It is very expensive to run a university, Huaxia University of Science and Technology does not charge tuition, and there is a meal allowance of 30 catties of grain every month.

The salaries of the teaching staff are not low, and they have to be given a house, and those who don't have a wife have to pay a wife.

If it is calculated, it will cost at least 100,000 taels of silver a year to ensure the normal operation and scientific research of Huaxia Institute of Technology.

The only way to generate income is to get a share of the patent fee after the research results are obtained.

Discussions are also underway to prepare an open university research project that would allow the university to be commissioned by companies or factories to solve certain problems in order to earn some funding.

Even so, universities will need government funding for a long time to come.

Unless there is a large number of students, tuition fees are charged, and the school is used as a diploma factory.

However, this is a matter after the popularization of education, and it is not suitable for elite education in the initial stage.

However, these investments are worth it anyway, and the cultivation of talents is also a quantitative change to a qualitative change.

The value that can be created by 10,000 talents is not ten times that of 1,000 talents, but 100 times or even 10,000 times!

Yan Zheng returned to the Red Room and immediately took out the article that had already been written - "A Hundred Years Plan, Education-oriented".

He plans to add another thousand primary schools, a hundred secondary schools, and two universities in the next five years.

In addition, the Ryukyus, Penghu, and Luzon have also been included in the areas where primary education is popularized, and primary schools are being built in these places.

He even planned the construction of a nursery school and prepared to standardize the nursery school.

At present, the baby boom in Eastern Qin is still breaking out, and many villages have found five or six old wives in accordance with the advice of the state government to make a yard in the barn as a nursery.

This kind of nursery school built by the villagers is not only not standardized, but also has great hidden dangers.

As a father, Yan Zheng couldn't tolerate it, but after considering the actual situation, he still chose to only pilot and promote it in urban areas.

"Oh~wave~wow...... Wow......"

After finishing his business, Yan Zheng walked to the two small cradles with a smile, and the two little ones opened their eyes wide and looked at the bells on the cradles curiously.

The elder brother is a quarter of an hour older than the younger brother, and he is named Yan Ruying, who looks very much like Lan Ya, with only a pair of eyes and a nose like Yan Zheng.

The younger brother is thinner than the elder brother, and his name is Yan Ruqing, but he looks the same as Yan Zheng, but his eyes are inherited from Kaori, and he has a pair of big apricot eyes.

The two mothers also waited aside, looking at the father and son with a gentle smile.

Yan Zheng stretched out his hand to pick up Ruying, the little guy blinked his eyes, and spit out a bubble, which made Yan Zheng laugh.

It wasn't until he was held in his arms that he struggled, and he cried after struggling.

The younger brother stayed in the cradle, as if he understood his brother's grievances, and cried along.

Yan Zheng smiled even more happily, and the fatigue of the day was swept away.

After that, he is no longer willing to talk about too many ideals, which is the selfishness in his heart.

He handed Ruying to Lan Ya, looked at Kaori and said, "Send a letter to your father and tell him that you have given birth to an heir!"

Kaori Shimazu was stunned for a moment, then overjoyed, and hurriedly bowed and said, "More...... Thank you! ”

She mentioned before that she wanted to give good news to her mother's family, but Yan Zheng never agreed.

…………

A few days later, Huaxia Institute of Technology began to officially start classes.

Students from all faculties have also received new textbooks, which are more advanced than they were in secondary school.

The chemistry students even have a booklet about the synthesis of various strange substances.

Yang Ziwen: On the first day of class, under the guidance of the tutor, they read the contents of this booklet.

Their tutor is Wang Erhu, both of whom are from Dagang Township, and they were taken care of when they were enrolled.

To Yang Ziwen's great disappointment, the knowledge of chemistry in college seemed boring.

It wasn't until five days later that Wang Erhu took them to an outdoor test area.

They were all required to wear protective clothing made of leather and goggles.

Under the operation of Wang Erhu and several other teachers, they saw the ongoing sulfuric acid production experiment.

The method used is the "lead chamber method", in which a "lead chamber" with a length of about one meter and a width of about one meter is placed on the ground.

Wang Erhu pointed to the lead room and said, "Do you know why you use lead to make sulfuric acid?"

The students shook their heads.

"If you don't know, take out the notebook, let me tell you, lead is a substance, as long as it reacts with dilute sulfuric acid, it will form a thin film, which has very good corrosion resistance to dilute sulfuric acid, and the sulfuric acid we can make, the initial concentration should be about 40%! If lead is not used, the rest of the material will not be passivated. ”

"Of course, if the concentration goes up, the same goes for steel. However, steel is not as easy to process as lead, and lead is soft, except for the disadvantage of too high density, in the sulfuric acid industry, it is almost a panacea! Lead can be used for pipes, lead can be used for reactions, and lead can be used for everything except the combustion chamber. So at present, the lead chamber method produces sulfuric acid, and there is almost no problem! ”

"The biggest difficulty that bothers us is how to get higher purity sulfuric acid, which requires us to continuously optimize, we can use the contact type, but the pollution is too great, and the harm to the human body is too great, so it was stopped by the king. At present, as long as the contact process can be optimized, our 'lead chamber method' can be finalized and the factory can be built! ”

Wang Erhu smiled and introduced them one by one, after having a large number of students, they have more coolies in their hands, and they can study in several directions at the same time.

The students were stunned, remembering their instructor's words while looking curiously at the device in front of them.

Wang Erhu also introduced the "boiling furnace", "incinerator", and the circular cylinder furnace that can burn sulfur and increase the concentration of sulfur dioxide.

Don't look at the sulfuric acid industry for almost two or three years, in fact, it has been improving, if it weren't for the high concentration of sulfuric acid, there wouldn't be so much at all.

However, in order to sulfonate the reaction, the concentration must be increased.

And now they are tackling the concentrator unit, as long as they find a suitable way to increase the concentration of sulfur dioxide gas and purify it.

Because the whole principle of preparation is to produce sulfur dioxide gas through the combustion of sulfur or pyrite, and then oxidize to sulfur trioxide, and then through the absorption chamber, sulfur trioxide and water react violently to obtain sulfuric acid.

It sounds super simple, but it actually makes people want to scold their mother.

However, the instructors of the entire chemistry department understood that it was only a matter of time before they conquered the sulfuric acid industry, because they had already figured out several directions and were waiting to complete several sets of control experiments.

Yang Ziwen looked at the entire orderly device, and the fire in his heart was faintly burning again.

Wearing protective clothing and goggles, he stood in front of the device in an orderly manner, and through certain operations, he obediently produced the desired substance.

It's a great feeling, like a spell that turns a stone into gold.

…………

On the other side, in the building of the Department of Physics.

Wang Sen also began a hard research career under the leadership of his mentor.

His mentor's name is Deng Yong, and his teacher's name is Mo Ya.

At the first meeting, they saw the big-bellied teacher, and they were all kinds of envy and jealousy for a while.

The project they did was called 'differential miniaturization', which was to continuously optimize the differential using mechanics and the involute principle.

When he first saw the principle of the differential, Wang Sen almost dropped his jaw, thinking that the person who could invent this thing was definitely a genius.

As a result, the tutor Deng Yong told him that the principle of this differential was figured out by the king, as if he and the rest of the teachers presided over it together.

This made them, the students of the physics department, fall to their knees, feeling that they would not be able to catch up with the knowledge that the king had mastered in several lifetimes.

"Everyone also understands that the number of gears, diameter ratio, and arm length of the differential will affect its work, in fact, if you insist on saying it, our job is to do a force analysis for the differential, and the force analysis is successful, and it will be!"

Deng Yong usually talks to the students, gesturing a differential with his hand. This thing is an artifact in horse-drawn carriages, trains, cranes, and a lot of machines to turn! Especially in machine tools, with differentials, the machine tools originally made by the soil method will usher in another wave of qualitative changes.

Their physics department is also the most complicated, and they can't help but study mechanics, optics, air buoyancy, shell structure, in short, they can get a foot in all walks of life.

"Deng Yong, it's time to eat!" Just as Deng Yong was talking energetically, Mo Ya poked his head out of the door and said.

Deng Yong smiled helplessly, so he had to end the dragging.

He was young and ignorant, and after being tricked into repairing the chimney a few times, he finally caught fire with this aboriginal female classmate, and coincidentally, he was caught by his parents for the first time.

They didn't say anything, but they were happy. As a result, as soon as he returned home, he was almost killed by his own father.

He had no choice but to get married early, although it was a bit of a sparse lake, but it was also happy.

It's just a little bit of a way to affect the work.
