应变固体潮理论值计算及其调和分析

本文给出了计算应变固体潮理论值的“封闭公式”和调和分析公式。采用了A.T.Doodson引潮位展开,推导了应变固体潮的大地系数和相位改正（长周期波、全日波、半日波和1/3日波）,可供调和分析之用。并通过Venedikov调和分析计算,对理论值公式进行了验证。文中还列出了三个台站的首批应变固体潮观测资料的维氏调和分析结果。

CALCULATION OF THEORETICAL VALUE OF STRAIN TIDES AND ITS HARMONIC ANALYSIS

In this paper, the formulae of theoretical value of strain earth tide and the harmonic analysis formulae are derived. The authors have developed the geodetic coefficients and the phase correction of strain earth tides （long periodic waves, diurnal waves, semidiurnal waves, terdiurnal waves） by means of Doodson's harmonic development of the generating tide potential. The formulae of theoretical values have been checked by using Venedikov's harmonic analysis. In order to indicate the development and the level of the observation of strain earth tide in China today, the first results of harmonic analysis of the observation data from three stations have been shown.
