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.)

Design DC supply with filter circuit in PSCAD

二维均匀各向同性介质弹性波动方程有限差分波场模拟(Two dimensional homogeneous isotropic medium elastic wave equation finite difference wave field simulation )

PSCAD下调用matlab进行傅里叶分析的实例。因节点数超过15个，需要高于在学生版PSCAD中运行。(Example case for fourier analysis calulation using MATLAB.This case will not run on the Student Edition of PSCAD because it has more than 15 nodes! )

这是我做的10KV变电站标准设计图纸，包括电气主接线等，用的AutoCAD画的，朋友们可以放心下载，已经通过了毕业答辩。(This is what I do 10KV substation standard design drawings, including the main electrical wiring, etc., with the AutoCAD drawing, and friends can rest assured download, has passed the graduation reply.)

说明：  这个软件是用在CAD里的，给尺寸加公差上去很方便。(This software is used in the CAD in the, tolerances up to plus size is very convenient.)

用5阶weno格式求解sod激波管问题，画出了t=0.14时刻的密度，速度和压力的分布曲线(solve the problem of shock wave in tube by using the 5 order WENO format)

说明：  上大学时候的一个习作，是模仿国外一个截图软件做的。它不但可以抓图，而且还可以选择抓图的形状，比如圆形、方形、三角形等。还有其它的一些辅助功能有很多(When one exercises in college, is an imitation of a screenshot of foreign software to do. It can not only drawings, but can also choose the shape of drawings, such as round, square, triangle and so on. There are some other auxiliary functions, many)

用四阶龙格-库塔法求系统在U单位阶跃输入下该系统的响应曲线(Using the four order Runge Kutta method to find the response curve )

本程序是计算机图形学课程设计的程序，包含用各种算法绘制直线、圆、曲线，填充，剪裁等，有助于计算机图形学的学习与实践。(This procedure is a computer graphics curriculum design process, including the use of various algorithms to draw lines, circles, curves, filling, cutting, etc., help to learn and practice of computer graphics.)
