The ups and downs of life in the Siheyuan

After running for 3 consecutive days, the 911 machine did not have any problems.

This is simply unimaginable for a tube computer. In the past, it could run for one hour without any problems, which was already a very good result.

Most of these failures are due to tubes.

This is related to the current backward manufacturing process, and it is even more related to the way of use.

The individual lifespan of an electronic tube is approximately 1500 to 3000 hours.

This is a statistic, which means that every 1500 to 3000 hours, a failure may occur.

Failure may occur at the first second or at the last moment.

The statistical method is the probability of an abnormality occurring with 3000 electron tubes running for one hour.

So, if you use enough tubes, the probability of failure increases every hour.

The main cause of electronic tube damage is high temperature.

If the temperature is not released and accumulates to a certain extent, an avalanche effect will occur, and the electronic tube will fail instantly.

Therefore, just a simple temperature zone modification can greatly increase the average service life of 911 computers.

Go past a ventilation duct and set up a blower with sufficient power at the far end to extract air.

Due to the layout of cables, vortices will form in many parts of the tube, and the hot air will only rotate in a small range.

Only a small portion of the heat is removed.

Therefore, the electronic tube cannot get good heat dissipation.

Later generations adopted the design of special air ducts for the vortex effect.

Li Yuan's renovation plan this time is to set up an independent air duct to force air to enter from the front, then flow through the surface of the electronic tube and be discharged from the back.

The changes are not big, but the effect is obvious.

At this time, Li Yuan mentioned the eddy current theory again, and the teachers and students in the laboratory were truly convinced.

"Okay, it has been running stably for so long, which is enough to show how powerful 911 is.

And the calculation speed has increased so much, you are amazing! "

Principal Jiang and Vice Principal Dong appeared in the laboratory together, and they were really shocked by the good news.

"I will report the good news to my superiors in the afternoon, no, shortly.

You are all good, especially Li Yuan. Although his change is inconspicuous, it can be said to be the finishing touch and a wonderful touch.

Therefore, we must emancipate our minds and not be bound by the past experiences of foreigners.

Dare to try, dare to innovate, and dare to make breakthroughs! "

Principal Jiang's speech aroused loud applause from teachers and students.

Three days later, a large number of experts came to the laboratory and began technical identification work.

After a day of demonstration, explanation and defense, the 911 machine successfully passed the expert technical appraisal.

The long-term stable operation and calculation speed have become the biggest highlights of this appraisal.

The next step was to arrange production. The superiors decided that the Kyoto Radio Factory would be responsible for mass production.

The Radio Factory has been engaged in the production of tube computers since 1958 and has accumulated a lot of experience in computer manufacturing.

Although there are a large number of drawings and design documents, the computer department still sent a technical team.

The team was led by Director Jin, and 15 teachers and students participated in the production of the prototype.

Li Yuan was among them.

When discussing candidates, huge differences occurred.

Especially the teachers who were not included in the list had very strong opinions on Li Yuan's selection.

The main reason is that Li Yuan is just an auditor, so how can he represent the computer department?

Everyone read that right, it means "going out".

This is the fastest computer in the country, and it may be published in the national newspaper in a few days.

If you go to a radio factory to make prototypes, you will definitely record a lot of pictures and film and television materials.

These are all honors. There are only 16 people in total, and each one is the leader of each module. He, Li Yuan, is still just an auditor.

How to be selected and what are the qualifications for selection.

This is human nature, when you work, you take it for granted. When interests are shared, there will be distance and distance.

In the end, Vice President Dong personally came forward to finalize the list.

Before the expedition, Li Yuan obviously felt unmotivated in the laboratory.

Although everyone is still very polite on the surface, they are really polite and no longer as close as before.

Li Yuan knew why, but he didn't care. It wouldn't be comfortable for him.

But if he were asked to give up voluntarily, that would be impossible.

Influence is created by results one after another.

Only when you step to the front desk will everyone see your abilities.

Only then will I remember you and give you more opportunities.

If he gives up this time, his reputation will be limited to the laboratory.

As time goes by, it will gradually be forgotten.

Setting off three days later, Li Yuan greeted Director Jin and arrived at Room 412 on the top floor of the Motivation Department office building.

The place is being renovated, the walls are all painted with cement, and then a layer of white paper is glued on.

The biggest change is to add an air filtration system and an exhaust system.

The filtration system is relatively simple, with two layers of thin sponge filled with large particles of charcoal in the middle.

The air outlet is facing the workbench, and the air outlet has only a layer of fiber filter.

Although crude, it does work.

All window gaps should be sealed with glue to prevent air leakage.

This kind of environment is probably unbearable for most people in Xia Tian.

Now there is no air conditioning, and we dare not use fans. In such a closed environment, ordinary people cannot last for an hour, and they have to run out for fresh air.

None of this matters to Li Yuan.

After practicing the technique for more than two years, he has already become immune to cold and heat.

Li Yuan entered the room. The decoration was coming to an end. It was August, which was the hottest time.

The doors and windows were wide open, and the masters were working naked and sweating.

Seeing that it was Li Yuan arriving, the leader came over with a smile.

"Teacher Li, it will be completed in two days. Please see if there is anything inappropriate."

Although he knew that Li Yuan was a student, Director Li repeatedly emphasized that this was a laboratory for the young people in front of him. How could he dare to look down upon him.

It is safest to call you teacher.

"Master Gao, everyone is tired." He took out the popsicles from his "sack bag" and distributed them to everyone one by one.

At Master Gao's signal, the worker thanked him profusely and took the popsicle.

Li Yuan took the opportunity to walk around the room, scanned it with his mind, found no flaws, and left.

A worker in the laboratory whispered: "Boss Gao, this little teacher looks so smiling, why do I always feel uneasy?"

"Yes, especially when he was inspecting the decoration, it felt like he was being glanced at by a tiger."

"Well! This teacher is incredible."

. . . . . .

A week later, in a workshop of the radio factory.

A group of people from Huaqing University are conducting handovers with factory technicians in batches.

Li Yuan is responsible for system joint debugging, wiring and wiring.

"Technician Tang, look at the drawings and see if there is anything unclear?"

"Teacher Li, we have digested and absorbed most of the drawings in the past few days, but we have two questions.

First, why do we need to cover the cables with iron pipes?

Second, why were the previous welding points changed to joints? "

"Technician Tang, most of these cables are routed close to the ground. In order to prevent mice from chewing them, I recommend covering them with iron pipes.

The purpose of changing the wiring solder joints to plugs is to facilitate production, manufacturing and later maintenance."

"First of all, I understand.

However, I think that although it takes a lot of time to produce, welding is more reliable than joints."

"I don't quite agree with your point of view. Who said welding is more reliable than joints?"

“That’s what Big Brother says, they think joints tend to come loose”.
