Based on moving least squares surface, the differential properties of each sample point on PSO are first evaluated. In terms of covariance analysis, the elliptical splat of sample point is then determined on its tangent plane. Finally, the splats are rendered from far to near by using elliptical weighted average filtering. According to the differential properties, moreover, the suggestive contours of PSG are attained so that non-photorealistic rendering of PSG is realized.

首先根据构造的移动最小二乘曲面计算采样点的表面几何属性，然后根据协方差分析确定点元在其切平面上的椭圆表示，最后采用椭圆加权平均滤波从远到近单遍绘制各点元，此外，根据表面几何属性确定点模型的轮廓线，实现了点模型的非真实感绘制。

Based on the wheel/rail multi-point contact in turnout zone, a dynamic design theory for high-speed railway turnout was established and several creative designs were made, such as separated semi-tangent switch plane linetype, horizontal hidden nose structure of turnout frog, short transitional top surface figure of the switch rail, and track stiffness of turnout with even elasticity.

基于道岔轮轨多点接触关系，建立了高速道岔动力分析理论，并设计出适合我国高速道岔的相离式半切尖轨平面线型、心轨水平藏尖结构、尖轨短过渡顶面轮廓和弹性均匀的岔区轨道刚度。

A gear H62 which made in yellow brass with the same mode number m=0.34, 2mm thick and had a center hole, when the gap get C=0.5%t , and punched with compound punching die, and the dimension accuracy reached IT7, the part have a flat surface ,the verticality of tangent plane reached 89.5°, its roughness Ra magnitude are 12.5μm, height of burr are 0.10mm; and the punching part are punched with progressive die, the gap C=7%t , initial accuracy are IT11, and have an more rough surface, even can see the gap with eyes.
