Based on data cloud, which is measured from 3-coordinate measuring machine or so, an algorithm to search lopological structure from 3D unorganized points using Envelopment-box technology is proposed in this thesis. Based on this method, we searching neighbor points of sampling point. We also improve the Max-Min angle criteria to realize local triangulation, and then get the normal of sampling point from the triangulation. Using the normal and neighbor relationship, classification of scattered data points is realized according to the quadric surface.

本文以测量得到的曲面数据点点云为基础，提出了一种基于包围盒的自动寻找三维散乱数据点之间拓扑结构的方法，采用该方法寻找采样点的邻域结点，并对三角剖分中的典型优化准则—最小内角最大准则提出了改进，按照改进后的优化准则实现了采样点的局部三角划分，并进一步求解得到采样点的法向量，依据法向量及邻域拓扑关系在二次曲面的基础上实现了散乱数据曲面重构中的数据点的自动分类。

The first one is to generate the circle for each borderline segment of the component by considering the segment length and the prescribed tolerance value. If this is not the case, the borderline segment will be equally divided into halves until the obtained circle satisfies the tolerance value over the whole borderlines of the component. The basic idea of the last two algorithms aims at covering the domain occupied by the component as much as possible. The circle generation is carried out sequentially from salient angle to the sector formed by the salient angle till the uncovered borderline segments of the component. Particularly, the three-step algorithm with gap allows that the generated circles are distributed with gap along the component contour.

二分法利用组件各边长度和设置的容差大小得到该边的候选包络圆，若该圆不满足组件所有边的容差要求，则将该边不断地对分，直至所得到的包络圆满足各边的容差要求；三步划分法和带间隙的改进三步划分法则以组件区域为划分对象，依次对组件多边形凸顶角、凸扇形区和多边形各边剩余线段划分包络圆，且带间隙的改进三步划分法则允许包络圆在组件边界上以适当的间隙分布。

The authors discuss a new numerical simulation method of the downburst wind loads on the basis of the previous research. Firstly, the wind speed is expressed as the sum of an instantaneous mean wind speed and an amplitude-modulating non-stationary fluctuating wind speed. Secondly, a new method based on the modified Osegguera and Bowles/Vicroy model to simulate the mean wind is presented and the fluctuating wind is simulated by a modified spectral representation method.

在将下击暴流风速表达为时变的平均风速和调制的非平稳脉动风速之和的前提下，本文采用基于改进的OBV模型Oseguera and Bowles/Vi-croy(OBV的方法来模拟平均风速，其平均风速直接由改进的OBV模型表达，而不同于已往研究中将平均风速表达为竖向风剖面与时间函数的乘积，并采用结合快速傅里叶变化的谐波叠加法来模拟调制的非平稳脉动风速。

In the end, the essay analyzes the operation result of the above proposal and puts forword with suggestions and comments on a stepped-up improvement.

最后，本文对该改进方案在一定时期内的运行效果进行分析评价并提出了进一步改进意见。

I build my research work on the pass and improved the hardware and software of experimental system, and explored some new analyzing methods to pick out the CEP signal wrapped in the EEG more efficiently.On hardware, I designed a instrument to let our testee to observe the RDS, shown on Cathode-ray tube or printed on paper, through a stereoscope, and never let the stereoscope effect the observation. The instrument includes 3 modules: RDS showing, stereoscope fixing and testee fitting.
