I've heard many sayings that I'm not happy reading blogs, and I've also heard many worthless suggestions. But I still stick to my own idea, and the idea of taking the initiative to take the doctoral exam in those years can still be used for reference for those who want to take the doctoral exam. I don't encourage others to take the exam, but it's ok to put forward my own experience. I just watched the doctoral enrollment of computer science and technology in 2004. There are 206 applicants and 35 students enrolled. This ratio is really terrible. I applied for computer science and technology cross-major, public-funded study. I majored in mechanical electronics, from XX University, majoring in advanced manufacturing technology and fault diagnosis of mechanical manufacturing and automation, with a master's degree. Actually, I have no advantage at all. I should be able to say that all I can do is rely on my own strength. I never thought that I would fail in the exam or ask for other people's opinions, because I know that other people's suggestions must only represent his personal views and what he wants to do, so why ask for other people's opinions? Doing things is two steps: 1, do it when you think about it, and 2, do it well and achieve your own requirements (also called success). That's how I started reviewing. I spent three months preparing for the exam. To tell the truth, I didn't take any courses before applying for the exam. I chose the principle of database and the basis of computer graphics algorithm. Just because I haven't taken these classes doesn't mean I don't understand these knowledge. I carefully consulted the textbooks in Wang Nengbin's database, and then compared all the related textbooks. After thinking over all the knowledge and differences. Especially computer graphics, I have read the assigned textbook six times, but in fact it may reach eight times. Some students will definitely ask: you can't watch it so many times at all, and I can't explain this question well. But it's true. I have read the monograph written by my tutor, which should be three times (in fact, many of them didn't understand). I have read the graphics book written by Zhejiang University. For example, I have read everything I can (I thought it was fun to read before the exam, but I didn't read a master's degree at that time), but there are not many well-written books. Of course, I don't deny the weight of other books. Among them, Sun and Computer Graphics Algorithm Basis have many mistakes (most of them are but the reading process is painful. If you are not interested, mine. I am a person who follows the plan strictly, at least in recent years. I have my own plan every day and finish my work on time every day. My life is very simple, that is, get up, finish the plan, make a plan, sleep and stick to it for three years. Of course, I lost a lot. I once published an article in the doctoral edition, which was regarded as. I just gave a wry smile. Actually, it's your own business. Why impose it on others? As long as you prove it is correct, do it well. The article I published is: the power of habit. It is said that I get up and do 50 push-ups every day, which is regarded as a joke. Actually, this is not a joke. I have been doing it for almost 10 years, and it has become my habit. I'm interdisciplinary because I hate this major. I took my master's degree that year: Huazhong University of Science and Technology. Later I transferred to Guangxi University for an interview. None of the teachers want me. An academic leader of mechatronics asked me three questions, but I couldn't answer them. He felt very strange and asked me. Isn't it for circuit control? Why can't you answer? I wonder in my heart, too. I have done circuit control, but my results are good, but you are asking about things in books, not practical applications? Then why don't you ask me if I can speak C and C++ can program? Don't ask me what I did. I was really stupid at that time, but I didn't explain,,, and the interview was over. The School of Mechanical Engineering of Guangxi University didn't recruit people. I went to graduate school. Let me explain here that I didn't belittle my alma mater, just said the actual situation. So, I was admitted to the doctor, and the tutor didn't give me the scope. Of course, what really supports me is my interest in computer programming and this industry. My hobby has been in this direction for many years. I used to work 16 hours a day and write two modules for three months, and I was as happy as all my colleagues who liked programming. In these aspects, within my limited scope, I am really excellent. I like what I do and I like this major, so I am interdisciplinary. I am very grateful to my doctoral supervisor here. I don't deny that I am excellent in some aspects, nor do I deny that I am poor in some aspects. I don't shy away and give full play to my advantages. I also firmly believe that habits can achieve the future, and the future is chaotic, which only represents personal views and does not impose anyone. Of course, my personal views are limited, and criticism and correction are welcome. I know it's hard to study for a doctorate, and it will be difficult to graduate in the future, but it's normal, because everything is a matter of choice. A few years later, no one knows who it is. -
