A DIFFERENTIAL ANALYTICAL-REPRESENTATION OF THE THEORETICAL VALUE OF EARTH TIDE AND THE FIT-TESTING OF EARTH TIDE DATA
Jie Sheng Jiang · Chinese Journal of Geophysics · 1994
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.
