The train driver in the courtyard

"Old Zhu, let's talk about this after the research and development work is completed. I know Representative Li. He is not the kind of person who cherishes his own things."

Wang Qingdian was not the kind of person who would take on too much, and Zhu Yuanrong had no other choice but to urge the researchers to speed up the development process.

As time went by, the CJ type fixed bed reaction device was manufactured.

In the laboratory, Li Aiguo carried out testing work.

Seeing that the CJ fixed bed reactor was running normally and all indicators were within the range, there was a warm cheer at the scene: "We succeeded!"

Zhu Yuanrong also came over specifically to monitor all the data of the fixed bed throughout the process.

Seeing that the temperature control remained stable, Zhu Yuanrong knew that Beijing Chemical was in luck this time.

The biggest difficulty in fixed bed reaction equipment is temperature control.

Most of the subsequent projects were undertaken by the team led by Wang Qingdian, while Li Aiguo entered a "resting" state.

I would walk around the laboratory every day, and then return to the office to write down the theories used in the CJ type fixed bed reaction device.

Most of these technologies and theories come from later generations and can inspire chemical researchers of this day.

The foundation is the basis!

The days passed by.

A week later, Li Aiguo handed the three articles he had written, namely "Non-Thermal Equilibrium Theory", "Argumentation of Multiphase Flow Coupling" and "Microscale Heat Transfer Theory", to Wang Qingdian.

Wang Qingdian finished reading the first article in ten minutes and nodded slightly: "It's quite interesting."

Wang Qingdian spent a full twenty minutes reading the second article, stroking his fingers on the manuscript paper. “This idea is quite unique and can be published as a paper.”

Wang Qingdian couldn't help but become interested in the third article. He took a look at it, exclaimed, and moved closer to the desk lamp to read it carefully.

In the light of the lamp, he looked and talked to himself.

"Currently, international research on microscale heat transfer mainly focuses on heat conduction issues. This article is rare in that it considers radiation and convection issues."

"It is said that Mr. Tian seems to have started researching this field."

Li Aiguo was shocked when he heard this.

You should know that the theory he came up with was simplified by removing details that were ahead of their time from a new discipline in later generations - micron/nanoscale heat transfer.

Under this theory, thermal conductivity at the microscale does not depend solely on the thickness of the material.

It is also related to scale effect, thermal conductivity fluctuation phenomenon, flow and heat transfer in micro-channels, flow compressibility and interface effect.

This theory may sound a bit strange, but it can solve the problems of low conductivity, high energy consumption and high equipment requirements in synthetic ammonia.

It can also improve the catalytic efficiency of iron-based catalysts.

These two technologies have always been the bottleneck of domestic synthetic ammonia technology.

Li Aiguo originally wanted to use the mature synthetic ammonia technology, but after thinking about it carefully, he found something wrong.

The complete set of synthetic ammonia technology is too complicated. It not only involves technical requirements, but also requires the participation of basic disciplines such as engineering and chemical technology.

A large-scale synthetic ammonia plant requires the participation of at least tens of thousands of technicians from various disciplines.

Li Aiguo is a man made of iron, but how many nails can he hammer?

At critical moments, we still have to rely on collective strength.

In addition, the technology of later generations may not necessarily work in this era due to the limitations of basic conditions.

So Li Aiguo thought of adding sand.

It's just that he mixed it with gold.

As long as the problem of microscale heat transfer is solved and we can find some new technologies, domestic chemical workers will naturally be able to make gradual progress and eventually find a path to synthesizing ammonia that belongs to us.

I didn’t expect that a Mr. Tian would pop up now.

Li Aiguo asked with great interest: "Which institute is Mr. Tian from? What is his full name?"

Wang Qingdian seemed a little hesitant about this question. He was silent for a moment and then uttered a name: "Professor Tian Changlin from the Thermophysics Laboratory of the University of California."

"He and I were classmates. When we were at Xiaomei's house, Mr. Tian had already started studying radiation and convection problems."

Li Aiguo was silent.

The reason why Xiaomei's family was able to develop rapidly in later generations had a lot to do with the unrest in various parts of the world, and outstanding talents all ran to his family.

Wang Qingdian seemed to think that the topic was too heavy and did not continue.

He held the article and said, "Driver Li, although this theory has no practical proof, it is indeed feasible in terms of concept. In particular, I always feel that it is related to the catalytic problem in synthetic ammonia."

There is nothing wrong with the way you feel. Keep feeling that way.

"These are just some of my crude opinions. If you have time, you can give me more advice." Li Aiguo said.

Wang Qingdian smiled and said, "We should learn together and make progress together. Come, my friend, have some tea and let's have a good discussion."

Wang Qingdian boiled two cups of tea with an alcohol lamp. While drinking the tea, the two had an in-depth discussion on "Microscale Heat Transfer Theory".

Although Li Aiguo had theories from later generations, he knew the results but not the reasons.

As a veteran in synthetic ammonia research, Wang Qingdian has many years of practical experience, but he lacks a stepping stone.

The two people's ideas combined with each other, producing sparks and lightning.

It was not until two o'clock in the morning that Wang Da Kui's voice was heard outside. Li Aiguo yawned and stood up.

"Mr. Wang, you should also take a rest. I have something else to do today, so we can't talk for long."

“good good”

Wang Qingdian also knew that this was just the beginning of a long journey and he must not be impatient.

After seeing Li Aiguo off, Wang Qingdian was still in high spirits and studied at his desk for another half an hour before returning to his room and lying on the bed.

Just lying down, he suddenly sat up again.

He turned around and ran to the desk, pulling out a thick stack of experimental data.

"I seem to have found the reason why the solid-phase production process fails repeatedly."

The dim light from inside the house shone through the broken windows, dispelling the darkness on the rugged road.

Although there is still a long dark road ahead, there is progress after all.
-
On the half-lit and half-dark road, Li Aiguo flicked on his flashlight and shone it at Wang Dagui standing opposite him: "Why, the train hasn't arrived yet? Are you going to pick up your bride so early?"

Today was supposed to be Liu Tianquan’s wedding day.

However, neither the groom Liu Tianquan nor the new bride Huang Sen has arrived in the capital yet.

This matter is about the child mentioning his mother, it’s a long story.

Last week, Li Aiguo asked a construction team to clean up the Liu family's new house, and the ladies in the yard helped to make the wedding quilt.

Enamel basins, thermoses, spittoons and other necessary items for a wedding printed with red wedding characters are also ready.

But something went wrong at this time - Liu Tianquan suddenly sent a telegram back saying that the leave to go back home was cancelled because of an urgent task.

Liu Tianquan decided to hold a simple ceremony with Huang Sen in the geological team and bring Huang Sen back if there was a chance.

Aunt Liu was looking forward to her son's return and was so eager that she almost fainted when she saw the telegram.

There was no other way, Li Aiguo could only find a way to hang up the phone with Liu Tianquan.

It was impossible to ask him not to participate in the mission, but fortunately there were only five days in between, which allowed Liu Tianquan to bring Huang Sen back.

You can go back on the same day and leave the next day and get the wedding done.

Liu Tianquan lost his father at a young age, and he knew that if his mother was not around to watch him get married, he might have regrets in the future, so he agreed.

When the residents of the courtyard learned about this situation, they were all surprised and expressed their willingness to help.

As agreed, the train arrived at 5:30 in the morning.

The residents of the courtyard were divided into two teams. The men's team, led by Nan Yi, went to the station to welcome Liu Tianquan.

Huang Sen needed to stay in the station for half an hour, and the wedding procession led by Li Aiguo would go to greet him.

Finally, the two sides met in the courtyard and held a wedding ceremony.

When Wang Dagui heard what Li Aiguo said, he said angrily, "Yi Zhonghai is in Aunt Liu's room right now, trying to be the master of ceremonies."

"Haven't we agreed that we don't need a host and can just hold a simple ceremony?"

As soon as Li Aiguo said this, he realized that he seemed to have done something stupid.

Generally speaking, the host at a wedding is either the leader of the unit or a respected relative.

No matter which one it is, it is extremely face-saving.

Because Yi Zhonghai made a mistake some time ago, he has been in a "retreat" state recently, otherwise he would not have stayed away even when Jia Dongxu was bullied.

He showed up now, no doubt he was going to pick peaches.

"Sister-in-law, our children's marriage is a major event in life, we must not be careless, otherwise we will regret it for the rest of our lives.

I'm the highest-ranking worker in our compound, and also a senior official. As the master of ceremonies, I will definitely make sure everything goes perfectly for you.

With me as a role model, Tianquan will be able to make further progress in his career and have a happy marriage after getting married."

It has to be said that Yi Zhonghai is particularly good at manipulating people's hearts.

What Aunt Liu is most worried about now is that something goes wrong at the wedding ceremony and that relatives and friends will criticize her behind her back.

But Aunt Liu was not someone who was oblivious to what was happening outside. Although she seldom expressed her opinions on weekdays, she was well aware of the situation in the compound.

If I choose Yi Zhonghai, I won’t be able to explain to Li Aiguo.

Seeing that Aunt Liu was hesitant, Yi Zhonghai had no choice but to continue persuading her.

At this time, He Yushui was a little impatient: "Uncle, you are a seventh-level fitter and an uncle, that's all right, but you don't have any children. If Brother Tianquan gets married and can't have children like you, that would be terrible."

Before he finished speaking, He Yushui made several "Pooh" sounds continuously. The disgust on his face made the aunties watching nearby couldn't help but laugh out loud.

Originally, the host of the wedding did not need to be a blessed person, but Yi Zhonghai wanted to show off his advantages and ended up falling into a trap.

The key is that Yi Zhonghai cannot get angry at this time.

He took a deep breath and said, "Besides me, there is no one else suitable in our compound, right?"

"Who said that? I think Brother Aiguo is quite suitable." He Yushui puffed out his chest and said, "Brother Aiguo is a fifth-level driver and has won the title of National Advanced Train Driver. How can he be better than you, a seventh-level fitter?
Brother Aiguo is the captain of the neighborhood patrol team, he is no worse than an old man like you, right?

The most important thing is that Brother Aiguo has a son!"

He Yushui stabbed Yi Zhonghai in the chest again without hesitation.

Yi Zhonghai was so angry that he almost felt dizzy and fainted.

"Master, let me help you." Jia Dongxu joined in the fun and quickly supported Yi Zhonghai.

Yi Zhonghai knew that he could not be the master of ceremonies, so he made an excuse of feeling unwell and asked Jia Dongxu to help him back.

As soon as they left, Li Aiguo came back.

"Where's Yi Zhonghai?" Li Aiguo looked bewildered. "He's sick, Aiguo, I'll have to trouble you to be the master of ceremonies," Aunt Liu said as she stood up.

What could Li Aiguo say? He could only agree without hesitation.

Xu Damao was watching from the side with envy, and whispered to Liu Lan: "Yi Zhonghai got beaten up but still couldn't get the spot, but someone else took the initiative to give it to Aiguo. Tsk tsk, I'm so jealous."

"You, don't think too much. Just be careful of Jia Dongxu." Liu Lan tapped Xu Damao on the forehead.

Xu Damao always felt that Jia Dongxu was secretly following him recently.

Because he couldn't figure out the reason and had no evidence, he could only tell Liu Lan secretly.

"Don't worry, I can deal with Jia Dongxu with ease." Xu Damao did not take Jia Dongxu seriously.

Before I knew it, it was four o'clock in the morning.

At this time, on a train rushing from the border, the lights were dim and the passengers were staggering in deep sleep.

Liu Tianquan quietly held Huang Sen's hand.

"Huang Sen, don't worry. Although I only have an old mother and a younger sister at home, I have a group of good neighbors. They will definitely arrange our wedding properly."

Huang Sen pulled his hand out shyly, and nodded with a blushing face: "I don't care about this, but I'm worried that my mother will look down on me as an orphan."

Huang Sen's parents were members of a geological team affiliated with the Western Academy of Sciences before liberation.

We have traveled deep into Sichuan and the southwest region to investigate mineral resources and geological conditions and explore mineral reserves.

During an exploration, he was killed by local bandits.

Since then, Huang Sen became an orphan and grew up under the care of several friends of her parents.

Nowadays, when a woman's parents are not around, she is often considered to be unlucky to her parents and a jinx.

That's why Huang Sen is so worried.

Hearing Huang Sen’s worries, Liu Tianquan felt both distressed and amused.

"Don't worry, my mother is not the kind of person who believes in feudal superstition."

With an uneasy mood, the train whistled twice and slowly stopped at Beijing Station.

Liu Tianquan left the station early as planned.

Huang Sen stood on the platform waiting for the team to come and welcome his new bride.

It was early morning at this time, and the passengers who got off the train left the station one after another, and the number of people on the platform gradually thinned out.

A large GAZ truck emitting black smoke was driving towards us from a distant passage.

When Huang Sen saw the large truck coming towards her, she deliberately took a step back and stood on the steps.

Suddenly, a GAZ truck stopped in front of her with a click.

A young man in a gray Zhongshan suit jumped out of the cab and greeted Huang Sen enthusiastically: "Sister-in-law, are you anxious waiting?"

Huang Sen looked at Li Aiguo, then at the GAZ truck. When she noticed the big red wedding character on the truck, she realized that this was the person who came to pick her up.

"You must be the patriotic brother. I often hear Tianquan mention you."

Faced with the large truck that came to pick up the bride, Huang Sen seemed a little at a loss.

At this time, another train was coming and the passengers were expected to get off soon. The conductor who was responsible for maintaining order on the platform gestured to Li Aiguo.

"Thank you, Brother Zhou. I'll leave right away!" Li Aiguo waved at him and opened the car door: "Sister-in-law, let's go back."

"Okay, okay, okay"

Although Huang Sen is not the kind of person who loves vanity, he still feels a little proud at this moment.

How could an average person drive a truck to pick up the bride, let alone drive a truck to the platform.

More importantly, as Liu Tianquan's brother, Li Aiguo is willing to go to such great lengths, which is enough to show that the man's family values ​​her very much.

The attention of others is particularly important to a woman who has been homeless since childhood.

But this seems a bit irregular.

Although Huang Sen has been working in border areas for many years, he knows that large trucks should not appear on the platform like this.

Huang Sen opened the door of the truck and got in.

The truck did not drive out of the exit, but turned a corner, drove along the platform for a while, and stopped in front of a freight train.

"Sister-in-law, wait a moment, I still have some work to do here."

Just when Huang Sen was at a loss.

Li Aiguo had already gotten off the train. He took out the documents from his bag and waved to the material specialist in charge of unloading the freight train: "Has the batch of goods from the Shiqiao Market Management Committee arrived?"

"Is this the goods from the Shiqiao purchasing point? It's here. Please wait a moment." The material specialist took the documents from Li Aiguo and took two packs of cigarettes at the same time, and put them into his pocket without leaving a trace.

Then he called two loaders to unload dozens of wooden boxes and load them into the trunk of a large truck.

He also proudly reminded the loaders to handle the goods with care.

After dozens of wooden boxes were packed, Li Aiguo signed Wang Dagui's name on the receipt and then took the exit pass.

The pass contains the quantity and train number of the goods. When leaving the station, the staff will verify them before letting them pass.

Seeing this scene, Huang Sen’s worries were finally put to rest.

Although she didn't know what happened to the cargo, the truck's appearance at the train station had formal procedures.

Li Aiguo didn't intend to drive the truck to pick up Huang Sen, it was just a coincidence.

In the past two years, the trade line from Guangzhou to Beijing has been running smoothly.

Because Li Aiguo specifically instructed to keep a low profile, the amount of goods shipped each time was not large.

It’s just that recently there has been a bumper banana harvest in Dashi Commune in Yangcheng.

The grain crop harvest was poor this year, and Dashi Commune urgently needed to sell bananas in exchange for grain.

Since the start of cooperation, Dashi Commune has never shortchanged us or sold inferior goods as good ones, and is an excellent partner.

This led to the large-scale banana trade of dozens of tons.

The truck sped all the way back to the gate of the courtyard.

Chen Xueru and several female comrades who were welcoming the bride had been waiting there for a long time. When they saw Huang Sen get off the car, they all went to greet him with a smile.

Li Aiguo completed the task of picking up the bride and drove the truck into the collective scrap purchasing shop in Nantongluo Lane.

Wang Da Kui and Zhou Xuan heard the sound of the truck and opened the door of the warehouse.

After transporting bananas five times in a row and finishing the work at the waste disposal point, it was already eight o'clock in the morning.

The truck was driven away by Zhang Tieniu from the truck transport team.

The goods trade spans thousands of kilometers and several provinces and regions, and involves people from cooperative members to purchasing agents, directors and deputy directors of the management committee, freight handlers at the Yangcheng Railway Freight Station, and truck transport team drivers.

These people have formed a dense fishing net around the trade route, enough to ensure that no traces are left.

Wang Da Kui was counting the batch of bananas in the warehouse and felt sincere admiration.

Being able to connect so many people together, Patriotic Brothers is truly an extraordinary person.

At this time, the extraordinary Li Aiguo had to fulfill his duties as the master of ceremonies, so he did not even have time to rest and hurried back to the courtyard.

Although Liu Tianquan did not hold a wedding banquet, many relatives and friends still came.

Due to the special nature of Liu Tianquan's work, his unit did not send anyone to attend, but the subdistrict office still received a notice from the exploration team.

Director Wang of the Sub-district Office came to attend the wedding with several leaders of the Sub-district Office.

At 10:30 in the morning, Li Aiguo found a tin loudspeaker and walked into the crowd to announce the start of the wedding.

Liu Tian, ​​wearing a brand new blue and black work suit with a big red flower on his chest, walked into the crowd accompanied by Xu Damao and Nan Yi.

Huang Sen also tidied himself up at this time, pinned flowers on his head and chest, and tied his hair into a ponytail.

Her skin is a little dark, but after applying some lotion and combining it with her strong physique, she has more temperament than the average city girl.

"The couple is getting married."

The gifts they exchanged were quite interesting. They were two geological hammers used for geological exploration.

"bow."

They both bowed to the photo frame.

Li Aiguo then began to speak loudly: "The revolutionary wedding is held by the revolution, the four seas are raging with clouds and water, and the five states are shaking with wind and thunder.

Comrade Liu Tianquan and Comrade Huang Sen are not only partners joined hands by love, but also like-minded comrades-in-arms.

As geological exploration workers, they have devoted their youth and passion to the vast land of the motherland without reservation.

Those unknown valleys and those sparsely visited wilderness have witnessed their love and dreams flying together, and their struggle and perseverance going hand in hand.

Now, with everyone's common expectations, they stand here.

Therefore, as the master of ceremonies, I hope you will continue to move forward side by side on the great journey of geological exploration and contribute to the construction of our motherland! "

As soon as he finished speaking, thunderous applause broke out at the scene.

He Yushui was jumping up and down there, shouting at the top of his voice: "May you have a baby soon! May you have a baby soon!"

Aunt Liu sat there, looking at the well-matched couple, and quietly took out her handkerchief to wipe away her tears.

She seemed to have more white hair than before.
-
Liu Tianquan and Huang Sen stayed in the courtyard for one night. The next day, under the reluctant gaze of Aunt Liu, they carried their luggage and boarded the train to the border.

The train started moving, and the wheels rolled up a cloud of dust, and Aunt Liu's eyes were dazzled again.

In the courtyard, Jia Zhang was still feeling depressed about not being able to have a wedding banquet, and she grumbled quietly, "What's the point of raising such a son? He's always away from home. He's far worse than my Dongxu."

Jia Dongxu nodded repeatedly: "Mom, don't worry, I will buy you some painkillers in a few days."

The Jia family is having a hard time now. They don't even have money to buy food. Jia Zhang hasn't taken any painkillers for two months.

But she also knew that Jia Dongxu had no money: "Dongxu, where did you get the money?"

"Mom, don't worry about it. I have found a good way." Jia Dongxu looked proud.

Qin Huairu was worried that Jia Dongxu would cause trouble, but she was afraid of being scolded, so she didn't dare to persuade him. She could only silently carry Xiaodang into the house.

After Li Aiguo finished arranging Liu Tianquan's wedding, he resumed his previous driving work.

In my spare time, I go to Beijing Chemical Industry to supervise the research and development progress. I live a happy life.

That day, I just came back from driving and met Wang Qingdian at the gate.

"Patriotism, it's done!" Old man Wang Qingdian danced with excitement.
