Discussion and Practice of Blended Teaching in Basic Theory and Application of GSM-R

In order to accommodate the trend of high-speed railway signaling integrating with communication techniques, Basic Theory and Application of GSM-R is a crucial curriculum for students majoring in Traffic Information Engineering and Control and Transportation Engineering. It helps students to master the latest theory and application of train-ground communication techniques. However, with the application of the next generation railway mobile communication technique, several advanced communication techniques are presented in the form of English materials. It is of great significance to have a bilingual teaching mode for this course. This would contribute to cultivating research-oriented and professional talents with international competitiveness. Through the blended teaching reform of bilingual education, the proportion of topic selection of interdisciplinary research papers by postgraduates has increased from 6% to 15%. In this article, the characteristics and the current problems of bilingual teaching are discussed from theory to practice in three aspects: the production of bilingual courseware, the supplement of English materials, and the guidance of research topics. Additionally, corresponding teaching reform schemes are proposed in this article.

The basic theory of bipolars existence and their role in the examination of electric and magnetic fields

This article claims that the universe is composed of very fine particles, which are billions of times smaller than electrons. These particles consist of one positive pole and one negative pole similar to protons and electrons (in terms of electrical charge), respectively. They are point electric charges, which their movements and bending of their chain in space create magnetic fields and electromagnetic waves. These particles possess mass that verges on zero, due to their minute size. Then, by examining several physical phenomena, the presence of them will be proved.
