Chapter 35: I am a professional at making appearance
The two just talked and laughed and finished their meal. Gao Zhendong put away the things and said, "You wash the dishes."
"Why? I won’t do it.”
“Because you only cooked one dish and I took the bowl. There’s no way you can eat it for free.” Gao Zhendong smiled.
This feeling was very new to Lou Xiao'e, so she didn't have any resistance. She went to wash the dishes. While washing, she felt fierce in her heart: "Gao Zhendong, wait until I learn how to do it." It’s time to take a shower!” Thinking about how beautiful it was, she almost blew out her nose, but she didn’t realize what she was thinking about.
After dinner, Lou Xiao'e was about to go back. After all, she had been away from home all morning and couldn't play outside endlessly.
Gao Zhendong offered to give it to her, but Lou Xiaoe refused. She didn't want her home to be seen by Gao Zhendong. She was still a little sensitive to the ingredients, and always wanted Gao Zhendong to find out as late as possible.
Gao Zhendong didn't insist. After dinner, it was past one o'clock at noon. It was very safe. A big girl couldn't be left behind.
Lou Xiao'e returned home. Lou's father was reading in the living room. When he saw Lou Xiao'e's expression, he was stunned for a moment, shook his head, and continued reading.
Lou Xiao'e put her things away and went to the kitchen.
In the kitchen, the cook was packing up things after lunch. When Lou Xiao'e saw her, she first put her finger on her lips and made a "shh" gesture, and then asked quietly: "Sister Liu, can you do me a favor?" "
——
On Gao Zhendong's side, after Lou Xiao'e left, he simply took out the unfinished Internet article and continued reading. Don't tell me, it was really good.
I don’t know how long it took, but there was a knock on the door. Gao Zhendong opened the door and saw Liu Haizhong’s second eldest son, Liu Guangtian, a middle-aged man. Although everyone was familiar with him, this was a rare visitor.
While letting people in, Gao Zhendong asked: "Guangtian, what's the matter?"
Liu Guangtian was a little embarrassed: "Brother Zhendong, I have something to ask you for help."
Gao Zhendong looked at him: "Tell me, what is it?"
Liu Guangtian Qiqi Ai Ai said: "There are activities in our school, and I would like to lend you a bicycle."
Gao Zhendong didn't mind this, but it was a bit strange. Ordinarily, Liu Haizhong should have done this kind of thing himself I am telling myself this, and I shouldn’t be talking about this for a young man, because bicycles are a big deal at this time of year, and generally speaking, only the person in charge of the family can communicate about related matters.
Gao Zhendong nodded: "It's okay to borrow a car, but where is your dad? Why didn't he come and tell me."
Liu Guangtian's face changed: "He doesn't want to."
It is said that Liu Haizhong prefers the eldest brother, and now it seems that it is not true at all. He is not willing to borrow a bicycle for the second brother himself.
Gao Zhendong is not used to Liu Haizhong's temper: "Guangtian, let's put it this way, I am willing to borrow the car, no problem, but you have to come and tell me as an adult, otherwise you are a young man, If anything happens while riding a bicycle, I can't bear to blame your family for that. Do you think that's reasonable?" Liu Guangtian lowered his head: "I know, Brother Zhendong, you are right. "
Gao Zhendong nodded: "So if you want to borrow it, go back and tell your family. Master Liu or your mother will come and tell me in person. I will borrow it immediately. , okay?”
Liu Guangtian nodded and turned back. Ordinarily, it's fine if his father doesn't agree, but it's not like his mother doesn't agree either. This family is also interesting, just two words: terrible.
Until Gao Zhendong rested in the evening, the adults of the Liu family did not say anything about this matter.
——
On Monday morning, as usual, there was a meeting of the scientific research team. Everyone counted the progress together. Two-thirds of the trial production and verification tests of the most important thermocouple materials have been completed. , the comparative test is about one-third completed.
Liang Fafa’s place, the repeatability test design required last week has been completed. According to Gao Zhendong’s three-level review requirements, Liang Fafa has done the verification himself and is preparing to submit it to Gao Zhendong for review. After Zhendong's review, it will be handed over to Lao Chen for approval. At this time, Lao Liang, who has completed the design, has already returned to the test work.
All the plans in front of the scientific research team are reviewed in this way. Lao Chen thinks this method is good and is preparing to form a system and promote it in all disciplines to change the past haphazard review of results, disorderly review organization and lax quality control. Chaos.
In terms of domestic management of scientific research and design projects, this was the situation from the early days of the founding of the People's Republic of China to the 1960s and 1970s. It was relatively backward. It was only gradually improved after reform. If you are interested, you can read the relevant memoirs of the 59 tank design team and the American General Motors Cooperation Jaguar light tank. There are many things that can be seen from the memoirs, which are not confidential public information.
Seeing that there were no major problems with the progress and work, Gao Zhendong announced that the meeting was adjourned and everyone continued to work.
He himself returned to the office. What was he going to do? Two things, one is to review the repeatability test design invented by Liang, and the other is that he wants to design and make the secondary instrument of the thermocouple himself.
To put it simply, a secondary instrument is an instrument that converts the sensing signal of the sensor into data that ordinary people can understand. Because it has one more conversion compared to the primary sensor, it is called a secondary instrument.
People can often see some meters showing the operating voltage and current of the equipment on various PLC electrical control cabinets, which may be pointers or digital displays. These meter heads are typical secondary meters. Of course, secondary meters are much more than these.
When the sensor is not connected to the automatic control system, one of the simplest ways to use it is to connect it to a suitable secondary meter and watch it directly.
If the thermocouple studied this time is first promoted and used, the simplest and most convenient way is to match it with a secondary instrument for front-line production workers to check at any time during the production process. It is low cost and quick to produce results.
What Gao Zhendong plans to make is a secondary meter with an analog display, which is somewhat similar to the common analog multimeter in the past.
As for why we don’t design a more intuitive digital meter, the main reason is not that there are no digital display tubes. In fact, there are already digital Nixie tubes at this time. Not to mention, they look good when lit up. There are some in the 21st century. Retro-style electronic devices are still using this stuff.
The main problem is that the thermocouple output signal is a thermal electromotive force, a typical analog signal. It is very troublesome to convert analog signals into segment selection or bit selection signals for digital display without the cooperation of digital circuits. In these days, digital circuit components are not so easy to get and are even almost non-existent in China.
This is also the reason why Gao Zhendong wants to do secondary instrument design by himself. There are not many people in the technical department who understand automation. You know, in the automation major of Pudaokou Institute of Technology, Gao Zhendong’s 55th class is the first 1st year, other universities are similar, or even later.
To put it in future Internet terms, Gao Zhendong is a leading automation talent with a professional background after the founding of the People’s Republic of China. Therefore, Gao Zhendong can say without humility in this era: I am professional in making instruments. .
