解析法面积计算,读数据文件,计算后生成结果文件,任意多边形的顶点坐标,然后 计算出面积是平方米和公顷(analytical calculation, reading data files, calculation results generated documents, arbitrary polygon vertices, then compute the area of square meters and ha)

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 )

简单计算机图形学算法，通过直线中点Bresenham算法,绘制直线。( Simple computer graphics algorithms, Bresenham line passing through the midpoint algorithm, draw a straight line.)

简单画图板，初学者实用，比较简单，如果喜欢可以下载来看看(Simple drawing board, beginners practical, relatively simple)

创建文件，不且把文件传递给CAD模板。很专业##############(Create the file and the file passed to the CAD template. Very professional##############)

可以动态移动的尺度的设计，适合图形显示和控制(The scale can be designed to dynamically move, for graphics display and control)

80 纤维取向为设置的方向，20 为随机。利用Koch曲线模拟非织造纤维网。(we simulated various kinds of nonwovens through programming with Visual basic,in which 80 fibers are oreintation,20 are random. )

实现本机流量监控绘图，测试可用，方便安全(Netflow monitoring)

off 转stl ，很好的转换软件源码。实现了off三维格式向stl三维格式转换，可用于CAD、ProE等软件对接。( Turn off to stl, good conversion software source code. Off to achieve a three-dimensional format stl three-dimensional format conversion, it can be used in CAD, ProE and other software docking.)
