The next day, Cheng Nuo bought a bunch of gifts and prepared to take them to Tianjin as a guest.

With the sound of squeaky wheels, Li Laosan, who was riding a bicycle, turned around and said with a smile: "Sir, you buy so many things, don't you sink it when you take the train, if you want to change it to Lao Li and me, it must be after taking the car to Tianjin, and then take the money to buy it, isn't it?" ”

Cheng Nuo patted the pastry gift box at his feet and said with a smile: "Some processes can't be omitted, just like this gift, will Mr. Fan lack this thing, there is naturally no shortage of family wealth, so let's not so much give a gift, but a heart." ”

Li Laosan withdrew his gaze, frowned and thought bitterly: "Just like what Mr. Guo said, send chicken feathers for thousands of miles, and the courtesy is light...... Polite, anyway, sir, you know what I mean. ”

"Haha, what kind of chicken feathers are that, that's goose feathers," Cheng Nuo smiled and explained: "I have to give chicken feathers, it's not impossible, but it's not a gift, but a chicken feather letter." ”

"It's a good thing I didn't let the dog come with me, otherwise the father would have been laughed at by his son to death." Li Laosan's face turned red, and he relied on his strong psychological quality to hold on: "But sir, such a good business, why do we have to find someone to help, aren't we sending money out for nothing?" ”

Cheng Nuo smiled and shook his head: "Because fighting alone is not our style, especially in this turbulent world, one more friend means one less potential enemy, and the harvest is far more than just the money on the surface." ”

Curious, Li Laosan originally wanted to continue to ask, but when the words came to his lips, he suddenly thought of Cheng Nuo's words, and it was estimated that it should be at the point where he couldn't understand, and it was quite brain-consuming to understand, so it was better not to ask.

"That kid in my family is not young anymore, go back and call him over to Mr. You as a scholar, let him study by your side, don't be like me, I don't know anything for most of my life." Li Laosan held the handlebar with one hand and said while wiping the sweat on his head.

Cheng Nuo just smiled at this, and did not agree or object.

Close your eyes and recuperate, let the hustle and bustle of the street pass by your ears, not only do you not feel anxious, but you have a kind of truth in the world.

However, thinking that Li Laosan has asked this question, there must be many comrades in the Academy of Sciences who have the same idea.

If these people only reserve their opinions, it is fine, but if they drill the horns of the bull and go down the wrong path in the future, it will be a great loss for everyone.

Cheng Nuo simply untied this knot before leaving for Tianjin.

"Some people say that we have an advanced alkali and acid production process, why can't we just run a separate factory to make money like mastering the match technology before, and all the profits can be used on ourselves, continue scientific research, and form a sustainable cycle of production, education and research, isn't it beautiful?"

Sure enough, some comrades nodded unconsciously, obviously agreeing with this point of view.

Cheng Nuo did not rush to refute this, got down from the rostrum and walked to the middle of the crowd, and said with a smile: "British classical economists have a book on economics that took ten years of painstaking efforts, I don't know if you have heard of it, and if so, are there any comrades who are willing to stand up and talk about it." ”

As soon as he finished speaking, a young man with a capable figure stood up: "The title of the book is "A Study of the Nature and Causes of National Wealth", referred to as "The Wealth of Nations", which mainly talks about the nature and source of national wealth. ”

Cheng Nuo raised his eyebrows, very satisfied with this answer: "Concise and to the point, the summary is very good, by the way, what is your name?" ”

The young man didn't expect the dean to like this answer very much, and said incoherently excitedly: "Hello dean, I'm ...... My name is Fang Xianting, I happened to see this book in a bookstore, and I read it several times before I knew it by heart, if you asked something else, I might not know. ”

"It's okay, a book like this, it's enough for some people to read this book for the rest of their lives." Cheng Nuo raised his hand and pressed down, asked the other party to sit down first, and asked, "Fang Xianting, good name, but we should be meeting for the first time, you don't seem to be from our Academy of Sciences, right?" ”

Fang Xianting, who had been sitting down, heard this, his buttocks seemed to be yellow, and he immediately stood up again, blushing: "Dean, I'm sorry, I'm just a worker from Shanghai who came to help, and I happened to pass by the auditorium and heard that you were lecturing, so I couldn't help but come in and disturb you, I'll go out." ”

After saying this, Fang Xianting really packed up his pen and paper, hooked his head and was about to leave.

Although this person has not yet become a big economist at the moment, since they have all taken the initiative to send it to the door, where will they let it go.

"There is a lack of a clerk in the reference room, if Comrade Fang doesn't mind, you can work here first to get used to it, what do you think?"

Fang Xianting was about to walk to the last row, and when he heard this, his head immediately raised and his eyes lit up: "Can I really do it?" ”

Cheng Nuo rubbed his nose and said with a smile: "Why not?" ”

Fang Xianting, an apprentice, is also a legendary figure, completing all the courses of the University of Wisconsin's preparatory and business school economics departments in three years, and in the four years after obtaining his bachelor's degree, he received a master's degree and a doctorate.

After returning to China, he actively devoted himself to national construction, and became one of the most fruitful people in the study of Western economics in China at that time, and was known as the four great economists of the Republic of China together with Ma Yinchu and others.

The reason why Cheng Nuo kept him was that in addition to cherishing his talents, he also wanted to find a deputy for Jiang Jiang Zuo.

After all, I had promised others a long time ago that I would arrange more assistants for him.

Returning to the topic, Cheng Nuo stood on the podium again, looked around the entire auditorium, and said seriously: "Comrade Fang's theory of national wealth, we will have a chance to talk about it in the future, what I want to talk about today is Adam Smith's monarch theory!" ”

As soon as these words came out, except for Fang Xianting, everyone in the hall was shocked.

You must know that not long after Zhang Xun's restoration, and now he wants to publicly say what monarchy theory is, it really has to make people think about it.

However, Cheng Nuo on the stage did not give everyone a chance to continue to think more, and after seeing the atmosphere in the auditorium being mobilized, he copied the original excerpt of a passage from "The Wealth of Nations" on the blackboard at the back.

"It is the duty of the monarch first and foremost to protect the security of his own society from the atrocities and aggressions of other independent societies."

"The second duty of the sovereign, to protect the people from the oppression or oppression of any part of society by others, is to establish an administration of justice."

"The third duty of the monarch is to establish and maintain certain public institutions and public works."

Throwing the chalk back on the table, Cheng Nuo patted the dust on his hands and slowly introduced: "Considering that Adam Smith's Britain is a constitutional monarchy, we can directly understand it as a national government, which means that the government should play three important functions in social and economic life.

That is, the three functions of ensuring national security, maintaining social and economic order, and providing necessary infrastructure, the most important of which is to protect the country's commercial interests from infringement.

Commonly known as - the Night Watch. ”

In fact, since the Second World Industrial Revolution, Western countries have gradually strengthened their intervention in the leading industries that are related to the lifeblood of the national economy, and have launched incentives, protection or industrial development plans for emerging industries such as electrical, heavy chemicals, and automobiles.

The most obvious of these is that the French state-owned economy accounts for more than 70% of the total national economy.

Even our "good neighbor" Japan, where the rise of heavy industry, is basically led by the Japanese government, not only government-run and government-business joint ventures rely on government investment, but also private enterprises have sought policy support and financial support from the government.

Seeing that the people in the audience were almost digested, Cheng Nuo said slowly: "Taking the alkali in the acid-alkali industry as an example, we now use more than 30,000 tons of alkali every year, of which 6/7 are foreign alkalis, and the heavy chemical industry is a typical capital-intensive and technology-intensive industry, which is inseparable from the intervention and support of the state." ”

After saying this, Cheng Nuo left the venue directly, leaving everyone at the venue to continue the discussion.

As for the specific details of the cooperation, it is not appropriate to say them in public.

In the remaining days, after Cheng Nuo submitted a visit post to Fan Xudong, he did not come directly, but first started a chemical experiment in the office of the aviation school.

On the one hand, Fan Xudong had just prepared a soda plant with the Salt Affairs Department of the Ministry of Finance, and he needed to check all kinds of work, and he lacked skills.

On the other hand, Cheng Nuo also has the heart to personally improve the alkali formula, and the technology is more real than any gift.

In fact, at that time, there were two industrial alkali production methods in the world: one was the Rubran method, which was simple in technology but poor in quality, and the other was the Solvay method, which was complex in technology, but good in product quality and low in cost.

This alkali production method first reacts with ammonia, water and carbon dioxide to produce ammonium bicarbonate, and then reacts with sodium chloride to obtain sodium bicarbonate and ammonium chloride, and sodium bicarbonate is heated and decomposed to obtain soda (sodium carbonate).

The Solvay method, also commonly known as ammonia alkali method, is characterized by continuous production, and all the machinery and equipment in the entire process are connected to form a complete system. There are seven main parts to the whole process, and production can only be carried out if all seven parts are functioning properly.

If one part fails, the balance gets out of control, and production is severely affected and even an accident occurs. Therefore, the adoption of such a process requires a high level of skill and careful management.

China did not want to use this method to change the alkali industry, and even did not hesitate to spend tens of thousands of dollars to buy the formula.

But after getting the formula, I found that this thing is not a panacea, the demand for salt is too great, and it is the main raw material for alkali production.

The ratio of soda ash to waste calcium chloride is 1:1, that is, for every ton of soda ash produced, there is also a ton of waste liquid calcium chloride produced.

The characteristics of China's salt management are: the price of salt is as cheap as sand, and the salt tax is surprisingly high. Taking Tanggu as an example, sea salt is only 2 jiao per quintal, but the salt tax is 3 yuan per quintal, which is expensive and ordinary factories cannot afford it.

At present, the only way to solve this problem is to move out the Hou's alkali production method in advance.

Cheng Nuo hurriedly arranged for Li Laosan to buy or customize chemical utensils, and he went to buy some chemical preparations.

Speaking of which, it was precisely because of the invitation of Fan Xudong that Mr. Hou Debang resolutely returned from studying in the United States and joined Yongli Alkali Company, and invented Hou's alkali making method after several twists and turns.

Now that Hou Debang is still studying in the United States, Cheng Nuo already has an idea in this regard and implemented it, and he still feels a little guilty in his heart.

However, the matter is urgent, and it is used in advance to develop the domestic chemical industry, and from a macro point of view, the advantages outweigh the disadvantages.

As for the personal aspect, it was retained as Cheng Nuo's follow-up compensation.

Moreover, when the Hou's alkali production method was first created, it caught up with Japan's invasion and occupation of Indochina, and also blocked the port into Sichuan, and the construction of Yongli alkali factory was also forced to stop, so Hou's alkali production method slept in the safe for six years.

For so long, it is enough for the domestic industrial strength to reach several new levels.

As a junior high school chemistry knowledge, this thing is naturally difficult for Cheng Nuo.

“nh3+nacl+ahh4cl”

After transcribing the chemical equations, he began to explore the process of making alkali.

The salt-containing mother liquor is sent to the carbonization tower with ammonia, carbon dioxide is introduced to produce sodium bicarbonate crystals, the mother liquor is cooled after filtration, ammonium chloride is precipitated by adding salt, and the mother liquor is sent to the carbonization tower by absorbing hydrogen again, so that the continuous cycle operation obtains two products of soda ash and ammonium chloride.

Carbon dioxide Chengnuo has also planned to build an ammonia plant at the same time, which can successfully utilize the carbon dioxide that was originally exhaust gas, which can greatly reduce production costs.

It not only eliminates the trouble of calcium chloride in the remaining waste liquid of Solvay method, but also obtains ammonium chloride, an agricultural fertilizer product.

In line with Chengnuo's original intention of developing agriculture, agriculture and agriculture.

You must know that the fertilizer in this era is generally based on rium sulfate, although this thing can significantly increase fertilizer and increase food production, but in fact, it is particularly harmful to the environment, increasing soil acidity, destroying soil aggregate structure, prone to pests and diseases, etc., in the long run, it will do more harm than good.

No matter from which point of view, Hou's alkali making method is far superior to Solvay's method, and it can also combine the acid and alkali chemical industry with a perfect match.

Looking at the alkaline noodles of Baihuahua, Li Laosan was surprised: "Sir, do you know the Tao, why do you use a little bit of this, use a little of that, and actually make alkaline noodles, you are too powerful." ”

Cheng Nuo had a hint of pride: "Do you want to learn?" ”

Li Laosan nodded hurriedly: "I want to learn, I want to learn, I want to learn." ”

Cheng Nuo went up and threw the copied equation over, and said with a smile: "When you can read this thing, you will also learn it." ”

Originally, Cheng Nuo just wanted to use this method to let Li Laosan learn more about other knowledge, but he didn't expect that because he couldn't understand it, he would lead him crookedly.

"Sir, is this the talisman you cast? Is it really okay to pass it on to me? ”

Cheng Nuo was immediately so angry that he directly held his head, took the chemical equation over, and waved his hand to let the other party leave: "Stay where it is cool." ”

"Hey, you're busy, sir!"

"Come back, what were you doing here?"

"Oh, I almost forgot, that Mr. Fan Xudong Fan asked someone to come over, saying that he would come to visit Mr. in person in the afternoon."
