Automatic control theory is the core course of electrical engineering and electronic information engineering, which directly influences the learning of specialized course and the cultivation of ability to analyze and solve problems. In view of the existing knowledge dispersion of existing textbooks content and the lack of correlations between the knowledge structures, from the viewpoint of establishing the control system model, taking mathematic model as the foundation, curriculum of automatic control theory is divided into the control system analysis and tuning of control system, to organize the teaching system of automatic control theory. Combining with the teaching content, the teaching method and evaluation system of course were improved.

Based on the survey result of teaching quality,the problems in teaching target,teaching mode,and teaching method of traditional teaching of professional basic experiment were summarized and analyzed. It is proposed to solve these problems by establishing double-leveled teaching target,adopting the teaching mode of "expanding teaching before and after class",and teaching in class by methods of introduction,stimulating thinking,case analysis,guidance and exchange. The teaching reform and experience was applied on the professional basic experiments of professional course of Drilling Engineering. As a result,the students' learning enthusiasm and learning interest are greatly raised and motivated. The teaching quality is significantly improved.

Because primary radar plays an important role in averting flight conflict between civil aviation and military aviation, some internal airports installed primary/secondary radars. Some air traffic control primary radars use pulse compression technique. The biggest advantage of it is the increasing radar range and improving range resolution. This paper introduces conception of Linear Frequency Modulation (LFM)and pulse compression, analyzes the frequency spectrum and pulse compression principle, summarizes the advantages of pulse compression technique and gives an application model.

This paper provided a preparation and measurement platform of energy storage materials, and described the working principle of the experiment station. Based on the experiment platform, we can microscopically observe the crystallization process of the sample under ultrasonic or not, and analyze the temperature of the sample during cooling process. It is found that ultrasonic can reduce the degree of supercooling of water, make the supercooled water formation of crystal nucleus in advance, shorten the freezing time of samples. The experiment results show that ultrasonic can not only lower the crystallization degree of supercooling of water, but also effectively refine the grain size.
