大地测量中的永久潮汐问题

摘要

This paper is devoted to treating the permanent tide in geodesy. First the numerical expression of the permanent tide potential is derived, then formal expressions of three kinds of tidal values and transformations among them for six types of geodetic observables frequently encountered are given, and finally the characteristic and usage of the three tidal systems in geodesy are discussed.%研究大地测量中永久潮汐的处理问题。首先推导永久潮汐位的数值表示式，接着给出6类常遇到的大地观测量的3种潮汐值形式及其转换关系，最后讨论3种潮汐系统的性质及其在大地测量中的使用问题。
