Puts forward a simple method using the transitional matrix. Firstly transforms Cartesian coordinates of stress tensor,which in Navier-Stokes equation,to spherical coordinate,then does vector transform of spherical coordinate to Navier-Stokes equation.

• 本文利用过渡矩阵；先把Navier-Stokes方程中的粘滞应力张量由笛卡儿坐标系变换到球坐标系；然后对Navier-Stokes方程进行球坐标列矢量变换.
