| 摘 要： | 本文采用全微分法，导出了直接而严密的固体潮理论值对时间一阶微商的解析表达式．将其应用于固体潮资料的拟合检验，确保了理论上的严谨性和计算精度．文中还介绍了部分拟合检验的应用实例，并与不同拟合方法进行了对比分析，表明全微分法在运算处理速度上与谐波展开法和数值微分法相比得到了成倍的提高，而与天顶距微分法的运算速度相同．

| Abstract: | In this paper,a direct and accurate analytical-representation differentiating the theoretical value of earth tide with respect to time Is driven by the total differential method.It is applied to fit-test the data of earth tide. Both the strictness on theory and the precision of calculation are ensured, and also high efficiency on operating speed is obtained.Finally,some practical fit-testing examples are given,and the different fit-testing methods,such as the harmonic development waves me thod,the differential method,the method of zenith distance differentiation,are compared. |
