In this paper, according to the basic principle of light– ray propagation, the elliptic cylinder lenses have been designed and used to collimate the semiconductor laser beam. With the computer simulation by use of Matlab, the numerical results are given. The numerical results indicate that the divergence angle of the collimating beam could be as high as 0.1mrad.

在本文中，针对现在对半导体激光器准直的要求作者基于利用柱透镜对半导体激光器光束准直的理论分析，设计了利用椭圆面柱透镜对半导体激光器进行光束准直的方案，对半导体激光器发出的光束经过椭圆面柱透镜的光路进行计算，并且利用Matlab对方程进行求解及计算机模拟得到最终结果。

By using two groups of cylindrical lenses perpendicular to each other, the marking shape window of semiconductor laser is imaged and rectangle and this imagery is then collimate d to infinite by collimating objective.

利用互相垂直的两组圆柱面镜把半导体激光器的条形窗口成像为矩形。再用球面准直物镜组把此象"准直"到"无限远"。该系统把激光器发出的发散光束压缩到在±0.0025弧度内出射光。两组柱面镜的同种倍率互为倒

The extended Poincare map in this paper needs twosurfaces of sections transversal to the flow in phase space,i.e.,relates the crossing of a plane containing one of the collinear libration points back to the periapsis passage.Meanwhile,the map is calculated numerically using the Total-Variation-Diminishing Runge-Kutta integration method to get a good description of the Poincare sections.

文中的推广的Poincare映射需要在相空间中选取两个与流相截的面，即将包含某个天平动点的截面通过轨道来映射到近拱点的通道面上的，在数值上通过总变差减小的Runge-Kutta方法来实现两个相面之间的映射。

In this paper, the major factors which have effects on the numerical convergence includ the inner distance of the sources submersed into the body surface, the distance moved upward above the mean free-surface, the computing range of free surface, and the collocation point interval.

本文选取足够的自由面计算范围和边界配置点数量，讨论了物面内潜深度和自由面上提升高度对计算结果收敛的影响，并建议了内潜距离的计算表达式，获得了一致收敛的数值解。

This method overcome the problems of many supposition conditions in theory and difficulty in searching critical slip surface in 3D limiting equilibrium analysis; It uses the 3D FEM\'s stress field directly, differs from the practical value of 3D FEM strength reduction method used hypothesized load, and differs from the characteristic of the FEM with limiting equilibrium theory still to need to divide the columniation, and suppose the critical slip surface in advance.

该方法克服了三维极限平衡分析方法在理论上引入较多假设条件，且搜索临界滑裂面困难的问题；它直接采用三维有限元应力场，不同于三维有限元强度折减法基于虚拟荷载上得出的实用价值；同时异于沿用极限平衡理论的有限元法仍需要进行条柱划分，并事先假设滑裂面形状及位置的缺点。

In addition, depending on the method of numerical simulation and theoretical analyses, some kinematic and geometric features of 0° involute—enveloping worm gear drive, such as meshing surface, first—type limit, second —type limit, worm surface, the numerical representation of contact line and bearing contact, are systematically studied. These relevant conclusions provide an important basis for the design and manufacture of new type worm gear set. As we predict, the method of numerical simulation has special effect in solving the question of complex conjugate surface.

With a mature skin you should not use the general adolescent acne application dedicated Face, because those in the cleaning composition Face degreasing and disinfection power is too strong, for adults but can cause skin damage, making acne worse.

具有成熟肌肤的你最好不要使用一般青春期适用的面疱专用洗面乳，因为那些洗面乳中的洗净成分脱脂及杀菌力太强，对于成人肌肤反而会造成伤害，使面疱更加恶化。
