中国大陆M2波理论应变潮汐模型

本文主要研究和讨论了我国大陆固体潮和海潮负荷效应的M₂波理论应变潮汐模型。推导了球扇波应变张量大地系数和计算公式,着重研究和计算了M₂波海潮应变负荷效应,讨论了计算方法,计算中采用了到目前为止最新的Schwiderski（M₂）全球海潮图和沈育疆近中国海潮汐图;给出了40个点的负荷效应结果,并绘制了中国大陆固体应变潮、海潮应变负荷效应同相位,相差π/2相位以及总效应的应变花。为理论研究,观测资料的分析和改正提供了理论参考模型。

THEORETICAL MODEL OF STRAIN (M_2 WAVE) TIDE IN CONTINENTAL CHINA

This paper deals with the problem of the theoretical model of strain (M2) tide formed from both solid tide and the effect of ocean tide in continental China.The geodesic parameters of strain tensor for semidiurnal tide, as well as the formulas, are developed. The effects of ocean tide on strain (M2) are mainly studied and calculated. The calculation methods are discussed and the results of 40 points are given. In calculating, the global ocean maps (Schwiderski, 1979) and those close China (Shen Yujiang, 1980, 1985) are used together. Then, "strain flowers" for some cases are ploted. Above results provide the theoretical reference for both theoretical investigation and observational analysis.
