摘要
根据直角坐标x、y、z与球坐标r、θ、φ之间的关系,由直角坐标系中拉普拉斯算符的表达式推出球坐标系中拉普拉斯算符的表达式。
In This paper, The representative of Laplace＇s Operator of Spherical Coordinate System was obtained from the representative of Laplace＇s Operator of rectangular Coordinate System by the relationship of x, y, z of rectangular Coordinates and r、θ、Ф of Spherical Coordinate.
