Chapter 220: Dangerous job

This ring also has the biggest function of installing an electric pacemaker. This is a powerful device. If someone does not turn him off, as long as the pipe is exposed to the air, it will be subject to a thousand Clicking on volts, this voltage can speak of an adult's corona but will not cause death.
The role of microorganisms is to carry these graphenes to fill the entire pipeline gap, preventing pipeline rupture problems caused by uneven pressure. What's more, he can turn the graphene that has been formed into a semi-solid and semi-liquid state again, so that foreign graphene can be tightly combined with the formed pipe.
After about ten minutes of microbial activity should have been completed, the welder said that a red and black wire was connected to the two ends of the container. Later, they took out two copper wires and connected them to the two sides of the gap. At this time, the welding personnel also climbed up the tunnel, and this movement occurred at the same time at the five interfaces.
"Everyone evacuated ten meters away." At this time, as the chief engineer of the project, Wei Donglai gave orders.
"The power supply has been linked."
"Boost device is OK."
"The line is OK."
"Everything's OK, electric shock."
"Electric shock." Wei Dong ordered, and a spark flickered at the seams.
"Reported that Wei Gong was shocked."
"The power is off."
"The boost device shuts down."
They repeat this set of processes more than ten times a day, but even if they are familiar, they still follow the regular process every time. After all, this is a high voltage of 100,000 volts, which is no joke.
"Yang Yuan, lead the inspectors and carry out the inspection." Wei Dong ordered only five minutes later.
"Yes, follow me." Yang Yuan greeted the two students from Star Academy who were wearing the same discharge suit as her. Except for the three persons who went to check, all others stayed in place and could not enter the ten-meter range of the pipeline. About twenty minutes later, Yang Yuan's inspection report came from the communication equipment: "The seams are perfect, everything is normal."
After Yang Yuan's sentence was finished, at this time, all the personnel started their work again, and they would do this many times a day.
This section of Wei Donglai's responsibility is basically flat, so their work is not very hard. The hardest part is the first group and the fourth group. All the routes in the first group are all in the mountains, so they need to make a tunnel through the mountains, so their construction is very difficult. The fourth group of routes are all in the desert, the others are good, but the environment is worse. The second group is almost the same as Wei Donglai, so their work progress is almost the same as Wei Donglai.
The high voltage of 100,000 volts is to let all those microorganisms die. This can cause graphene in a liquid state to instantly solidify, which will greatly reduce air bubbles at the joints. The developers of this technology are the first students. They also developed this method in a very good situation, but it is a bit dangerous. However, Star City cannot wait any longer. With the deepening of aerospace engineering, the processing and manufacturing of some parts has increased the demand for water, so it is directly used.
At the time when the first student was designing this scheme, they also went for the feasibility and did not do something about operational safety. Therefore, after the previous staff members responded to this problem, He Miao, as the main designer of this project, also broke his heart. Until now, he has not found a method to replace the electric shock.
Chen Qiang also heard about this, but he didn't do anything. This matter is too small. If he is allowed to solve it, he can make dozens of solutions.
Now he is making some preparations for the assessment of this Starry Academy. The assessment time is only one month, so the questions for this assessment should not be too difficult and the time required should not be too long.
"Teacher, how do you think we will take the test this time, separately or together?" Chen Qiang has some headaches, so he can only turn to his teacher.
"For a month, I think it's better to take the test separately. After all, if it was the big problem of the last session, one month would not be enough." Kong Ru is also considering this issue these days.
"Then take separate exams, but what do we take. After all, there are a lot of people who need to be eliminated in this session, so the students in this session cannot use some of the results of our Star Academy." Chen Qiang said distressed.
"This is also a problem, don't you say I really forgot, those principals just came to see what they learned?" Kong Ru said with a smile. Concerning this matter, Confucian can only help but can't help. You must know that the first student of Xingkong Academy was a topic created by the founder Chen Qiang. You should know that the four deans of Xingkong Academy had already prepared the assessment project, but they were directly stunned by Chen Qiang's big plan. These recognitions are not ordinary, so this is the bitter fruit of Chen Qiang's own cultivation ~ www .EbookFREE.me ~ can only be swallowed by himself.
"They have been impatient for a long time, but they were stopped by me. I just let them come at the final reporting stage." Chen Qiang said helplessly. For these 1,500 students, these principals are very concerned. Basically, they have to call each week to ask.
"Well, I can't sit here right now, I'll go back first, you can hurry up as fast as possible, the students are already waiting to see." Kong Ru left the office with a smile. Chen Qiang wrote the first assessment question after a long time of thinking-3D printing.
The use of 3D printing in the world has been extensive, but the current 3D printing technology has been restricted in many aspects, such as the limitation of materials and the limitation of machines. Especially the limitation of the machine, which directly led to the promotion of 3D printing technology.
3D printing technology has achieved a certain level in reconstructing the geometry and function of objects. Almost any static shape can be printed, but those moving objects and their clarity are difficult to achieve. This difficulty may be solvable for manufacturers, but if 3D printing technology wants to enter the ordinary family, everyone can print what they want, and the limitations of the machine must be solved.
So this is a project that Chen Qiang gave to the students of the Mechanical Institute, let them solve this problem, and let the 3D printing technology truly enter every family and become an essential article for every family. 3D printing technology has been widely used in Xingkong Group, and now many parts are manufactured using 3D printing technology. But Xingkong Machinery Research Institute is researching and developing large 3D printers, and Chen Qiang intends to let these students enter the field of small 3D printers.
