The nonlinear Winkler-Kelvin sub-grade model is adopted in this simplified model and the complicated 3-D problems of the soil-single piles dynamic interaction are simplified to the 1-D, that is to say, the lateral nonlinear acting force of the soil to the pile shift is simulated with thehorizontal nonlinear springs which have the continuous uniform distribution, while the nonlinear spring restoring force is described by the deteriorated Bouc-Wen model; the radiation damping and material damping due to the energy dissipation and inner friction in the soil are displayed with the dashpots which are in parallel with the horizontal nonlinear springs.

There was no evident change in the atropine group; the axial length was obvious prolonged in tropicamide group and control group.(3) The phengophobia symptom. In the initial stages the two treatment groups had difference symptom; after 2 month later the symptom was mostly dismissed.

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。

Yuan Zhesheng's fiction often recounts family and father-son stories. His most celebrated feature is his speculation on time. Imaginative games in enclosed space also turn up frequently in his writings. Therefore, a research framework consists of time, space and human world is a criterion that delineates a fictionist's image of mind in three-dimensions.

袁哲生写得最多的是家庭、父子小说，最为文坛知悉的是时间的思索，最常出现的场景是闭锁空间的游戏想像，因此时间、空间、人间三向轴的研究架构，是为立体化小说家创作心象所设的凖的。

This design wants to design a complete set of three axes five speed gearboxeses , it mainly include three parts : The first part , to make sure the basic parameter of the gearbox assurance ; The second part, The contact strength verify-check and the flection strength verify-check of each wheel gear of the gearbox, mainly verify whether each wheel gear satisfy various strength conditions with according to the giving parameter ; The third part , to progress verify-check intension of the axes Four-part cent, to calculate the life of the bearings.
