In the office of the director of the Wucheng Industrial Committee.

Director Zhang Yuanwen is seriously revising a manuscript sent from the laboratory.

-- Tests of new equipment for training the ability to move metals.

Since Jiang Jiuling was on the third floor two days ago, he performed a glass drawing with a glass rod and an air cutting gun. Several experimenters in the laboratory drew a scoop according to the gourd, and increased the length of the glass fiber from more than ten meters to the current cardboard box after using up two bottles of acetylene and oxygen.

Now in the carton, there are hundreds of fiberglass with a length of about ten meters.

As Jiang Jiuling said, under the action of gravity, the technology of extracting glass fiber is so simple that even the uncle of the boiler can learn it. Its production cost and production conditions are so low that people feel like they are picking it up for nothing.

It is indeed the most suitable material for training the movement of metals.

One fiberglass, one metal ball.

A small hole should be made in the metal ball, and because the pipe has changed from the inner diameter to the outer diameter, the end and front end of the fiberglass must be erected with something. In this way, it is necessary to thread the metal ball into it before practicing.

It's not a hassle, the fiberglass itself is so elastic that you can pull it away from the shelf and put it back in before practice.

Now Zhang Yuanwen has a few prepared fiberglass shelves on his desk, and after he plans to revise the manuscript, he will send the manuscript to the province along with the training equipment sample, and then the provincial level will submit the manuscript to the [knowledge] scientific journal published by the Industrial Commission.

Zhang Yuanwen is sure that as long as the knowledge journal publishes this article. It won't take long for those domestic engineers to replace the maze exercise tube invented by Mr. Mao Sheng with fiberglass exercise equipment.

The price of a set of practice tubes in the former is hundreds of yuan, and novices can easily break the thin glass tube when practicing.

The fiberglass exercise equipment costs only one or two pieces, and there is no need to worry about damage, which is very suitable for novices.

Of course, this does not mean that Mr. Mao Sheng's invention is completely outdated, in Zhang Yuanwen's view, after the title engineers can skillfully move the metal ball, it is better to use glass to practice the tube.

Hundreds of fast sets of practice tubes are mainly expensive in accuracy, and if you don't pay full attention to the practice, the glass tube will be broken.

It costs ten yuan to break a glass tube, can the skill not rise fast?

Just as Zhang Yuanwen was considering the wording, someone knocked on the office door from the outside, and Zhang Yuanwen shouted in.

The person who came was a staff member in charge of equipment and equipment management in the committee, and he still had a document in his hand.

It was a little strange to see Zhang Yuanwen coming. Because there are four directors of the office and two directors in the industrial committee. This staff member is not under his own jurisdiction and does not have to report to him.

"Director Zhang, I have a document to sign here, and I would like to ask you about it. Ma Ke walked in and said politely: "Here's the thing, the two investigators appointed by the provincial industry yesterday are gone. ”

"They took the damaged Wang Mang-class caliper, but left the culprit of the damaged caliper here, which was the robot chariot that the students had worked together. ”

"Didn't it blow up along with the caliper, and they threw the broken tank to us after taking the picture, saying we'd take care of it ourselves. ”

"So on my side, I would like to ask for your opinion. ”

Zhang Yuanwen nodded, understanding the purpose of the Ma Ke member's visit.

A few days ago, the investigators of the Provincial Industrial Commission came over, and many people in the committee knew about it. This was not a big deal, and the two investigators went through the motions, and after a few meals and a day here, they went back with the damaged Wang Mang-level calipers.

Wang Mang-level calipers belong to the second class of special industrial tools, even if this kind of tool is damaged, the Industrial Commission must recycle it for the record.

The robot chariot was the culprit responsible for the damage to the calipers, and it was theoretically necessary to bring it back for the record.

It is estimated that the two investigators who came on motorcycles thought it was too bulky, so they just took pictures and threw it to the Industrial Committee of Wucheng for safekeeping.

With the departure of the two investigators, the events surrounding the calipers came to an end.

Of course, the Provincial Industry Commission will not seek compensation from the three students, and even if they want to expel them, the school has already taken the lead in expelling the three students, leaving them with nothing to say.

Two days ago, Zhang Yuanwen called Jiang Jiuling to the office, and then the two of them muttered for an afternoon, and many people in the committee heard about what fiberglass they had come up with.

Now that the robot chariot that Jiang Jiuling and his friends made up was left here by the investigators, of course the sensible horse scientist came to ask Zhang Yuanwen what to do with this chariot.

Zhang Yuanwen thought to himself that kid could even make fiberglass, and he didn't know what the robot chariot looked like, "What kind of chariot is that, I'll take a look." ”

The Ma clerk led Zhang Yuanwen to the door of the warehouse at the back, and if it was customary, the Ma clerk in charge of the equipment and equipment would sign the document and put the things left here by the investigator into storage. Once something is in storage, the end of waiting for it is to slowly rust, and finally after two years, the warehouse is full and is disposed of as useless waste materials.

Before he signed for the warehouse, the Ma clerk put the things at the door of the warehouse.

So as soon as Zhang Yuanwen entered the door, he saw the robot chariot lying on the ground.

It is now turned into two parts, one for the frame and one for the shell.

It is slightly larger than a children's car, and the frame has four wheels, and the frame is welded from hollow iron pipes with the thickness of the index finger, and you can also see the motor, gears, chains and other parts inside.

But the frame was bent, it had a huge break in the middle, and all kinds of wires and steering rudders were blown apart.

The four wheels were intact, and Zhang Yuanwen took a closer look and found that the wheels were a little familiar, as if they had been removed from a store freezer.

The most eye-catching thing is the shell next to it.

At the time of the explosion, the vehicle did not have a casing installed, so the casing was intact.

The shell, like the Beetle, is covered with a bright red coat of paint. In the middle of the shell, there are also four names of the combat vehicle written in yellow paint.

- Crimson Arc.

Zhang Yuanwen picked up the shell, and the weight of the hand was not light.

He wondered how the three students had managed to make the chariot arc and be so smooth to the touch.

Flipping to the back of the shell, Zhang Yuanwen found three flat welds running through the entire shell.

"Beautiful welds. ”

Zhang Yuanwen stroked the weld seam and admired it: "Although there is no technology inside this chariot, it seems that there is no scientific and technological technology, it is far-fetched to say that it is a robot chariot. But you look at the frame, the few parts that remain, they are not laid out in a regular way. ”

"This shell is actually made of three pieces of iron sheet that are forged little by little, and finally welded together. ”

"There are still traces of forging at the edges, and a seventeen-year-old student can be forged like this by hand, and it will be amazing when he grows up. ”

Zhang Yuanwen's appreciation for Jiang Jiuling became even stronger.

In addition, he has also read the report on the incident that the investigation team asked Jiang Jiuling to write, and it was mentioned in the report that he completed the welding work of this tank alone.

Just punch this weld, and you can get twice as much work as an ordinary worker in any factory you go to.

Ma Ke reminded in a timely manner: "Director Zhang, then I won't sign this word?"

Without signing, this vehicle can not be put into storage.

"Signed. ”

Zhang Yuanwen showed a businesslike smile, "After all, this is something left by the Provincial Industrial Commission." ”

"We still have to go through the process, you have a piece of iron and a few wheels, sign these things and keep them on file. ”

"As for this tank. ”

"It's a pity to put it here to rust, I'll let Xiao Zhang send the chariot to where it belongs. ”
