Don't get things mixed up, just the z component of the force becomes Gm triple integral of delta cos phi sine phi d rho d phi d theta.
不要搞混，只是力的z分量罢了,它是Gm∫∫∫δcosφsinφdρdφdθ
Tt is suggested in this paper that the calculation of the gravitational anomaly is performed by boundary elements method, curvilinear integral is for 2-D object and surface integral for 3-D object.
本文提出用边界单元法计算重力异常，二维形体用线积分，三维形体用表面积分。
