Today, it is an indispensable key discipline in the high-tech field. For example, it is the great progress of electronic technology that promotes the arrival of the information age based on computer network and will change the life and work mode of human beings. In a sense, the degree of development of electrical engineering represents the level of scientific and technological progress of the country. Because of this, the education and scientific research of electrical engineering has always occupied a very important position in universities in developed countries. Among the institutional names of electrical engineering in American universities, some schools are called the Department of Electrical Engineering, some are called the Department of Electrical Engineering and Information Science, and some are called the Department of Electrical Engineering and Computer Science. This discipline (department) is very different from the domestic electrical engineering discipline in scientific research, teaching and academic organization. Understanding the situation of foreign disciplines and the direction of teaching and research plays a very important role in adjusting the direction of disciplines and improving the level of teaching and research. Traditionally, electrical engineering has been defined as the sum of related disciplines used to create and produce electrical and electronic systems. This definition is very broad, but with the rapid development of science and technology, the concept of electrical engineering in 2 1 century has gone far beyond the above definition. Professor Stanford University pointed out that today's electrical engineering covers almost all engineering behaviors related to electrons and photons. The huge growth of knowledge in this field requires us to re-examine and even reconstruct the subject direction, curriculum and content of electrical engineering, so that the subject of electrical engineering can effectively respond to the needs of students, the needs of society, the progress of science and technology and the dynamic research environment. The main factors that will have the greatest influence on the development of electrical engineering in the next few years include: 1, the decisive influence of information technology. Information technology is broadly defined as including computer and global high-speed broadband electrical engineering legend.
Computer network and communication system, as well as the synthesis of related supporting technologies for sensing, processing, storing and displaying various information. Information technology has a particularly significant impact on the development of electrical engineering. The continuous exponential growth of information technology depends largely on the continuous technological innovation of many disciplines of electrical engineering. Conversely, the progress of information technology provides a newer and more advanced tool base for technological innovation in the field of electrical engineering. 2. Broaden the intersection with physical science. Due to the invention of triode and the development of large-scale integrated circuit manufacturing technology, solid-state electronics played a great role in promoting the growth of electrical engineering in the second half of the 20th century. The close connection and intersection between electrical engineering and physical science is still the key of electrical engineering discipline in the future, and it will be extended to biological systems, photonics and micro-electromechanical systems (MEMS). Some of the most important new devices, systems and technologies in 2 1 century will come from the above fields. 3. rapid change. The rapid progress of technology and the rapid development of analysis methods and design methods make it necessary for us to reflect or review the past methods to solve engineering problems every few years. This has a great influence on how to hire new professors and how to train our students. Electricity is an important material basis for developing production and improving people's living standards. The application of electric power is deepening and developing, and the application of electrical automation and electrical engineering.
Modernization is an important symbol of the modernization of national economy and people's life. As far as the current international level is concerned, the demand for electricity will continue to grow for a long time to come, and the demand for electrical engineering and automation science and technology workers in society is on the rise. Electrical automation is used in industrial control systems. For example, how can a device run to ensure the normal production of qualified products? Modern industry is not entirely handmade, but made by machines. When the machines are started, they will run automatically. The reason why the machine can run automatically is electrical automation. The so-called electrical automation is the process of realizing sequence control and time control by using electrical components such as relays and sensors. Others, such as some instruments or servo motors, can be fed back to the inside according to the change of external environment, thus changing the output and achieving the purpose of stability.
This century is the century of life science. As medicine, the long-term task is to prevent and treat diseases. However, from now on, the main task of medicine will be to maintain and enhance people's health and improve people's quality of life. In this range, medicine used to face patients, but now medicine will face all the people. In the past, medicine was in hospitals, but now in Europe and North America, half of doctors have left hospitals. They live with ordinary people in the community, guiding them in health care and medical treatment, and more importantly, guiding people there how to live correctly. Today, there are 97% doctors in hospitals in our country. With the development of the times, doctors will gradually go to the society and enter the crowd. In this sense, the allocation of doctor resources in China is bound to change. At present, there is no concept in China, that is, fast green passage to emergency room. It is absolutely necessary to establish a fast and green emergency passage. The concept of convenient medical treatment is the future direction. Many countries have begun to implement brain death laws. After brain death, organs, tissues and cells are still alive due to the support of circulation. If the deceased had a good style before his death and offered to donate his organs to others, he could have a kidney and liver transplant. After the human genome is basically completed, it will have a great impact on medicine and will have a deeper impact. Many genetic diseases can also be prevented by improving life and environment. Drugs are compounds. In the near future, drugs are not only compounds, but also protein, genes, cells and even some tissues and organs. Because of this, in the future drug trials, pharmacology, toxicology and clinic are no longer the first to be examined, but ethics is the first, and everything must be examined ethically first. Why are you talking about this? Because, if genes are to become drugs, or tissues and organs will become drugs in the future, they should be allowed first. Learning the introduction of life science can help us better understand ourselves, master the similarities and differences of life, and solve the wonderful life phenomena that people have been paying attention to, observing and studying. Life science is a profound and complex subject, which can be seen from the classification of life science, but its learning process is very interesting and it is so close to our daily life! We are doing exactly the same thing and living exactly the same life every day, but I didn't know it was not that simple until I finished reading Introduction to Life Science. It has inspired me a lot, not only in life science, but also in medicine, science and technology, agriculture and so on. As the teacher said, "there is a high degree of communication and intersection between sciences." This subject reminds me of the common sense of chemistry, physics and biology in middle school, connecting my fragmentary knowledge into a line, making my thinking clearer and my knowledge more orderly. It is the essence of my six-year summary of junior high school and senior high school. A lot of pictures are quoted in the course, which is completely different from the previous class. Although what the teacher said in the previous class is roughly the same as what the teacher said in this course now, I just listened before. It seems that there is a distant feeling for all scientific knowledge and scientific and technological achievements, and it is a bit incredible for its authenticity. However, with the confirmation of the pictures, in addition to increasing the activity and learning atmosphere in the classroom, I have a further understanding of this knowledge. I used to have a very one-sided understanding of genetics, but now I know that there are many kinds of genetic diseases. Many of these names have been heard before, but I don't know what happened before. Sometimes I saw such an example in the street, but I didn't know it was a genetic disease. Even if I do, I don't know what this genetic disease is called. Now, after the explanation in class and pictures, I have a further understanding of this, which is very helpful for reading newspapers, watching TV or reading extracurricular books in daily life. It is even helpful for my English study, because I have a preliminary background knowledge in this field, and I can read English articles more easily. The recent re-election of American President George Bush has deepened the contradiction between God's creationism and Darwin's theory of evolution. When this theory was first put forward, it was criticized by all sides because it completely denied the "creationism of God". For centuries before Darwin was born, people believed. The bible? Every part of the library. Are you online? The bible? The book describes in detail how God created man and the earth. It says that the earth and all living things were created by God in six days, and every living thing was independently created by God. But in the middle of19th century, Darwin's theory profoundly changed the deep-rooted concept of human beings and greatly shook the whole world. Recently, this theory has caused another storm. In the west, most people are strongly opposed to writing "evolution" into textbooks. When it comes to biology, only a few countries allow it to be taught. A few people think that both theories should be taught, and only a few people insist. I think these two subjects can coexist, both theories should be taught, and students should choose and develop their own unique concepts, ideas and explanations. Let's talk about Calvin's "evolution theory", which is of great significance to biology. He urged people to study morphology, paleontology and embryology. On the other hand, "God's Creationism" has a profound cultural background and has a great influence on European culture. At that time, many paintings, music and literary works were related to religion. ? The bible? It is a model of literary works. Many famous English novelists' words come from? The bible? In middle school, it is the crystallization of literary works and a must-read book for English learners. This course broadens my horizons and consolidates my knowledge. It is the result of the former's hard research, continuous discovery and revision, and gradual confirmation and affirmation for more than three years and almost four centuries. It is the cornerstone of mankind's achievements in medicine, science and technology and agriculture, and an important step in the development of the country and society.
