated by gas combustion to melt the script to achieve welding. For the purpose, it is used for all kinds of thickness, mainly used for welding thin materials and cutting metal materials."

　　...

　　 "What are the characteristics of the involute tooth profile?"

　　...

Lin Shu feels that he is facing several guard elders now, and must ask questions one after another through the guard elders, from mechanical processing, material mechanics, to various unpopular knowledge points. All of them seemed to want to get Lin Shu stuck at the second gate to prevent Lin Shu from entering easily.

　　 Fortunately, Lin Shu's cultivation skills are very deep, and he still has a certain degree of cultivation in the mechanical profession, at least for the time being, he is still able to deal with it freely.

Of course, this is also the case for these guarding elders. They still didn't directly kill Lin Shu. Until they clicked, they didn't leave Lin Shu a little retreat. They pressed on every step of the way. Most of the topics were within Lin Shuli's reach. , Did not ask from the mechanics of materials to aerospace.

　　 Jiangyu was quite satisfied with Lin Shu's interview. I have to say that Lin Shu not only has a solid professional foundation, but also has a lot of experience in actual machining. This is undoubtedly the advantage of Lin Shu's three years of work.

　　 Several guarding elders were naturally not just to deal with Lin Shu alone. Time was limited and most of the problems were overcome. Lin Shu could be regarded as ending the challenge of this level.

　　 As for the result, whether it can be cleared will be announced later.

　　 However, Lin Shu is still very confident that he can pass this level, and he does not feel that he is blocked by the guard elder.

　　 After the Wenguan challenge was over, Lin Shu was not surprised by the bones, and was immediately accepted as a close disciple on the spot, and Lin Shu also left in a hurry.

　　 does not take away a trace of cloud.
