| 摘 要： | 本文讨论海水质量守恒改正和等潮图的差异对计算负荷效应的影响,并研制海潮主要分波的球谐模型。数值计算结果表明:在按Schwiderski全球1°×1°等潮数据计算中国大陆的海潮负荷效应时,须用我国更精细的近海潮汐资料对其进行修正,同时还应该进行海水质量守恒改正。用褶积和级数相结合的方法计算倾斜海潮负荷潮的精度为0.04ms。

| Abstract: | This paper deals with the effects of conservation of mass and discrepancy of cotidal charts on Loading tidal computations, and handles the spherical harmonic model of the main constituents of ocean tide.The numerical results show that it is necessary to modify schwiderski's glodal 1°×°1 cotidal data using much detailed costal cotidal data while computing ocean loading tidal effects in the mainland of China. Meanwhile, correction of mass conservation should be applied to the cotidal data The accuracy of tilt loading tide computed by means of integral technique in the inner zone and spherical harmonic expansion in the outer area is about 0.04ms. |

| Keywords: | loading response of ocean tide cotidal chars conservation of mass sea tidal spherical harmonic model. |
