Finally, the influence of permanent tide is recalculated using the same precise development of TGP. This work can be taken as a theoretical reference for the research of highprecision space geodesy and astrogeodynamics. tide-generating potential ; station displacements ; spectrum method ; Love/Shida number

最初的Love数和Shida数是由静态球形地球的潮汐模拟理论推求的，由于地球是旋转椭球形的天体，地球形变对引潮力位的响应存在着不同调和函数的微小混合，这样Love数和Shida数就与测站纬度和TGP的调和级次有关，纬度特性可通过引入一组常数来表示，最初的结果由Wahr
