The relation of the surface shape error to f-number and relevant spherical radius was achieved according to the reducing analysis model ignoring the local f-number. Two kinds of rhombic prism model are established by ZEMAX. According to the simulation results from ZEMAX, the correctness and limitation of the former methods are proved and analyzed. The results are used to analyze the effect of the surface shape error of the rhombic prism on parallelism of the emergent beam. The assignation plan of the surface shape error for each working surface is presented.

根据忽略局部光圈数的简化分析模型，获得面形误差对应光圈数与相关球面半径的关系，通过几何处理方法，求得一定面形误差对应的球面半径与平面倾角的关系，将斜方棱镜的工作面倾斜一定角度，运用折射定理，将具体面形误差转化为相应平面的倾斜角度，得到出射光相对于理想光轴的倾斜角度及其关系式，并在ZEMAX中建立斜方棱镜的两种模型。

合方治疗脑缺血24小时组缺血脑组织nNos光密度值较缺血24小时模型组明显降低（p＜0.01）。细胞的死亡分为坏死和凋亡两种方式，凋亡是细胞为避免对机体造成更大损伤而采取的一种程序性的死亡方式。珍珠母、胆酸、栀子苷、黄芩苷、合方治疗组较脑缺血24小时模型组可明显降低P53阳性表达，考虑药物抑制细胞凋亡可以起到对缺血脑组织的保护作用。

So karst vegetation is charactered by Petrophile, Xerophile and Calciphihe in those areas where soil cover is very thin, and the underground drainage system is well developed. The running of karst ecosystem is controlled by two subsystems, which are karst dynamic system in inorganic life and genetic information transmitting system in organic life.
