The origin for ＂the tight vector can be expressed by electricity vector under the normal case＂ in op- tical textbooks is discussed. The analysis shows that the optical rotation phenomena and the light vector of negative refractive index media can not be expressed fully by the electricity vector. We still point out that the basic connotation of the concept shauld be developed with the development of the discipline.

the wave functions of （nd）^3 electron configuration for LS coupling is discussed by using the second quantization from the Pauli exclusion principle, anti-symmetric wave functions for fermion and symmetry of raising operator and lowering operator. It is pointed out that the （nd）^3 electron configuration can be formed two different 2D wave functions.

We extend a simple exercise in a textbook and find rich physical information by studying nonlinear effect of the system under consideration. The non-typical beat phenomenon and the abrupt change in tension are the most noteworthy results. We analyze these results, investigate the factors that lead to them and point out the drawbacks of the original model through simulating calculations.

＂Guide to Astronomy＂ is a professionally basal course for lower undergraduate students in the department of astronomy and for upper-class ones in the department of physics of Beijing Normal University to study general and systematic knowledge and some progress on astronomy. As a national top quality course, the innovation has been made in teaching contents and methods and the sparkling teaching achievement has also been produced during the recent years. However, the perfect evaluation system on study and examination associated with them is not build. According to small class in department of astronomy and large one in department of physics, some present contents and methods of evaluation system on study and examination are respectively introduced. In addition, the teaching assumptions are designed to continue to build the evaluation system during the application of teaching.

Astronomy is a discipline based on observations. Trairring of talents in astronomy and public education in astronomy pose various requests to astronmrucal practice teaching. For recent years, Department of Astronomy of Beijing Normal Universily has built multi-level of practice platform for astronomical teaching,providing targeted practice teaching conditions for professional and non-professional, undergraduate and graduate students. New explorations and attempts have been carried out in practice aspects of training of high-quality astronomical talents and teaching of high-quality astronomical public courses. A number of innovative achievements in education and teaching have been obtained which are worth of application and popularization.

Astronomy is a discipline based on observations. The development of modern astronomy, highlighting the importance of astronomical observations in the major discoveries, puts forward higher requirements on astronomical talent. Currently, practice teaching is regarded as one of the most important aspects in undergraduate teaching by all of the departments of astronomy in Chinese colleges and universities. Practice teaching resources show explosive growth in types and quantities with the growing number of inputs for practice teaching, as well as the rapid development of computer, networking and multimedia technology. Tbis article, taking the construction of practice teaching dagital resource library in the department of astronomy in Beijing Normal University for example, explores the systematicness, rationality and sharing of the practice teaching integration.
