Chapter 1063 About Maglev Technology
There are many small restaurants downstairs of Southeast Qijian Company.
At noon, Jiangnan and Bodequn had lunch at a small restaurant near Southeast Qijian Company.
Bai Dequn skillfully called the boss's wife to order dishes, looking like a native of Tianfu. Jiangnan admired him very much. This guy used to be in Qinhuai, but he didn't have any peppers.
Now that I have married a wife in Tianfu, my taste for eating has changed.
In the afternoon, Jiangnan and Bodequn went to Tianfu Construction. The two studied the construction plan and quotation of Tianfu Logistics Park, and finally set the profit margin at 18%, which was lower than the market conditions, but more than the construction projects for their own homes.
Southeast Construction Engineering undertakes its own projects, and the general profit margin is set at 15%. The reason why it takes 3% more is because Party A is Chuanxianglian after all, and Party A's management and coordination work is not Jiangnan itself, so it will cause certain management fees to increase and manual efficiency reduction.
After talking about the Sichuan Township Union, Bai Dequn talked to Jiangnan about the Nanxi Building in Tianfu. At the end of last year, Jiangnan and Qin Ximei came to see the triangular land. After that, Jiangnan told Bai Dequn about his thoughts and asked him to find a design company in Tianfu to be responsible for the subsequent design work.
For the building of his own, Jiangnan pays more attention to the practicality of functions. As for the appearance of the building, Jiangnan does not pursue innovativeness, simple and practical, and easy to maintain.
Now the drawings are out, and the construction can be started directly in early March just after Jiangnan has been confirmed.
After finishing work in the afternoon, Bai Dequn originally planned to take Jiangnan home for dinner, but Jiangnan still had to pay New Year greetings to Aunt Yan Yujun and Professor Luo Qunfeng, so he politely declined his invitation.
Yan Yujun knew that Jiangnan was coming in advance, so she was busy cooking at home early. When Jiangnan arrived, Yan Yujun was still busy in the kitchen.
Before the supper was finished, Luo Qunfeng pulled Jiang Nan and sat on the sofa and chatted.
Professor Luo said: "Jiangnan, school will start in two days. I didn't expect you to be so busy before school starts."
Jiang Nan said: "Uncle Luo, I came to Tianfu to see the projects that will be started this year. In fact, it is not too busy."
Professor Luo said: "Previously, your aunt asked me to help you find a small assistant in civil engineering. I will report to you in a few days. That child is a bit... special, but his grades and professional knowledge are very solid."
Jiang Nan was very puzzled: "Special, why is it special?"
Professor Luo smiled and said, "You can't say it's special, you'll know it when you see it."
After chatting for a while, Jiang Nan couldn't help but ask about magnetic levitation again.
Professor Luo said: "Jiangnan, since you are so interested in our magnetic levitation technology, why didn't you apply to our school at that time?"
Jiang Nan said a little embarrassedly: "Uncle Luo, I am actually more interested in civil engineering. I like magnetic levitation because I think this technology can subvert our travel methods in the future."
Professor Luo said: "Don't the demons build a magnetic levitation demonstration line? It started on March 1. Have you ever known about that project?"
Jiangnan said: "I have read the news about that project, but that project uses German room temperature and magnetic levitation technology, which is still different from the high-temperature superconducting technology studied at Southwest Jiaotong University."
Professor Luo said: "Actually, this is the case. Our high-temperature superconducting technology is actually very restricted by superconducting materials. The high-temperature superconducting we are talking about at present also refers to relatively low-temperature superconducting. It is actually an ambient temperature of more than minus 190 degrees below zero, so the material must be soaked in liquid nitrogen. The preparation and acquisition of liquid nitrogen itself requires energy cost. Specifically at the practical application level, the liquid nitrogen immersed in the superconducting material at the bottom of the train needs to be supplemented regularly, otherwise superconducting performance will not be obtained. If one day, our normal temperature superconducting materials can achieve a breakthrough, then there will be no such problem."
After hearing this, Jiangnan suddenly realized that the most critical issue was that if applied to the maglev suspension logistics system he had imagined, tens of thousands of small cars were shuttled through the tracks and just replenishing liquid nitrogen was a very heavy task and a very heavy burden.
Professor Luo did not notice Jiangnan's expression at all and continued: "So I said last time that this is a systematic project. It may require breakthroughs in multiple disciplines, multiple majors, and multiple technologies. It is still necessary for professionals to coordinate and coordinate to finally complete the integration. In fact, I think the future magnetic levitation should not be the high-temperature superconducting magnetic properties of liquid nitrogen as the cooling technology, but the superconducting magnetic levitation at room temperature. In fact, what is more complicated than magnetic levitation technology is the control technology of the train. I won't tell you in detail here."
At this time, Yan Yujun said, "Stop talking, wash your hands and have a meal, Jinyun and Jinpei, you two should turn on the TV as soon as possible. School will start in two days and you still watch TV."
The two little girls followed their mother to greet them, turned off the TV, and ran to the bathroom to wash their hands.
Just now, while my mother was cooking, my father chatting with Jiangnan, and in front of Jiangnan, my parents were embarrassed to care about them, so they watched TV openly for a while.
During dinner in the evening, Yan Yujun once again apologized to Jiangnan for the incident in the Jiangnan Town of Tianfu.
Jiangnan said indifferently: "Auntie Color, you don't need to apologize. It is normal for the project to be failed. Moreover, we did not suffer any losses from Changying Real Estate. We did not have enough manpower to Tianfu to form Changying Real Estate. Now the project has not been completed. Now the Jiangnan town in Tianfu cannot be completed, which actually reduces the burden on us. When the time is right in the future, we will come to Tianfu again."
Yan Yujun said, "Jiangnan, every time I see your aunt, I feel very moved. We and your father have not seen each other for many years. The first time we met you in Xiaochuan. At that time, you were in the third year of high school, and now you are in the second year of high school. You are still busy with big and small things in your company. When I saw my daughter Jinyun and Jinpei, who are only in the sixth grade, I feel that they are half a generation away from you."
Professor Luo smiled and said, "This is incomparable. We met later and got married later. Look, Jiangnan is now engaged before graduation. I even think that with his relationship with General Xiaoyue, he can get married after graduating from university and reaching the legal age. In this case, it may be a whole generation different from our family in the future."
Yan Yujun said: "Jiangnan, did your dad tell you why he got engaged to you so early?"
Jiangnan thought about it and it was not suitable to tell Aunt Yan Yujun about the matter of Hua Lianyue's family, so he said, "I think it may be because my mother has a lot of factors, because my mother proposed the engagement first. Maybe my mother thinks that our relationship has always been stable, and she also likes Hua Lianyue very much. In addition, Hua Lianyue goes to school in the Demon City and usually lives in our Demon City house. Maybe it's more convenient to live there after getting engaged."
This is what Jiangnan thought of to the outside world.
Yan Yujun thought for a while and said, "There is a certain reason, but we still find it incredible, because even if you two are not engaged now, it will not affect your future marriage, and vice versa. Therefore, there seems to be no need to get engaged now. Of course, only your father can understand this problem best."
Professor Luo said: "Every family has a difficult sutra, maybe Jiang always has his own considerations."
Yan Yujun said: "Then what do you think Jiang Dongping is thinking?"
Professor Luo smiled and said, "Maybe I'm wrong, but I think it's almost the same. Maybe you didn't notice that Jiangnan is a college student from Tsinghua University and Peking University, and now he is in charge of his family's business. Jiangdongping also has some friends with equal status in the business world. However, in general, in wealthy business families, there may not be many daughters who are better than Hua Lianyue. Jiangnan is about to graduate in two years, so can you understand what I say?"
This explanation seems to make some sense.
Jiang Nan said: "Uncle Luo, I really don't know about this. Because the engagement was the day before New Year's Day this year, when my father returned to his hometown in southern Gannan, my mother suddenly mentioned it. Maybe my father listened to my mother's opinion and combined with this consideration, so he agreed."
