Chapter 222: Not drunk

"Single-axis piezoelectric gyroscope", as the name implies, is a vibrating gyroscope based on the piezoelectric effect of certain materials, using piezoelectric sheets as transducers to excite the vibrating element to vibrate and detect Coriolis force vibrations. instrument.
The materials it uses mainly include PZT ceramics and piezoelectric quartz crystals, and piezoelectric materials such as lithium niobate and lithium tantalate can also be selected.
Among them, piezoelectric ceramics are the most widely used. Its greatest advantages are high permittivity, large electromechanical coupling coefficient, easy processing, and low price. It is the material of choice for vibrating gyroscope force-electricity conversion.
This product was first successfully developed by General Electric of the United States and tested on its Navy F-4J aircraft and Boeing aircraft. Then it was first equipped in the Air Force A-10 aircraft stabilization system and put into mass production at the same time.
Although this achievement was first successfully developed by the United States and put into practical application, in fact, Huaxia has accumulated a lot in this field, and the performance and application of high-end products have exceeded the international leading level. However, in the low-end civilian field In the market, even in the era before Tan Zhenhua's rebirth, more than 90% of China's domestic market was still occupied by foreign products. This has to be said to be a big regret.
Huaxia began to research this kind of products in 1970. At that time, it was mainly developed for the task of miniaturization of missiles. The main product development and undertaking unit was the Shijiazhuang 4054 Research Institute based on the development of device products.
This 4054 Institute, located in Shijiazhuang City, Beihe Province, is also a research institute under the Fourth Ministry of Machinery. Although it is not as large as 4014, it has more than 2,000 people. Its main focus is on various crystal devices.
In fact, Tan Zhenhua has dealt with them in his previous life and used a lot of components. However, due to the limitation of his professional field, most of his products are concentrated in the area of ​​crystal oscillators, and he has really never touched gyroscopes. When Zheng Xiangqing talked about it, he didn’t think of them for a while. This time he was reminded by Song Wenhua. He slapped his forehead and said regretfully:
I should have thought of them a long time ago. I was negligent, Teacher Song, thank you Reminder, I will find a way to contact them.
Tan Zhenhua had a lot of acquaintances and friends in 4054 in his previous life. According to his age, many of them should already be working there. However, he thinks about it and it is not suitable for him to come to the door rashly. It is through his own The other teacher is fine.
The two teachers, Song and Guo, have already helped themselves with a lot of work, but the academician of Ben University has not done much to help him recently. No, you must not let him idle. You have to find a reason to let him go. Tan Zhenhua made the decision secretly because he was a thief ship.
Zheng and Pan, who had been listening to Tan Zhenhua talking on the phone, came up and asked, "Zhenhua, how about it? Is there a show?"
Tan Zhenhua raised his right hand, snapped his fingers and said: "It's done! Teacher Song has agreed to the carbon fiber processing. Although the conditions are a bit high, it is nothing. Anyway, our profit is large enough to be fully supported. As for The gyroscope, I also know the production unit, which is a research institute of our fourth machine department. If you want to, you should be able to buy it."
Pan Weiguo slapped Tan Zhenhua's shoulder with a slap, so that he was just a stagger and almost fell a dog to eat shit. He grinned and said, "You know that you have a solution for Sanbao."
Tan Zhenhua hurriedly pushed away Pan Weiguo's claws and yelled, "I said Brother Erbao, can you lighten it next time, just your bear paw, you can slap me in the ground with a slap!"
Pan Weiguo rarely joked back: "It's okay, I'll take it in and I'll pull it out for you. It can grow longer."
Tan Zhenhua had to roll his eyes at him and put his up.
Zheng Xiangqing smiled and said: "Fortunately, Zhenhua, you are here this time. This time the problem is basically solved. Now we wait for Professor Wang's people to come and build the battery factory, and we can officially start construction!"
Pan Weiguo yelled: "Starting, I'm hungry. Let's find a place to have a good meal today. One is to receive the wind from Sanbao, and the other is to celebrate our official start. Today, Big Boss Tan has a treat!"
Tan Zhenhua smiled and nodded. As the biggest boss of the company, this job is the job he is most willing to do.
It's a pity that Pan Weiguo's belly is destined to be hungry for a while, because just when they were about to go out looking for food, they received a call from Xie Guangfeng that Bao Yan was about to give birth and had already been in the hospital.
Hearing the good news, the three of them rushed to Liushi People's Hospital when they had no intention of eating.
When they saw the old couple of Xie Guangfeng at the hospital, they knew that Bao Yanlai had already entered the delivery room, while Xie Guangfeng was circling around the door of the delivery room and grinning. He was pleasantly surprised when they saw Tan Zhenhua coming. Go and ask: "Zhenhua, you are here too. When did you arrive, why didn't you say hello in advance?"
Tan Zhenhua smiled and replied: "Thanks to the director, I just arrived not long ago, so I went to Xiang Qing and sat there. After hearing the good news, I hurried over. Actually, I planned to go again tomorrow. See you. How is it? How long has it been for my sister-in-law to go in? Is everything going well?"
Xie Guangfeng said in a row: "Successfully, Yanlai, she is in good health. The doctor has just said that the baby's fetal position is very normal, and the delivery is no problem."
Tan Zhenhua also thought about it. Bao Yan’s first child was born in the old woods of Myanmar Yu’s mountains. Everything went well. This is the second child. Besides, China’s medical conditions are much better than Myanmar Yu’s, so it should be even more okay. , He smiled and said to Xie Guangfeng: "Then congratulate you in advance, Grandpa Xie!"
With this scream, Lao Xie's eyebrows and beard were all smiled, and Haoxing said: "Tongxi, Tongxi, in a few days when Yan comes out of the hospital, they will all come to our house for dinner, Zhenhua, don't worry. Go, you must come too!"
Tan Zhenhua hurriedly replied: "It must be, I am here this time, I planned to stay a few more days."
Several people were talking about the excitement outside the delivery room, and saw a nurse holding a small baby and pushing the door out, shouting: "Who is Bao Yan's family member?"
Xie Guangfeng hurriedly greeted him and said, "I am who I am, and Bao Yanlai is my daughter-in-law."
The nurse looked at him up and down, then put the baby in his arms into his arms and said, "This is your granddaughter, don't worry, mother and daughter are safe."
Xie Guangfeng took the little baby carefully, with a doting look on his face, and all of them leaned forward to look at the baby, and saw that the little baby was sleeping with wrinkled and red skin, with closed eyes and pouting mouth. It was fragrant, and the thin breath caused the little nose to twitch and twitch, which was very cute.
Pan Weiguo had never seen a newborn baby. He leaned forward and watched for a long time. He frowned and said, "The baby born here is so ugly. Why is the skin wrinkled than an 80-year-old woman, and why is this so red? Will it be too dark when you grow up? It's not good for girls to be too dark."
Tan Zhenhua replied casually: "What do you know? Children are born like this. It will be fine after a few days. The skin is red and red. It must be white when I grow up. I think it’s just me. Brother Li and sister-in-law Yanlai’s genes must be big beauties in the future!"
Xie Guangfeng’s wife laughed and said,
I didn’t expect Zhenhua to be very young. This pair of babies knows a lot about things, like someone who came here.

Tan Zhenhua knew that he had said the wrong thing again, and he accidentally said the experience of his previous life. How could a 17-year-old high school student know this? Fortunately, his brain turned quickly, and his expression remained unchanged, and he responded: "I don’t know anything. I listened to my mother when I was nagging. She said that my skin was red when I was born, so I grew up. Bai, I said that my brother was black when he was born, he grew up, um, he grows black even when he grows up, she is also a doctor."
Everyone was amused by Tan Zhenhua’s words. Zheng Xiangqing laughed and said,
I’m really convinced. It turns out that the name of this little genius of Zhenhua is not for nothing. He even knows about giving birth. It can be said that "the top knowledge of astronomy and geography, the next knowledge of trivialities".
Lao Xie held the child and looked from the left to the right, but he was reluctant to let go. Until the nurse came out with Bao Yan who was lying on the stretcher, he finally put the child reluctantly next to Bao Yan.
Bao Yanlai had just given birth to a child, her face was exhausted, but her eyes were full of maternal brilliance, she put her arm around the child, looked down, and saw everyone outside the house, but smiled slightly, but When I saw Tan Zhenhua, I was still slightly startled, and then he said hello in a soft voice: "Zhenhua, you are here too."
Tan Zhenhua hurriedly stepped forward and said while helping the cart: "Well, yes, I heard the good news when I arrived, and I ran right away. If you have anything to say, wait until you are discharged from the hospital. Now everything depends on you and your baby. the Lord."
Bao Yan nodded, turned to Xie Guangfeng and his wife, and said with some regret: "Dad, Mom, it's a pity to be a girl."
Xie Guangfeng laughed loudly: "Lai, what are you talking about? In our Huaxia, boys and girls are the same, besides, we already have Nianhua. It would be good to have a girl. For you, it means having both children and daughters. ."
Bao Yan was relieved when she heard this. She, who had been educated in China since she was a child, understood very well the nation's persistence in inheriting the lineage and the seriousness of patriarchal thinking. Fortunately, she already had a mindfulness, and it would be nice to have another girl.
While listening, Tan Zhenhua pouted her lips, saying that Lao Xie, you are a duplicity. When she came back and heard that she had a grandson, she was so excited.
The nurse pushed Bao Yan and the child into the ward. Xie Guangfeng’s wife was busy following up to take care of it. It’s inconvenient for the elders. Xie Guangfeng looked around and smiled: "It’s a coincidence that Zhenhua is a rare visitor. The sun is not as good as the sun. Everyone hasn’t eaten yet. Let’s go out and find a place to have a drink to celebrate my granddaughter. By the way, Xiang Qing, you can call Laoshi and Muzi. Call Lao Gao, not drunk or return tonight!"
