There are only two days left before the arrival of the twenty-fifth week of 1937.
While Princeton on the other side of the ocean was busy arranging the publication of the latest article, here, the editorial department of the Journal of Tsinghua University also received three heavyweight papers co-signed by Zhuang Qianding and Yu Hua.
"Qingyue, this is a submission from Professor Zhuang of the Department of Mechanical Engineering. You can review it here and hand it in if there is no problem. It will be just in time for the latest issue of the journal on July 1st."
"Yes, Director." In the editorial office, Liao Yaquan, who has joined as the preliminary editor, is wearing a skirt that flatters the female figure and light makeup, exuding a gentle temperament of the Jiangnan water town.
As a top student with experience studying abroad at Kyoto University, Liao Yaquan is more than qualified to serve as the preliminary editor of the Tsinghua editorial department. After all, this kind of academic editor is basically a voluntary and free labor force.
During the initial interview, Liao Yaquan encountered no obstacles and easily entered the editorial office of Tsinghua Journal.
Now, her name is not Liao Yaquan, her surname is Ye, and her given name is Qingyue, which means the bright moon in the sky is cold, which is quite artistic.
Ye Qingyue, no, Liao Yaquan poured a cup of warm boiled water, suppressed the hunger in his belly, opened the three submitted papers on the table, and reviewed them according to the standards.
Since joining the editorial department of Tsinghua University, the situation that Liao Yaquan has been most uncomfortable with is the Tsinghua meals that are seriously lacking in protein and fat. Every day he has either multi-grain steamed buns or steamed buns, and occasionally some strange steamed buns. His quality of life has plummeted.
Really, Liao Yaquan would never eat such food eaten by low-class people if it were not for the mission requirement.
The problem is that it has been more than ten days since he joined the company, and Liao Yaquan has made basically no progress. There is no way to find out about Zhang San’s mailing address and related information.
The Tsinghua Journal Editorial Department maintains an absurdly high level of confidentiality regarding scholar Zhang San’s information.
According to Liao Yaquan's guess, Tsinghua professors such as Wen Yiduo, Chen Yinke and Ye Qisun must know information about Zhang San, but it is simply unrealistic to learn Zhang San's whereabouts from these people.
The day after tomorrow is July, what should I do?
July is the deadline given by His Excellency Madoka Doi. If she fails to make any breakthrough in finding Zhang San before then, there will only be one consequence waiting for her, which is to be sent to the freshman salon.
Liao Yaquan frowned slightly when he thought of this. The information about the freshman salon subconsciously appeared in his mind. His heart trembled slightly. He took a deep breath and forced himself to stay calm and complete the current work of disguising his identity.
"Zhuang Qianding, Yu Hua, a method of deep hole processing based on lathes." Liao Yaquan looked at the first mechanical engineering paper. After reviewing the author information and title, his eyebrows wrinkled slightly.
Deep hole processing based on lathe?
How can this be?
Liao Yaquan was very surprised and surprised. Although she was an agent and did not have a deep understanding of science and technology, she did receive a complete higher education and had basic literacy and knowledge in technology.
Mechanical processing equipment such as lathes are generally used for turning processing in China. How can it be used for deep hole processing?
The most important thing is that it was created by the Chinese.
Can the Chinese create this method?
The answer is obvious.
Liao Yaquan felt that his knowledge had been greatly impacted. With a hint of contempt and curiosity in his eyes, he looked at the text of the article and read it carefully.
One minute.
Two minutes.
five minutes.
ten minutes.
During this short period of time, Liao Yaquan almost forgot his identity, immersed himself in the field of mechanical engineering, and experienced the crystallization of knowledge that condensed the wisdom of Professors Yu Hua and Zhuang Qianding.
As his eyes moved to the concluding paragraph on the last page of the paper, Liao Yaquan sat on the chair without saying a word after reading it. The contempt and disdain in his heart disappeared and were replaced by shock and amazement.
From a mechanical engineering perspective alone, the deep hole processing method based on lathes in the article is completely feasible.
Not only is it feasible, but the processing efficiency and accuracy are not low. Although Liao Yaquan is not clear about the efficiency and level of deep hole processing of gun barrels in the domestic manufacturing industry, she has a vague feeling that this method is only weaker than the domestic front-line.
A groundbreaking concept that maximizes the role of lathes instead of specialized turning.
Liao Yaquan was full of amazement. This academic achievement, signed by Professor Zhuang Qianding and classmate Yu Hua, has extremely high military application value.
Deep hole processing in this era is, in a popular sense, gun barrel drilling.
From the perspective of the initial review editor, this article has a standard structure and extremely high quality content.
"Damn it, why is this method of increasing the potential of China's military industry born at this juncture?" Liao Yaquan came back to his senses, looked at the paper in his hand, and couldn't help but curse in his heart.
This method of using lathes for deep hole processing allows a considerable number of lathe equipment to carry out deep hole processing, effectively increasing the output of drilled barrels, which is of great use.
What should I do?
Should I destroy the paper or review and submit it?
Liao Yaquan's breathing was slightly rapid. This paper was good for China but bad for the motherland. She could not tolerate the publication of this paper.
At this moment, the editorial director in charge of the preliminary review arrived again and asked Liao Yaquan: "Qingyue, how was the review? Professor Zhuang is an outstanding mechanical engineering expert in our school. His paper is very important and cannot be delayed.
"
Special treatment is available everywhere. For the Tsinghua Journal, since the quality of articles submitted by outsiders is generally low and substandard, special attention is paid to submissions from within the school.
Manuscripts by professors at the department head level like Zhuang Qianding are paid special attention to by the person in charge of the preliminary review department.
Hearing the words from the preliminary editorial director, Liao Yaquan's expression suddenly froze. He wanted to speak, but didn't know what to say.
This paper written by Professor Zhuang Qianding is very standard, with basically no nitpicks or mistakes.
"Forget it, give me the article, there are still 2 days left, we can't delay." Seeing Liao Yaquan's appearance, the editorial director of the preliminary review immediately knew that nothing good had come out of the review. He shook his head, feeling a little disappointed, and then took it from the table.
Take three papers.
He originally planned to train this talented editor who studied abroad, but unfortunately, his performance today was not very good.
"..." Liao Yaquan stared at all this blankly. The disappointment in the eyes of the preliminary editorial director was like the tip of a knife piercing her heart.
The most important thing is that the other party also took away three papers!
The first paper can improve the production of drilled gun barrels, but what about the second and third papers?
"We can't go on like this, we must do something." Liao Yaquan clenched his right hand tightly, suppressing the emotions in his heart, thinking calmly, and made a decision.
…
June 30, the last day of June, today is the time when National Tsinghua University holds its final exams. There is a serious atmosphere in Tsinghua Campus, and all students are preparing for the final exams.
Of course, except Yu Hua.
As the only recommended student in Tsinghua who reported to school in advance, Yu Hua enjoyed the privilege of being exempted from taking the final exam. The reason was simple. Yu Hua had only been in school for thirty days, so it was unfair for him to take the final exam.
In the blink of an eye, one month has passed from June 1st to now.
Tsinghua University Nuclear Physics Laboratory, second floor office.
As the assistant of Professor Zhao Zhongyao, Yu Hua enjoys the treatment of an independent office. The area is small, about nine square meters, and it is more independent and free.
Since accepting the offer from the Nuclear Physics Laboratory, Yu Hua has not moved out of the dormitory, but has basically lived in the laboratory. He just wants to say one thing now - it smells great.
An independent and quiet private environment, a minimal workload, and plenty of free time. You can take a small amount of time to go to class every day, and the rest of the time can be freely used.
Really, this kind of treatment is not very satisfying to Yu Hua.
Thanks to the objective environment of the nuclear physics laboratory and without the interruption of others, Yu Hua was focused on his early research on oxygen lance technology and was about to complete the theoretical design from a mechanical engineering perspective.
From the perspective of metallurgical engineering, as the core equipment of the oxygen top-blown converter steelmaking process, the oxygen lance plays a leading role in the converter steelmaking process, injecting high-pressure and high-purity oxygen into the converter metal molten pool at supersonic speed.
side, catalyzing internal smelting reactions and rates.
The reason why the oxygen top-blown converter steelmaking process is an order of magnitude more efficient than the open-hearth steelmaking process is oxygen.
From a mechanical engineering perspective, an oxygen lance consists of three components: a nozzle, a gun body and a gun tail.
The nozzle is the most important core of the oxygen lance. The quality of the nozzle determines the final performance of the oxygen lance, which in turn affects the smelting effect and blowing time, and ultimately affects the quality and output of the steel. This is the core difficulty in the entire oxygen lance design.
There are two main problems Yu Hua faces now, one is the design of the nozzle, and the other is the material of the nozzle.
As an oxygen lance nozzle, it must meet the most basic conditions of use - withstand the transmission and pressure of supersonic airflow, improve oxygen utilization, have a reasonable impact area, increase the slag-forming speed of the molten pool liquid level, and have little destructive effect on the converter lining.
,increase the thermal efficiency in the furnace.
These are professional terms. In one sentence, it can be sprayed, sprayed, and heat-resistant.
In addition, it must have a long service life, at least it cannot be damaged after a few days of use.
This is a design requirement. The problem of nozzle material is easy to solve. Either use industrial grade copper or industrial grade pure silver.
Silver has the highest thermal conductivity coefficient, but is expensive, while copper has the second highest thermal conductivity coefficient and is cheap and affordable.
Considering the economic cost, Yu Hua chose the former.
Using sterling silver to make the nozzle, Yu Hua did not waste his fortune to this extent.
