Chapter 230

Examinations are always relative.

The same paper, from the perspective of different people, has different feelings.

For example, Li Zheng, after doing the first two mechanics problems, the biggest feeling is that this is a "calculus competition for middle school students".

There is no way, because the mechanical problems are so classical that it is difficult to make any breakthrough in concept and thinking, so we have to do something in mathematics.

In Shi Yang's eyes, it is another world.

First of all, it has been 20 minutes since the exam began. He has not read it. There is no doubt that before it becomes a physics problem, it is first a reading comprehension problem.

Chinese less than 120 points, all out!

When Shi Yang got here, his eyes were dull and he died.

Only those who are careful in mind, have a dual discipline in Chinese and physics, and have excellent endurance. Even if the author is not segmented, and has no comma, can he be brave enough to read it.

And Li Zheng is such a person.

In about two hours, he hit the final question -

[lightning is one of the most magnificent natural landscapes on earth 】

(be ready to start ~)

[gamma ray bursts Lightning cloud discharge Small ice crystals Cloud to ground lightning]

(do you understand, brother? I don't know. Read it several times.)

Take advantage of Measurement of electric field in a cylindrical space lightning cloud 0.15MVm…… 】

[the radius is 2.5km, and the height is 1.0KM 】

[known vacuum dielectric constant ε = 】

(refueling, you can)

[in the process of electrification, the charge at both ends of the lightning cloud will increase exponentially with time 】

[when the surface electric field is greater than 1.0kvm, cloud to ground lightning will occur 】

[the lightning cloud moves down slowly from the high altitude until it 】

[try to estimate the surface electric field intensity directly below the lightning cloud. 】

(there is one saying, I really don't intend to let you understand. Even if you understand, it's just that you think you understand, but in fact you don't understand it. Even if you really understand, don't worry, you can't do it.)

Even Li Zheng was a bit broken when he read this.

The horror is, this is only 13 of the problem.

Li Zheng tried to scan the back five questions first.

He seems to see strange words like "ball lightning", "ionosphere", "halo expansion" and "microwave bubble".

It's like reading hard core science fiction.

The problem is, in science fiction, there are usually scientists to do this without the reader's trouble.

And this time, I'm sorry, you're a scientist.

Don't you like physics? Isn't your ideal to create the future of mankind?

Come on, here's the calculator. Here you are.

Most people read this question, have a feeling of broken dreams.

Even Li Zheng, the hand holding the pen also can't help but tremble, repeatedly reading the topic, the sweat on his forehead is more and more.

Even if the physics score is close to 350.

He has done almost all the physics problems in the world.

But at this time, he had a kind of original "top-level papers, usually need several people to work together for a month to master one or two."

"This is the lack of learning ability and the gap between problem-solving machines and academic talents."

"And this question tests this ability."

"It can be said that this topic is a small paper, a primary school achievement."

"Whoever can chew and understand clearly within the specified time will get the 70 points, and the one to be selected in the physics competition."

"For this question, it is a test of your own thinking strength and understanding ability. No matter how much training you take, no matter how many famous teachers give advice, there will be no effect."

"On the contrary, students who are self-taught have more advantages."

Two teachers, a man and a woman, nodded repeatedly when they heard that. If it was true, they would accept the letter.

"It's Mr. Sun, who sees it better than us."

"I almost forget that this kind of examination is to select academic talents."

"Sun Xiubin" only raised his hand and laughed.

"Of course, this problem also has its problems."

"It should have been in the finals."

"I'm afraid the students will not be able to cope with this kind of question in the second round."

His voice has just dropped.

Shi Yang raised his hand suddenly, his face full of anxiety.

Different from Li Zheng.

Every time he raises his hand, he really wants to do it.

In some ways, like Li Zheng and Lin Yujing, he seems to have returned to the original origin.The starting point where all the shit comes out.

……

At twelve o'clock sharp, the bell rings.

No one handed in the paper in advance.

It was Li Zheng who wrote the seventh question three minutes ago.

And there's no guarantee.

"Sun Xiubin" and others received the papers and announced the end of the examination.

The whole classroom was filled with wails of grief and indignation.

"Shit!"

"I was sad last year. Why is TMD more difficult today?"

"The seventh question, what kind of B thing?"

"The third problem is the electromagnetic gun. I'm so fucked up in my head that I'm in a mess."

"The second question is abnormal. Has anyone solved it?"

"After three years of preparation, it's really one day tour..."

"It's over, it's over, it's all over..."

It's different from the girls who failed in the exam.

The boys didn't cry.

Either scold or daze.

Only Li Zheng, long hair monster, Shi Yang this continuous look at the trio, still relatively stable.

Shi Yang's stability is mainly due to the emptying of his stomach and his lack of strength.

Secondly, he came for a day tour, and there was no pressure or expectation.

He turned around and leaned on the table and said to Li Zheng through the hairy Monster: "cool, Zheng..."

Before Shi Yang finished speaking, he sat up again.

From the appearance point of view, he Zheng elder brother, absolutely forced is cool.

I don't know when the school uniform was taken off, and the sleeve of the shirt inside wanted to be rolled to the shoulder.

The hair was wet, too. It was like a football match.

On the face, is also a pair of absorbed dry expression.

"Cool..." Li Zheng raised his arm, until now his hands are trembling, "this question, enough strength."

"Mmm..." Shi Yang swallowed his saliva and said, "I've made you do this This question is really OK. In this way, I've done half of it. Maybe I'll have a chance to make a dragon ball? "

"Stop beeping..." Li Zheng fluttered to pack things and said, "I went to find Lin Yue Jing to have dinner."

"Take a brother." Shi Yang rubbed his stomach and said, "my stomach is empty, no combat effectiveness."

"Go back and eat where it's empty." Li Zheng scolded.

"No, brother. I really want to take part in the problem-solving. I will never talk about you and other girls."

"Shut up!" Li Zheng turned his head and said, "well, now tell me the answers to the second and seventh questions. If it is reliable, you will be included."

"Well, that's right." Shi Yang laughs, "these two questions Laozi basically did not write a word."

"And the face to say." Li Zheng disliked to wave his hand, "go back to review the competition, not everyone can go to the problem, at least the seventh question to make some clues."

"The seventh question..." The hairy monster, who had been staring at the play, suddenly thought of something and said, "I remember, measuring the volume of a helium balloon is 380m

Li Zheng's eyes glared: "are you talking nonsense? My result is 1900m 3. "

"Ha..." Long hair strange silly ground knead the back of the head, "should be you wrong."

“？？？” Li Zheng's eyes widened.

Should I be wrong?

Young man, for so long.

Only, one person, dare to talk to me like that.

Just when he was about to say something, the hairy monster suddenly punched: "I know. You should have miscalculated the density 12 kilometers away from the ground. Shouldn't it be 1.53?"

“？！” Li Zheng's eyes can be even bigger.

"It's really..." The long haired monster waved his fingers and said with a smile, "think carefully, is it careless to calculate LN in front?"

Li Zheng was so surprised that he took out the draft paper and examined it.

Soon.

"Ah Li Zheng was angry and hugged his head, "how stupid!"

"Don't worry, don't worry..." The long hair monster waved his hand and comforted him, "is it true that the fierce teacher just reminds you that there are still 10 minutes to finish the paper and disturb your rhythm?"

“……” Li Zhengmu turned his head and his eyes couldn't be bigger.

This force, clearly 80% of the time in a daze, even the pen did not mention a few times

Thinking of this, Li Zheng's mind was tense.

Is This is mental calculation?!

This complexity So many calculus

You don't have to be a champion, can you?

This force, so young, looks like a junior high school student

How can we compete with the champion in several competitions

Thinking of this, Li Zheng's scalp gradually numb, word by word, wooden mouth: "you It's called What What... "With a smile, the long haired monster stretched out his right hand: "Gui Jian Feng. Yes, it's the return, the meeting, and the wind. "
