Through the new research methods, this thesis has made the following contributions in this field: 1. For the first time the curvature radii and relative angles of a planar continuous curve at discrete points are chosen as local parameters to represent the curve, which reflect clearly the local geometrical characteristics of the curve and are easy to be dealt with.

借助于新的研究方法很操亚洲美女，本文在這一領(lǐng)域作出如下貢獻(xiàn)：（1）首次提出用曲線上離散點(diǎn)處曲率半徑和相對(duì)轉(zhuǎn)角作為局部參數(shù)表示平面連續(xù)曲線，直觀地反映曲線各個(gè)局部的幾何特征免费看黄的视频网站，且便于曲線的修改和變換欧美一级A片裸体视频，并通過(guò)機(jī)構(gòu)運(yùn)動(dòng)分析，快速求出機(jī)構(gòu)軌跡的這兩個(gè)局部參數(shù)国模一区二区三区私拍视频大胆。

The depth of central-axis percent dose Rx (except R100) and practical range, Rp, for small field electron beams can be calculated by the proposed empirical formula: Rx = Rxo ×,where Rxo R po are the broad beam percentage dose depth and practical range respectively; r is the small field cutout side when it is less than the maximum lateral scatter equivalent range, and m is he exponent term relative to the decreasing curvature.

Several representations of numerical simulation, such as induced curvature, the conditions of first—type limit, second—type limit and singular solution, are presented under continuous and differential conditions. A new system of numerical simulation, which is relative as well as independent to traditional theory, is established.
