EAE evidence collection record (2)

Wang Jiudong, General Manager of Datai Technology

The sixth batch of students of Yifa EAE

Fortunately, there is also Mr. Li, who is one year younger than me, among my classmates. Finally, I have a classmate of the same age who can advance and retreat together! At first, I talked about bonding and the advantages and disadvantages of bonding. Fortunately, they were all things I knew. However, the following thermodynamics such as chemical bonding, enthalpy, and entropy made me confused as I had only studied "General Chemistry" 39 years ago. Confused, I can only bite the bullet and remember it, but I really can’t remember it! It was a strict closed-book exam (the invigilator, Dr. Yu, was very serious...). After handing in the exam, I hurried back to Tangshan. I couldn't let go. Fortunately, a week later, a message came from the WeChat group: "Everyone has passed." I can finally rest assured. .

In the second week of September, I transferred to Changzhou to study, another base of Yifa. This week I started to talk about "adhesives".

Although I am familiar with the epoxy resin glue, silicone glue, polyurethane glue, methacrylate glue, anaerobic glue, etc. that I have often used for many years, the curing mechanism, reaction form, etc. are very vague. One week is worth thirty years. This is a sublimation and qualitative change in how I choose glue and scientific construction in the future! Maybe it’s because I’m familiar with it and willing to learn. I’m no longer worried about the exam this week, knowing that my results will be good.

In the third week, we talked about surface treatment, which is also something I really want to learn. Although some of the basics are not easy to understand, I am still quite confident.

In the fourth week, we were taught remotely by Germans. Due to the different cultural habits and ways of thinking, I felt conflicted during the class this week. I basically didn’t understand it and barely passed the exam. It wasn't until the review in the eighth week that I fully understood the methodology of this joint design. Once I understood it, I knew the importance of this. At the same time, I also felt the gap between us and the Germans in the epistemology and methodology of natural science. Not just in the natural sciences, just take a quick look at "Das Kapital". In the humanities, including Marx, the ancestor of communism, he not only has a completely logical and quantitative approach to problems, but is also very good at using formulas to calculate. I just don't know what Marx means. Did our ancestors use mathematical models and finite element analysis at that time?

The next week became more and more relaxed, especially the safety class taught by the beautiful teacher. Not only did they easily learn the safety and environmental protection knowledge of adhesive construction, the young students also learned how to get along with children, and also learned parent-child education. It was really unexpected. What a harvest!

In the sixth week, I caught up with the epidemic in Hebei, took a nucleic acid test, and came to Shanghai. When I entered Shanghai, I didn’t feel the fear of people from Hebei in Shanghai. Instead, the course organized a visit to a famous rubber factory. This ghost guy’s It doesn't matter if the company doesn't let people from Hebei go. I have been to Shanghai several times in the past six months and have been studying. The Qibao Ancient Town next to it is very famous. Everyone went to visit the rubber factory. I walked around the ancient town for a few hours, tasting fried stinky tofu, and went to several famous restaurants. Tasteful used bookstores are still very rewarding.
