Song Weize felt that he couldn't end it.

As the director of the R&D room, Song Weize is the chief examiner of this second session, and it is said that it is up to him to decide whether the answer is correct or not, but Niu Shilong gave the decision in advance, saying that the answer was wrong.

However, Song Weize knows that the plan that Qin Zhenhua said is also available, although even the factory does not have this kind of equipment, but in the world, this kind of frequency conversion governor has gradually entered the practical stage.

Although what Qin Zhenhua said is not the way in the answer, there are many ways to achieve a goal.

In this process, almost all the time it was Niu Shilong who spoke, Ma Panshan and Zhou Xuejun who were sitting on the rostrum almost didn't speak, and now, Song Weize asked Zhou Xuejun for help with hesitation.

If I directly say that Qin Zhenhua's answer is okay, isn't this refuting the face of Director Niu Shilong? Director Zhou, you should give a round!

However, at this time, Zhou Xuejun lowered his head and drank tea, and he made a statement that he had nothing to do with himself.

Suddenly, it was cold again.

Now in this examination room, there are hundreds of people in the audience, not to mention that there are hundreds of people, all waiting, Niu Shilong also felt that something was wrong after finding that Song Weize did not answer, wouldn't it, is this what Qin Zhenhua said?

"Director Song, can you proceed to the next question?" Qin Zhenhua asked.

With such a question, Song Weize can be regarded as finding a step down, simply, let's take the next question?

Song Weize wanted to turn this exam question backwards, but Niu Shilong quit, if you continue to take the exam, wouldn't it mean that Qin Zhenhua was correct just now?

Niu Shilong's mind was thinking rapidly, he was experienced, especially today, in front of so many people, he must not be ashamed.

At this moment, his eyes swept to the row of people on the side of the rostrum, and the circle of people there was almost all red-eyed and drowsy.

On the left side of the rostrum, there are the masters who are preparing to accept the second big competition today, and on the right side of the rostrum, are the people who made the exam questions, but now they can't help but doze off and stay up all night.

"Old Song, you take a rest first, Xiao Du, Xiao Du, come over and read the standard answer." Niu Shilong has found a way, no matter what, today's time, we must also judge that Qin Zhenhua is wrong, and let Du Youwen tell everyone this standard answer.

In short, Qin Zhenhua's inverter governor, even if it really works, is a wrong answer!

Du Youwen was so sleepy, from the beginning, he was dozing off below, and now, when Niu Shilong shouted like this, the people around him pushed him, and he stood up.

"What's the matter?"

"Xiao Du, come, read your standard answer."

Yesterday, Du Youwen left after being squeezed by Qin Zhenhua, as for today, he came to the scene of the big competition again, and heard Niu Shilong say that he wanted to let himself read the answer, so he was interested, so he walked up quickly, on the side table on the side, turned on the microphone above, and read.

"First of all, let's make the first calculation formula..."

Qin Zhenhua sat down, put his hands on his chest helplessly, looked up at the sky, and knew that he was going to do this, listen, it was stinky and long, in this way, he had to take the exam for half a day, ten people, and it would take five days to finish?

These contents were copied from the previous handouts, and now that they have been completely read, Du Youwen's sleepiness is also completely gone, it must be that Qin Zhenhua did not answer.

"Xiao Qin, do you understand? That's the standard answer, and if you answer that, it's not okay. Niu Shilong felt that he had regained face, and, to avoid making any more mistakes, he simply asked Du Youwen to continue reading the question: "Xiao Du, you can continue to read the third question." ”

"Okay." Du Youwen was about to turn the page, and at this moment, Qin Zhenhua spoke again: "Director Song, I want to ask, who will judge the assessment of today's big competition?" ”

Song Weize knew that today was not going to end well, there had to be a position, he looked at Ma Panshan helplessly, and Ma Panshan also opened his mouth at this time: "Today's big competition, let us open our eyes, the truth is all refuted, old Song, 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, standard answer, is no problem." Song Weize said, this is a standard answer copied from a book, how can it be wrong?

Hearing Song Weize say this, Niu Shilong had a smile on his face, but then he heard Song Weize continue to say the following words.

"However, the answer given by Qin Zhenhua is also valid, the frequency conversion governor is a speed regulation scheme for a three-phase asynchronous motor." Song Weize said.

Niu Shilong's face is ugly, so many people are looking at it, I said that Qin Zhenhua is wrong, you say this, don't you give me face?

Niu Shilong's face changed, so that Du Youwen saw it, and Du Youwen immediately understood: "This frequency converter governor is only theoretical, in fact, it can't be made at all. Didn't we say that practice is the only criterion for testing truth? ”

Niu Shilong was happy again all of a sudden, so it was, he was almost fooled, it turned out to be just a theory!

Qin Zhenhua, sure enough, you still lost!

Of course, at this time, it is necessary to reflect the level of the leader, and the people below cannot see that they are blindly suppressing Qin Zhenhua.

"Yes, we are now testing the actual situation, Comrade Xiao Qin is not bad, the theory is very solid, the future is in your hands, wait until a few decades, maybe this kind of device can appear in your hands, it is still worth encouraging, however, this question can't be considered a correct answer, Lao Song, what do you say?"

Song Weize is about to collapse, sandwiched between the two sides, not a person inside and out.

"Theory?" Qin Zhenhua shook his head helplessly: "Director Song, please find someone to go to the data room, on page 3 of the March last year's issue of "Industrial Technology and Prospects", there is a detailed introduction on it, the German machine tool industry has begun to use frequency conversion governors to control motors in a large area to achieve a comprehensive stepless speed regulation program. By the way, it is said that the country also intends to import similar machine tools, and it is estimated that it will be about the same for a few months. ”

Niu Shilong was petrified in an instant, this Qin Zhenhua actually said so conclusively, is there really such a thing? Although he didn't understand, Qin Zhenhua was full of confidence.

Niu Shilong glanced at Du Youwen again, so Du Youwen understood and immediately said: "This is impossible, even if there is, there are serious defects, after all, the waveform generated by the thyristor cannot match the waveform of sinusoidal alternating current at all." ”
