Vector Transform of Spherical Coordinate Form of Navier-Stokes Equation

It is very complex to figure the spherical coordinate form of Navier-Stokes equation in fluid mechanics,so there are no solution process in many books and periodicals.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.The results are the same comparing with the classical method.
