On the basis of this model, a set of rate equation was established. Analysis of its algebra solution led to a general picture of energy transfer process in LHC Ⅱ of higher plants and the strong interaction among pigment molecules in this process. Based on the spectra, kinetics and biological structural data providing some information of energy transfer path and energy dissipation mechanism, it has been found that energy transfer mainly happened between the pigments whose energy level was most closely adjacent, the loss of energy had a close relation to the process of energy transfer and tended to increase with the decrease of energy level. The protective mechanism of antenna system was also discussed.展开更多

We put forward the framework of the four level practical teaching system, and explore the practical scheme of the system in computer application technology. There is a big gap between the employment of graduates and the social demand, which is a common problem in higher vocational colleges. In order to cultivate technical talents in social and economic development, according to the existing practice of higher vocational education in the teaching of hardware is not sufficient, system construction is not complete and other problems, this paper explores the people-oriented, with three dimensions of skill dimension, technology literacy and dimension, with training room, training center, training base, training base four layer structure.展开更多
