球体与水平圆柱体剖面磁异常Za向上延拓,关于磁法的，大家可以参考-Sphere and horizontal cylinder profile magnetic anomalies Za upward continuation magnetic method, we can refer to

本程序是基于地球物理理论中，测量得到的磁法数据需要圆滑，故而有此程序。程序使用的圆滑方式是5个点的圆滑。-This procedure is based on geophysical theory, measurement of the magnetic method of data need to be smooth, and therefore have this program. Uses smooth sleek five points.

单摆小球，下面有磁力片可以吸引改变小球的一般运动规律。是一个学习动画的不错的例子。-Pendulum ball, following a change in the magnetic film to attract the general movement of the ball. Is a good example to learn animation.

仿真模拟环形电流产生的磁场和电场，用matlab编程(The magnetic field and electric field generated by the annular current are simulated and programmed by MATLAB.)
