Chapter 89
Chapter 89 I will be firm and get constant
Then Mu Rong took up a circuit board: “You will participate in the national semi-finals next week. The theoretical test questions for the semi-finals will still be the national paper, and the experimental questions will be arranged by each province. Although in the semi-final the theoretical test questions account for 160 points, the experimental questions only account for 40 points. , But the next week I will focus on training the experimental link, which is the weakness of most of you.”
Next, enter the training of experimental operation.
If Mu Rong talks about theoretical questions, Shen Qi generally does not meet up with the big army. He will ask Mu Rong alone for theoretical knowledge, and then go home to do the questions himself.
You still have to come to the school laboratory to do physics experiments. After all, the school laboratory has complete equipment and complete equipment, and it uses public water and electricity.
Some experiments will also use compressed air. Generally, who would install compressed air pipes in their own homes?
Compared with the theoretical knowledge he has stored, Shen Qi is very clear that experimentation is not his strong point, so he joins the large army and conducts experiments.
Mechanics experiment, acoustic experiment, optical experiment, electrical experiment, magnetic field experiment…Practical operation is in progress.
A week passed quickly, and in a blink of an eye, April, the CPhO rematch is about to begin.
The schedule for the semi-finals is to take theoretical questions first, with a full score of 160.
Test the experimental part a few days later, with a full score of 40.
The total score of theory + experiment is the final score of the semi-finalists.
Based on the total results of the semi-finals, each province recommends the best players to participate in the national finals. Generally, a province selects the top ten players in the first prize of the semi-finals to go to the national finals.
The three provinces of southern Hunan, northern Hubei, and eastern Zhejiang are more powerful. There will be no less than 20 players sent to participate in the national finals.
Some provinces attach importance to the college entrance examination, and some provinces attach importance to subject competitions. In fact, the number of competitive provinces and the competitive provinces are almost the same, there are just a few.
Xiang, Hubei, and Zhejiang are very good in mathematics and physical competitions, but these three have never had a mathematics and physics double national championship contestant. The double gold medalists of IMO and IPhO have never appeared in the world.
“Physics, physics, don’t be too arrogant, I’m just a person who doesn’t do it. If I do, I will max out you. 199 points, damn, what I hate the most is the full score minus one point. You are embarrassing me, Shen Qi, right? ?”
Shen Qi simmered, CPhO’s preliminary round has already missed, and the rematch must not repeat the same mistakes.
“Oh, Shen Qi, are you irritated?” Mu Rong chatted with Shen Qi while packing up the experimental equipment.
Shen Qi carefully disassembled a set of glass lens instruments: “It’s okay.”
“Obviously, you are irritated, do you have obsessive-compulsive disorder? When you see imperfect numbers like 99, 149, and 199, you will go crazy, right?” Mu Rong asked.
Shen Qi shook his head: “No, I won’t be irritated with a 999 level.”
The CPhO rematch will be held tomorrow, and Mu Rong completed the last experimental class before the game.
Shen Qi and Lin Xingyu stayed in the laboratory to help Mu Rong pack up the experimental equipment.
“Shen Qi scored 199 in the preliminary contest and Lin Xingyu scored 138 in the preliminary contest. Two handsome guys, you are my trump cards.” Mu Rong packed the last circuit board and said with a look of encouragement.
Lin Xingyu said with trepidation: “No, no, no, I am not, Shen Qicai is the trump card. I am a Ma Tsai, Mr. Mu’s Ma Tsai.”
Shen Qi scored 199 points in the preliminary test and Lin Xingyu scored 138 points. They ranked first and second in the team respectively. Of course, the gap between second and first is a bit big.
Mu Rong has taken over this sports team for a few months. After the preliminary round, she was a little disappointed. If she hadn’t recruited Shen Qi into the team, it would be difficult for her to have a dozen guns.
Even if Shen Qi was recruited into the team, the overall strength of the Second Middle School Sports Team was far from Mu Rong’s expectations.
Perhaps Mu Rong was too demanding of herself. After packing up the experimental equipment, she didn’t let Shen Qi and Lin Xingyu go, and gave them three real questions from the previous CPhO national finals, one each in thermodynamics, optics, and electricity. , Are very representative.
“Okay, let’s stop here, take a break tonight, and have a big job tomorrow, and go straight to the national championship!” Mu Rong is very confident in Shen Qi’s promotion to the national championship, and Shen Qi is her absolute trump card. The biggest card in the deck is Lin Xingyu, and Mu Rong also hopes that Lin Xingyu can perform miracles.
“Well, Teacher Mu, I will definitely work hard, I must advance to the National Finals!” Lin Xingyu was like a chicken blood.
“Mr. Mu also rest early.” Shen Qi didn’t make any promises, but calmly said goodnight to Mu Rong.
“A few more people enter the national finals, I can also give out more bonuses, come on.” Mu Rong asked Shen Qi and Lin Xingyu to go first, and she finally locked the door of the laboratory.
Shen Qi and Lin Xingyu walked to the school bicycle shed.
“Does Teacher Mu have any knowledge?” Shen Qi asked.
“Yes!” Lin Xingyu answered without hesitation.
“Does Mr. Mu give the lecture well?”
“it is good!”
“Is Mr. Mu beautiful?”
“nice!”
“Ms. Mu is short of money?”
“Lack!” Lin Xingyu was unwittingly caught up in a routine. He realized that he had said something wrong, and quickly explained: “How do I know if Teacher Mu is short of money?”
“How do I feel that Teacher Mu is short of money?” Shen Qi felt this way. When she was alone with Mu Rong last time, Mu Rong said that she didn’t have money to maintain her car.
No, no, the salary and benefits of the teachers in the second middle school are not low. Teacher Mu is good at teaching, and she has the title of Dr. Yan University to support her appearance. She goes out and brings any physics training class, so she can do it in a small day. The beauty of the past.
Lin Xingyu glanced at the west, and then whispered: “I heard that Mr. Mu’s house and car are all provided by her alone. It is very hard.”
“You have heard a lot.” Shen Qi walked to the bicycle shed, said goodbye to Lin Xingyu with his bicycle, and went home.
The next morning, Mu Rong led the team to the City No. 6 Middle School, where the CPhO rematch theory test was held.
The re-examination theory test is also 3 hours, from 9:00 to 12:00.
jingle bell, 9 o’clock exactly, the exam begins.
Shen Qi in the No. 6 examination room got the re-examination theory paper, and also quickly scanned the whole question first.
There are eight questions in the theory test paper. The first question is a fill-in-the-blank question, and the next seven questions are all calculation questions. The total score of the roll noodles is 160 points.
The first fill-in-the-blank question is a warm-up question, with the lowest score of 12 points.
Although it is a warm-up question, this fill-in-the-blank question with the lowest score is definitely not a free question.
“This… really is a rematch, and the difficulty has increased.” Shen Qi had a good rest last night, and today he will not doze off, nor dare to doze off.
Because of this warm-up fill-in-the-blank question in the rematch, it seems to Shen Qi that it is a bit horrible to send the proposition, and there is a slight mistake, even the 199 preliminaries of Shen’s big brother may die.
The title of this question is:
“Shen Kuo of the Northern Song Dynasty wrote “Mengxi Bi Tan”, which contained: In the sea of Dengzhou, there are clouds from time to time, such as palaces, terraces, castles, figures, carriages, horses, and crowns, which can be seen through the calendar.”
“The formula is as follows: n^2(y)=n0^2+np^2(1-e^-αy
“Let x=0 (x is the horizontal axis), height y=H, and n0 be the refractive index at y=0. np and α are constants, depending on the temperature distribution.”
“The trajectory equation of the light propagating in the air is ______”
The wood is there, the question surface is over here, not even a schematic diagram is given.
“This…” Shen Qi Ning thought with his eyebrows, five minutes later, he didn’t dare to write.
Obviously, this is an optical problem.
Don’t think that people who engage in physics competitions don’t need to learn Chinese. The purpose of learning Chinese is to ensure that you can recognize the full text of the topic.
After acknowledging the words written by Quan Shen Kuo thousands of years ago, a simple analysis is required. What did Shen Kuo Shen Gong, the chief scientist of the Northern Song Dynasty describe? Can it be explained from a physical point of view?
If you know Chinese characters and some common sense of physics, then it is not difficult to understand the passage Shen Gong recorded in his collection of essays “Mengxi Bi Tan” in the Northern Song Dynasty. Shen Gong described the phenomenon of the mirage in words.
I believe that most high school students can deduce a mirage from the first paragraph of this fill-in-the-blank question.
But the following description of pure physics, I am afraid that only a few high school students can understand what it means.
Do not!
The first question is definitely not a free question!
This question is quite difficult, don’t be fooled by its humble appearance of 12 points, it has the potential to die!
Shen Qi didn’t dare to care about it He reviewed the question carefully again, and ten minutes passed.
At this hour of the preliminary contest, Shen Qi has broken 15 consecutive questions.
At this hour of the rematch, Shen Qi didn’t write a word.
Fill-in-the-blank questions do not give you the opportunity to explain in detail, either 12 points or 0 points, there is no so-called step points.
“Hum hum hum hum ……” And five minutes later, Shen Qi smiled issue crooning, this is his offensive prelude.
Shen Qi found his way of thinking, and even found a rare opponent: “Ha ha, ha ha ha… the teacher who gave the test is very naughty, right, that’s right, this is the style of a regular physics teacher. Shen Kuo, Shen Gong, Lao Ancestor, you are the first-generation scientist of our old Shen family. Don’t worry, I will not shame the old ancestor.”
The mirage is simply an optical phenomenon.
The light rays are significantly refracted by air layers of different densities, and the distant scenery is displayed in front of people in a magical way.
There are not many people who have seen the mirage with their own eyes. This requires fate.
But it doesn’t matter, we can feel the dream scene of the mirage by doing physics problems.
Shen Qi writes and draws on the draft paper with a pen.
Air, no direction.
Parallel, like divided clothes.
Thin layer, refraction seeps out of wings.
My angle, through the normal chest.
Flying θ, forcibly endure the injury.
fled, dx’s shotgun.
Dear light, the integral of beloved.
I will be firm and get constant.
……
, what a beautiful physical movement.
Shen Qi started to sing while typing the draft.
Doing questions is not that boring, so why not treat it as a kind of fun.
