立体的等势面,用matlab软件可以精确计算并作3D图,易学华等提到,用常微分方程计算出平面等势线的坐标xx,yy,通过坐标旋转,就可以作出等量同种点电荷、等量异种点电荷的立体等势面.我们这里提出一种新的作法,程序设计的原理是,只要给出电荷分布,计算出空间各点电势,连接等电势的点形成立体等势面,这种方法具有普遍性,因此可以用在任意电荷分布的情形.
Three-dimensional equipoise surface, with matlab software can accurately calculate and make 3D map, Yi Xuehua, etc. mentioned, using ordinary differential equations to calculate the coordinates of the equipotential line plane xx, yy, through coordinate rotation, you can make the same amount of the same species Point charge, the same amount of heterogeneous point charge three-dimensional potential surface.We propose a new approach here, the program design principle is that as long as the charge distribution is given, calculate the potential of each point in the space, connect the potential and other points to form three-dimensional Potential surface, this method is universal, it can be used in the case of any charge distribution.
