As the director of the R&D room, Song Weize was the examiner for this second session. Ordinarily, he should decide whether the answer was correct or not. However, Niu Shilong made the decision in advance, saying that the answer was wrong.
However, Song Weize knew that the plan mentioned by Qin Zhenhua also existed. Although even the factory did not have such equipment, internationally, this kind of frequency conversion speed regulator had gradually entered the practical stage.
Although what Qin Zhenhua said is not the method in the answer, there are many ways to achieve the same goal, but there are many ways to achieve the same goal.
During this process, Niu Shilong was almost always speaking. Ma Panshan and Zhou Xuejun, who were sitting on the rostrum, were almost silent. Now, with hesitation, Song Weize asked Zhou Xuejun for help.
If I directly say that Qin Zhenhua’s answer is correct, wouldn’t this be refuting Director Niu Shilong’s face? Director Zhou, you can help smooth things over!
However, it happened that Zhou Xuejun lowered his head to drink tea at this time, showing his attitude that it was nothing to do with him.
Suddenly, it was quiet again.
Now in the examination room, there are at least hundreds of people in the audience, all waiting. After discovering that Song Weize did not answer, Niu Shilong also felt that something was wrong. Could it be that what Qin Zhenhua said is really possible?
"Director Song, can you move on to the next question?" Qin Zhenhua asked.
With this question, Song Weize finally found a way out. Why don't we take the next question?
Song Weize wanted to turn this test question backwards, but Niu Shilong quit. If you continue to take the test, wouldn't it mean that Qin Zhenhua was right just now?
Niu Shilong's mind was thinking rapidly. He had rich experience. Especially today, in front of so many people, he must not be embarrassed.
At this moment, his eyes glanced at the row of people on the side under the rostrum. Almost all of the people there had red eyes and were drowsy.
On the left side of the rostrum are the masters who are preparing for the second competition today, and on the right side of the rostrum are the people who are giving the exam questions. However, now they can't help but doze off, having stayed up all night.
"Old Song, please take a rest first. Xiao Du, Xiao Du, come here and read the standard answer." Niu Shilong finally found a way. No matter what, Qin Zhenhua must be judged to be wrong in today's game. Let Du Youwen
Let me tell you this standard answer.
In short, Qin Zhenhua’s variable frequency speed regulator, even if it works, is still a wrong answer!
Du Youwen was really sleepy, and he had been dozing down below from the beginning. Now, when Niu Shilong shouted, the people around him pushed him, and he stood up.
"What's up?"
"Xiao Du, come here and read your standard answer."
Yesterday, Du Youwen left after being squeezed out by Qin Zhenhua. As for today, he came to the competition site again. When he heard Niu Shilong said that he would read the answers, he became interested, so he quickly walked up and stood on the side.
On the table, I turned on the microphone above and started reading.
"First, we need to carry out the first calculation formula..."
Qin Zhenhua sat down, put his hands on his chest helplessly, and looked up at the sky. He knew he was going to do this. Listen, it's smelly and long. In this way, he would have to take the exam for a long time alone. Ten people would not be able to do it.
Five days to end?
These contents were copied from the previous lecture notes. Now that they have been completely read, Du Youwen has no sleepiness at all. It must be Qin Zhenhua who did not answer the questions.
"Xiao Qin, do you understand? This is the standard answer. It's not okay for you to answer like that." Niu Shilong felt that he had regained his face, and to avoid making any more mistakes, he simply asked Du Youwen to continue reading the question: "
Xiao Du, please continue reading the third question."
"Okay." Du Youwen was about to turn the page, but at this moment, Qin Zhenhua spoke again: "Director Song, I would like to ask, who will judge the assessment of today's competition?"
Song Weize knew that today was not going to end well. He had to take a stand. He looked at Ma Panshan helplessly. At this time, Ma Panshan also spoke: "Today's competition is an eye-opener for us.
, The truth is all refuted, Lao Song, please tell me, how to judge these two answers?"
One is the standard answer, and the other is the simple answer given by Qin Zhenhua. How to determine it?
"This, the standard answer, there is nothing wrong with it." Song Weize said, this is the standard answer copied from a book, how could it be wrong?
Hearing what Song Weize said, Niu Shilong smiled on his face, but then he heard Song Weize say the following words.
"However, the answer given by Qin Zhenhua is also valid. The variable frequency speed regulator is a speed regulation solution for a three-phase asynchronous motor." Song Weize said.
Niu Shilong's face looked ugly. With so many people watching, I even told Qin Zhenhua that this question was wrong. By saying that, weren't you not giving me face?
The change in Niu Shilong's face caught Du Youwen's eye, and Du Youwen immediately understood: "This variable frequency speed regulator is only theoretical. In fact, it cannot be built at all. What we are testing now is practical, and
It’s not theory. Didn’t we say that practice is the only criterion for testing truth?”
Niu Shilong suddenly became happy again. It turns out that was the case. He was almost deceived. It turned out to be just a theory!
Qin Zhenhua, as expected you still lost!
Of course, at this time, the level of a leader must be reflected, and the people below cannot see that he is blindly suppressing Qin Zhenhua.
"Yes, we are testing the actual situation now. Comrade Xiao Qin is not bad. His theory is very solid. The future is in your hands. In a few decades, maybe this kind of device will be in your hands.
It's worth encouraging to show up, but this question can't be considered correct, Lao Song, what do you think?"
Song Weize was about to collapse. He was caught between two sides, and he was no longer human inside and outside.
"Theory?" Qin Zhenhua shook his head helplessly: "Director Song, please find someone to go to the data room. There is a detailed introduction on page 3 of the journal "Industrial Technology and Prospects" in March last year. The German machine tool industry has already begun.
Frequency converters are used on a large scale to control electric motors to achieve a comprehensive stepless speed regulation solution. By the way, it is said that the country is also planning to import similar machine tools. We don’t have to wait for decades. It is estimated that it will be almost done in a few months.”
Niu Shilong was petrified in an instant. This Qin Zhenhua actually said it with such certainty. Could this thing really exist? Although he couldn't understand it, Qin Zhenhua was very confident.
Niu Shilong glanced at Du Youwen again, so Du Youwen understood and immediately said: "This is impossible. Even if it is possible, there are serious flaws. After all, the waveform generated by the thyristor cannot match the waveform of the sinusoidal alternating current."
