The electronic structure of the primary electron donor D - 2A and other pigments in photosynthetic reaction center (RC) of the mutant HM202L of Rhodobacter sphaeroides has been studied with the ab initio DFT method.

The electronic structure of protein chains L and M in photosynthetic reaction center (PRC) of Rhodobacter sphaeroides (Van Niel) Imhoff, Truper et Pfennig) was studied by using the Overlapping Dimer Approximation method and the Extended Negative Factor Counter method at ab initio level.

The ultrafast energy transfer process, which takes place in femtosecond time range, in bacterial photosynthetic reaction center RS601 was investigated using femtosecond pump probe technique with selective excitation.

The results showed that the forages could overcompensated the feeding by the grasshoppers of low instars,with forage yield increased,higher in field caging than in artificial simulation.

In this paper,the breakdown characteristics were studied through artificial simulation test,and the relationships among breakdown voltage and some factors,such as rain intensity,rainwater resistivity,and drop direction were investigated,and the corresponding results were obtained.
