poiseuille的LBM模拟，C++，三种边界处理方法。周期、反弹、曲线。(LBM simulation poiseuille s, C++, three border approach. Cycle, rebound, curve.)

cad中可以像cass一样划线,具有换向，隔点闭合等功能！(cad cass huaxian)

cdma2000的下行连路仿真模块matlab模块 推荐一次(Cdma2000 downward even road simulation module recommend a matlab modules)

直接将坐标展在cad中和南方cass中的一功能相似，只是直接在cad中就直接能实现该功能。(Directly coordinate the event in cad and in the South cass of a function similar to, but directly in the cad on directly to achieve this feature.)

绘画出三阶的贝塞尔曲线, 求出曲线上各点的曲率和半径,可用于弯道设计(Drawing out the order of the Bezier curve, find the points on the curve and radius of curvature, can be used for curve design)

一款用vc++编写的画图软件，本软件提供了画一些基本图形的功能，还有将图形进行填充。(vc with one prepared by the drawing software, the software provides a graphic pictures of some of the basic functions, there will be graphics for filling.)

本文以电场的三大定理、连续超张弛迭代算法、拉格朗日插值算法等原理知识作为理论基础，以 C 语言为编程工具，将由根据以上物理和数学原理所推导出来的模型转化为可以计算像管内电势的 CAD 程序软件。所编写的程序可以在给定像管参数和电极电位的情况下，计算圆柱形像管内任意一点的电位大小，并绘制出像管内的等势线；拉格朗日插值得到对称轴上任一点的电位值。 (In this paper, we base on the three theorems of the electric field, continuous ultra-relaxation iterative algorithm, and Lagrange interpolation algorithm. We use the C language as a programming tools, and transform the model derived above into a CAD software to calculate the electric potential in the image tube. In case the image tube parameters and electrode potential are known, the program written can get the potential of every point in the image tube, and plot equipotential lines inside the image tube. It can also get the potential of every point on the axis of symmetry by Lagrange interpolation. )
