摘　　要：在月球和太阳的引力作用下,地球的固体表面也发生与海水表面类似的周期性涨落,这种现象称为固体潮.固体潮的形成原因与海潮相同,但其计算问题远比后者复杂.本文用开尔文地球模型和比较简单的方法计算固体潮相关的地球表面方程和涨落幅度,并进行相关问题的讨论.Under the gravitational action of the moon and the sun,the earth's solid surface also has periodic fluctuations similar to the sea surface,this phenomenon is called solid tide.The cause of formation of solid tide is the same as that of sea tide,but its calculation is much complicated more than that of the latter.In this paper,the Kelvin earth model and a relatively simple method are used to calculate the earth’s surface equation and fluctuation amplitude,and the related problems are discussed.
