my scientific age

Chapter 167 Million-ton annual output!
The completion of the comprehensive science examination means that the joint entrance examination has come to an end. After lunch, there is a two-and-a-half-hour break at noon. All students use this time to get busy with their final review.

In a flash, two hours passed, and the last English test of the joint entrance exam came.

Yu Hua walked into the exam room lightly and waited for the exam.

The students around are eager to take the English test, which is one of the few subjects they are good at.

During the period of the Republic of China, English was the subject that attracted the most attention. Your math scores can be poor, your comprehensive subjects can be poor, and even Chinese can be poor, but English can't be poor.

No way, most of the school textbooks are foreign English original textbooks. As a student, if you don't know English, it can be said that you can't do anything.

A student who can speak English and a student who does not know English are treated by a huge disparity in society.

You know, this is the era of the Republic of China where the illiteracy rate is as high as 80%, and the ability to read and write, addition, subtraction, multiplication and division can be called talents.

If you have a fluent and standard English, it means 'the elite of the elite', which is the real upper class.

Students like Yu Hua who have mastered English, Japanese, and German are extremely rare. As long as Yu Hua opens his mouth, he can immediately enter the government department and get a very lucrative translation job.

After all the candidates entered the room, two acquaintances, Hu An and He Wanrong, entered the examination room, explained the discipline according to the procedure, and distributed the test papers. Soon, as the bell rang, the English test officially began.

There was a sound of writing in the classroom. All the candidates were nervous to answer the questions. Yu Hua silently wrote and wrote.

Gone are the days of relaxation when exams are over, and the days that follow are extremely busy.

Regarding the work cycle table after the joint entrance examination, Yu Hua has already formulated it.

Time passed slowly, and at 04:30 in the afternoon, when the bell rang, which symbolized the end of the English test, the very important Peking entrance examination for more than 1000 high school students in Peking City came to an end.

Exam results will be released to the public after five days.

After the end of the joint entrance examination, all the reference students have relaxed, no matter what the process is, now is the time to rest.

According to the regulations, everyone can take a day off to relieve the fatigue caused by high-intensity study.

Outside the campus, a team of students' parents and reporters from various newspapers in Peiping was surging. Everyone was looking forward to it. A pair of eyes full of anticipation turned to the inside of the school. The Chinese parents' wish for their son to become a dragon has not changed even after a hundred years.

Among the crowd, stood a middle-aged man wearing glasses, with two young men standing on the left and right sides, his eyes were sharp, revealing a hint of vigilance.

The middle-aged man had a smile on his face, his eyes were bright, and he was wearing a light gray robe, exuding an elegant and easy-going temperament, completely different from the excited parents around him.

Not long after, when a tidal wave of reference students appeared, the school gate was in a boiling state. Parents kept calling out the names of the students, and reporters from newspapers in Peiping pressed the shutters of their cameras to take pictures of the students leaving the exam room for the Peking Joint Examination.

At the entrance of the teaching building of Chongde Middle School, two figures walked towards the school entrance unhurriedly.

Lin Wan held the technical feasibility report handwritten by Yu Hua and read it as she walked, her face full of concentration and seriousness, and her eyes read the content of the report very carefully.

The entire technical feasibility report mainly focuses on the technical principle of the seven-tower device, as well as the difference and development level of sulfuric acid production processes at home and abroad.

The United States mainly adopts the contact production process, and the sulfuric acid industry is highly developed. The annual output of sulfuric acid announced in 1936 was about 450 million tons, the annual output of sulfuric acid in Germany reached 200 million tons, and the annual output of sulfuric acid in Japan was about 220 million tons.

These data are all released by various countries. In fact, the actual output is about 10% higher.

Lin Wan looked at the development level and annual output of the sulfuric acid industry in various countries given in this technical feasibility report, and was shocked. How big is the gap between those industrial powerhouses.

Abroad, reaching the million-ton level!

On the other hand, in China, since 1911 to the present, the annual output of sulfuric acid in China has been about 6 tons, which has not yet exceeded the [-]-ton mark. Tons of wandering.

"Theoretical design, design drawings, manufacturing parts, assembling prototypes for production testing, and finalizing the final shape. This is the general R&D process of the entire seven-tower device. Technically speaking, the research and development of the seven-tower device is not difficult. The main difficulty lies in the processing and manufacturing. Parts, I'm going to solve this myself, it's almost at the gate of the school, how is it?" Yu Hua stood beside him and slowly explained the general R&D process and technical situation of the seven-tower device.

Machining and manufacturing parts. ——This is the most difficult link in the entire seven-tower project research and development process. The domestic manufacturing level is extremely backward, and it is impossible to manufacture reaction towers that meet the design standards.

Regarding this problem, Yu Hua, who is not doing his job properly, is ready to do it himself and have enough food and clothing.

Yes, there is no high school student like him in the whole world, regardless of whether he is doing his job properly.

No one knows better than Yu Hua.

Lin Wan put away the technical feasibility report with a complicated expression: "I've read it."

"How do you feel?" Yu Hua asked calmly.

"It's very shocking. The intuitive data comparison makes me understand how big the gap is between China and Japan. The annual output of sulfuric acid alone is 36 times as large, and the annual output of sulfuric acid in the United States is double that of Japan." Chen was filled with emotion.

The gap is really too big.

This kind of disparity described purely by numbers makes people feel a sense of despair in their hearts, and they can't help but ask - how should China resist the aggression from Japan?

What Lin Wan didn't know was that, according to history, after the defeat of the Battle of Songhu, the Nationalist government lost the coastal industrial area, and the national industrial system capacity would drop by 90%, causing the already weak basic industries to suffer a devastating blow, and finally the situation after the war ended. , Japan's annual production of weapons and equipment far exceeds the sum of China's eight-year weapons and equipment production.

"The advantages of the seven-tower device technology are that the technology is simple, the equipment cost is low, the production management is easy, and it is not afraid of enemy bombing. In the wartime environment, sulfuric acid plants based on the seven-tower device can be manufactured in large quantities. As long as this technology is successfully mastered, With systematic centralized production, under the condition of ensuring sufficient raw materials, the production of sulfuric acid at the level of millions of tons can be achieved in a short period of time."

Getting closer and closer to the school gate, Yu Hua elaborated on the advantages and importance of the seven-tower device: "Of course, the core of the seven-tower device is to process parts."

Based on the enhanced version of the seven-tower device in the 50s of the Soviet Union, it is almost the pinnacle of the tower method, with simple technology and extremely low equipment cost. Through industrial crowd tactics, large-scale sulfuric acid production can be realized in a short period of time.

The annual output of a single piece of equipment is 8000 tons, the annual output of ten pieces of equipment is 8 tons, and the annual output of one hundred pieces of equipment is 80 tons. Only 130 pieces of equipment are needed to reach an annual output of 104 million tons.

Moreover, in the production process of the seven-tower device, by-products such as synthetic ammonia and nitric acid, which are extremely important in the field of fertilizers, will also be produced.

Of course, the above premise needs to meet a considerable level of component manufacturing and sufficient raw materials.

The raw material sulfur, according to Yu Hua's qualified geographical knowledge records, the entire Chinese territory except the Shanghai stock market, there are sulfur ore distribution in all regions of the country.

"So, we must master the processing technology and equipment of the parts, right?" Lin Wan heard Yu Hua's description of the million-ton annual output, her heart thumped, and she suppressed her inner desire. After thinking about it carefully, she quickly understood Yu Hua. given emphasis.

Talking to a smart person is easy, Yu Hua nodded and blinked at Lin Wan: "Yes, I am going to set up a seven-tower installation technology research and development team, and I sincerely invite Jinyu to join. What do you think?"

There was a hint of fun in the words.

Find someone to borrow money, and let others contribute, the only one in the world.

"I promise."

When Lin Wan heard this, she was startled for a moment, and readily agreed, "Is there anyone else in the technology research and development team?"

"Yes, two people, classmates from school, you should know each other." Yu Hua nodded: "There are four people in total, many people are powerful, and it is too difficult for me to develop technology alone."

Lin Wan was curious: "Who is there?"

"Tomorrow you will know." Yu Hua smiled slightly and did not answer the question.

Seeing Yu Hua's mysterious appearance, Lin Wan was helpless and came to the crowded school gate, trying to avoid the crowd, when suddenly, a familiar voice came over: "Miss."

Miss?

Hearing this voice, Lin Wan froze for a moment, somewhat incredulous, turned around, and saw a middle-aged man in a light gray robe walking over.

Looking at the middle-aged man's face, Lin Wan's pupils shrank suddenly, her heartbeat quickened, and she was a little sluggish.

This man is not her father, but...

Comrade Professor!
