"Yes, yes, Brother Xiaoshan, tell me about it. Meng Xiaoqing couldn't ask for it.

Gu Wenna stared at Zhao Qingshan, she was quite curious about Zhao Qingshan.

Chen Yuyang is even more curious about Zhao Qingshan, he and Meng Xiaoqing are small, friends for more than ten years, Meng Xiaoqing's "brother" is his "brother", where did this "brother" come from?

The calmest is Lin Yuewei, who maintains an appropriate level of curiosity, with her palms on her cheeks, as if she is thinking.

Zhao Qingshan originally just wanted to tutor Meng Xiaoqing alone and send Meng Xiaoqing to a better university, but he had a wish.

But the situation has changed, and there are three more classmates.

Then Pinduoduo, Zhao Qingshan explained: "Let me say a sentence, you can experience, The manager allowed him to remain there, although it was not permitted." ”

Gu Wenna savored it, and then suddenly realized: "The manager allowed him to stay there, although the rules at this time did not allow it...... I understand, I got it!"

The classmate is really smart and can understand it at one point.

Extracurricular tutoring is also divided into several stages, instilling, reinforcing and allocating.

These students are in the strengthening period and the point allocation period, so they don't have to be exhaustive, they just need to be promoted point by point.

After obtaining Zhao Qingshan's consent, Meng Xiaoqing disclosed a secret: "The master who called me is Brother Xiaoshan." ”

"I knew that there must be a master behind Meng Xiaoqing, it turned out to be Brother Xiaoshan!" Gu Wenna smiled, and her confidence doubled.

Chen Yuyang suddenly realized: "Xiaoqing's set of English materials was written by Brother Xiaoshan, right?"

Lin Yuewei put forward a small expectation: "I really want to see a full set of English materials, Meng Xiaoqing always hides them." ”

Zhao Qingshan smiled and said: "It is very gratifying for several of you students who have good relationships to spontaneously organize extracurricular study groups to actively discuss and encourage each other in certain subjects, and I support it very much." I took the college entrance examination in '82, and we studied English at that time, but the English score was not included in our provincial college entrance examination score, that is, I did not take English in the college entrance examination room. ”

"There is a senior brother named Yu Minhong at Yenching University, he is a foreign language learner, he is well-known in the Wudaokou area, and often organizes English study classes. The 36 pages of English information I have written are technical, and it depends on the individual what kind of help it can bring to you. ”

"Mimeographing is troublesome, I suggest dividing these 36 pages of information into three, Chen Yuyang, Gu Wenna, and Lin Yuewei take them back and copy them in turn, within a week, each of you will get a complete piece of information, and in the process of hand-copying, you can also deepen your memory. ”

Zhao Qingshan proposed this, and all the students agreed: "Thank you, Brother Xiaoshan!"

Meng Xiaoqing took out 36 pages of hand-copied materials, divided them into three parts, each with 12 pages, and handed them to the three students.

Each page is densely occupied by English letters and a small number of Chinese markings, and Zhao Qingshan's handwriting is quite stylish, English Yan tendon, Chinese willow bone.

Gu Wenna couldn't help but admire: "Brother Xiaoshan is such a beautiful word." ”

Lin Yue said with a smile: "Well, people are like their words, vigorous and powerful, and the rectangular Q is just right." Brother Xiaoshan has worked hard, thank you again. ”

"Kobayashi-san is really humorous. Zhao Qingshan admired Xiao Lin's sense of humor, and he said: "I hope you keep this English material confidential, it is a secret between the five of us, and the level of secrecy is no less than that of the Clementino Library." ”

Lin Yuewei's eyes lit up, and then he sighed: "I just fell in love with Borges, but he left." ”

Borges's works have only been translated into Chinese in the last two years, and in the mid-to-late eighties, there were hundreds of schools of thought in the Chinese literary scene, and there were all genres, realism was still the main force, and the stream of consciousness became popular at an incredible speed.

In the era when there is no Internet, young people mainly draw spiritual food through books. The exchange of Zhao Qingshan and Lin Yuewei's stream of consciousness puzzled the other three, and Lin Yuewei's reading range was obviously wider.

Chen Yuyang, Gu Wenna, and Lin Yuewei solemnly promised that I would abide by the rules of the organization, keep the secrets of the organization, never betray the organization, and under the strong leadership of the study group with Comrade Zhao Qingshan as the core, I fought against the water, squeezed across the single-plank bridge, and won the battle of the college entrance examination.

The study continued, and at four o'clock, Meng Xiaoqing announced that he was disbanded, and his family was about to return.

Everyone went back to their respective homes and struggled for their own futures.

The test of 945 steel is still carried out in an intense and orderly manner, and the test at this stage is like solving a system of multivariate equations, and the unknown numbers are C, Cr, Mn, Mo, Si, S, Ni......

At present, it can be determined that the C element content in 945 steel should be 0.10~0.14%.

What kind of values should be taken for various alloying elements needs to be further solved by engineers.

The 180-kilogram small furnace is burning, and the word "small" is actually too large, and the appropriate word should be pocket-sized.

The pocket-sized test slabs are put to the test in a pocket-sized furnace, and after the slabs are rolled by the ∅ 360 hot rolling mill, various test data are available.

Zhao Qingshan took samples and analyzed them in the laboratory of the trial production workshop, and shared his test data and research conclusions at the first time: "The test data show that the effect of chromium in delaying the bainite phase transition is much greater than that of delaying the pearlite phase transition, and the 'nose tip' with the largest pearlite transformation speed does not move to the right obviously, while the 'nose tip' with the largest bainite transformation speed moves significantly to the right." When the content of chromium and carbon is high, the bainite transition velocity decreases dramatically, the CCT curve shifts significantly to the right, and the position also decreases dramatically, so that there is no bainite transition zone on the general CCT curve. Reanalysis of chromium-forming cementite, which is easy to solidify, can also delay the pearlite transition in austenite......"

"The comprehensive conclusion is that chromium is 0.50~0.60%, and yes, this is the result of my phased research. Of course, no single alloying element can play a role alone, Liang Gong, Zhang Gong, Liu Gong, I need your data, what is the situation at hand?"

Zhang Tongqiao was quite surprised and said: "Xiao Zhao, the experimental methods, experimental instruments, and experimental materials we use are exactly the same, but why is your efficiency so high? I have read your series of test data, you have made a total of ten furnaces of test steel, and the number of test samples is the same as ours, but we have made ten furnaces of waste nine furnaces, and you have hardly wasted any furnace of steel, and every furnace of test steel you have made have obtained ideal test results." The results of your series of experiments are related to each other, just like proving a math problem, your proof process is too rigorous, and there are no loopholes at all! This is a breakthrough in common sense, either you are too wise, or you are too lucky. ”

"There's a little bit of luck, there's a little bit of wisdom, anyway, the test data is like that, respect the science, respect the facts. Zhang Gong, let me see your data...... Hey, the test data of your furnace is quite strange, isn't it?"
