"Oh, it's not as good as you imagined..." Hao Shuai next to him thought for a long time before he started writing.

Zhang Yifu shook his head, cleared the external interference, and looked straight ahead and thought. Although he knew everything, he had to simplify the language and description, and only talked about the key points. After all, the person who was marking the papers was the leader in charge of human resources, and he might not be able to understand it if he wrote too professionally. Some people present had even started drawing pictures and writing formulas, which showed that he had memorized a lot of books, which was obviously unscientific.

On the podium, the old professor smiled slightly and said to Liu Jian.com next to him: "I've read the pen, Director Liu, is this question too simple?"

"Haha, I'm not studying this major, and I can't raise any difficult questions." Liu Jianwang glanced around and happened to see Zhang Yifu, who was staring blankly. He whispered, "Professor Chen, isn't there anyone who hasn't started writing there?"

When the old professor followed the direction, he saw that it was Zhang Yifu, so he could only sigh: "You said Zhang Yifu, his score was not low when he entered school, but he relaxed afterwards, but he always passed the exam. He was smart and did not work hard enough. At the critical moment, he finally couldn't get through the edge. What a pity."

"It's indeed a pity..." Liu Jianwang sighed at Zhang Yifu, who had a very outstanding image. He had seen too many people who were smart but unwilling to work hard and had no ambitions. Even in ministries and commissions, there were people who were scattered like this. Such people must not give him a comfortable environment, and they must force him to work hard.

Zhang Yifu didn't know that the simple conversation between the two bigwigs on the stage had basically announced his death penalty, and the only thing that could solve the dilemma was probably the piece of paper in his hand.

After thinking for half a minute, Zhang Yifu finally started writing and used the simplest words he could extract to describe the working principle of a thermal power plant-

[Thermal power plant generates power through the joint action of boilers, turbines and generators.]

【1: Coal is burned by conveying tracks into the boiler to produce high-temperature and high-pressure water vapor to drive the turbine to rotate.】

【2: The turbine drives the generator to rotate, and the generator generates electricity according to the basic principle of cutting magnetic inductive wires.】

【3: The three-phase alternating current generated by the generator is led out and sent to the power grid through the end leads to complete the power generation process.】

[4: After the used steam is purified and liquefied by chemical means such as condensation and deoxygenation, it is reorganized into the boiler, heated again to the steam state, and circulates to do the work.]

[Supplement: According to the different power generation energy, thermal power plants are also divided into oil-fired power plants, natural gas power plants, etc. The principle remains unchanged, but the boiler structure is different according to different raw materials.]

After answering this question, it took less than three minutes. Zhang Yifu looked around with his light. Most people were still writing quickly, and they didn't know whether they were placing the thermal formula or the generator circuit diagram.

While in a daze, he only heard a cough and looked sideways. It turned out that Xia Xue had finished answering and pushed the paper to the side, pushing Zhang Yifu's vision.

Is it still a matter of gratitude?

But Zhang Yifu just whizzed and shook his head gently, indicating that he didn't need it at all.

"It seems that he gave up on himself." Xia Xue murmured, took back the paper, thought for a moment, and began to make some necessary supplements.

On the stage, Liu Jianwang looked down at his watch. He heard the sound of some people tearing the second piece of paper, but he shook his head helplessly. No one asked them to draw circuit diagrams. Even if they drew them, Liu Jianwang would not understand them. People who are skilled are a bit pedantic and stubborn after all.

He couldn't help but look at Zhang Yifu who had just paid special attention. This kid was the opposite. He started writing at the latest and stopped writing at the earliest. I don't know if it was because he had no water in his stomach or if he had understood the purpose of the assessment. He had to take a good look at his paper later.

During the five minutes, Liu Jianwang no longer cared about the classmates who were working hard and said, "Okay, it doesn't matter if you haven't finished it. This is not an exam, I just have a little understanding of everyone."

After saying that, he directly raised the next question: "Please listen to the second question - if a city faces a problem of power shortage, please propose a solution and briefly describe the reasons and advantages and disadvantages."

Everyone's thinking has not yet broken out of the basics of power generation, and the second question has come to mind. Unlike the first question, the second question does not seem to be in the textbook. Rather than a professional question, it is more common sense questions or management questions. You may be able to answer this question if you don't have a class in one day. On the contrary, you may also be able to answer it very ordinary when you study hard every day.

Some people quickly pick up their pens, while others fall into confusion.

On the surface, Zhang Yifu seems to be one of the confused people, but he is actually thinking more. People in this era are more honest. After others have asked questions, they will only try their best to think about the steps to solve the problem. Zhang Yifu knows that Liu Jianwang is a manpower worker, not like a person who is dying to learn skills. To solve his questions, one should think from the starting point of the questioner's assessment rather than technical details.

The first question is, Liu Jian.com’s purpose is to see if you understand the basics and whether your brain understands it. That’s all.

The second question is whether the practical application knowledge that you have not passed through, and the book cannot be easily solved. It seems very simple, but in fact there is a secret topic hidden here. Liu Jianwang said it clearly, and at the end he mentioned "Please briefly describe the reasons and advantages and disadvantages." The advantages and disadvantages are compared, that is, there is absolutely more than one way to solve the problem of power shortage. It requires comparing several ways to compare with each other and making judgments.

At this level, it is actually a professional question, and it is a professional question in actual work, a professional question in management direction and overall situation. Even students majoring in electricity will be very difficult to answer perfectly; on the contrary, an old electrician who graduated from elementary school may be able to answer easily.

Zhang Yifu suddenly felt very embarrassed. He had been working in the power plant for so many years. Is it considered cheating to come back to answer such questions with the intimate students?

【There are three general solutions】

[First, increase power supply capacity and build new power plants to make up for the power consumption gap. The advantage is that it can directly increase the power generation, and the excess power can also be incorporated into the power grid to solve the urgent needs of other cities; the disadvantage is that the power plant construction cycle is too long and cannot solve the immediate problems immediately, which will delay the production and life of power-deficient cities.]

[Second, regional power transmission. The advantage is that it is fast to take effect. After building high-voltage transmission lines, you can immediately obtain electricity from surrounding power plants; the disadvantage is that the national power supply is in a tight state, so it is difficult to surpass one or the other.]

[Third, use electricity in an orderly manner, balance the power supply through peak-by-peak electricity use and pull-out power limit, especially to stabilize electricity consumption during peak periods; the advantage is that there is no need for external forces, and the city can be solved immediately; the disadvantage is that it is not a solution to the symptoms but not the root cause, which is not good for economic development, and at the same time greatly affects the order of production and life.]

[In summary, there are always inappropriate solutions. Three methods can be used together. On the one hand, building a power plant, increasing power transmission, and limiting part of the power consumption until the new power plant is completed, the power shortage can be solved smoothly.]

After Zhang Yifu finished answering the question, he had been a long time since the regulations were used and he had already started to be narcissistic. He was afraid that he had used too many essential professional vocabulary and was too high to make his leader unable to understand it.
