We are finding a parametric equation for the sphere using two variables phi and theta which happen to be part of the spherical coordinate system.
我们建立有两个变量φ和θ的球面的参数方程,它们恰好是,球坐标系统的一部分。
According to the definitions of grads, divergence and rotation, the expression in spherical coordinate system is given from the point of physics.
据梯度、散度、旋度的定义，用物理的方法给出了在球坐标系中的表达式；此方法也可以推广到其它的正交曲面坐标系中。
