本文对中比合作和我们独立获得的共10个台站17个仪器架次2890天的固体潮观测资料采用卡特莱特(Cartwright)的完全展开和维尼迪可夫(Venedikov)方法统一地进行了调和分析,并用中井(Nakai)方法对观测资料进行了拟合预处理以提高分析结果的信噪比,同时用线性内插方法处理了仪器灵敏度以资对比.本文着重讨论了分析结果所提供的我国大陆固体潮矢量空间分布的区域性特征及其与海洋负荷的关系.结果表明:中国大陆固体潮空间分布受到海洋负荷的明显控制.O_1波尤为显著.文中讨论了仪器流变模型对观测矢量的影响.根据流变模型改正后的结果,所得到的地球对引潮力的实际响应的相位滞后,大多数发站都接近于-1°,它论证了理论原则的正确性.文中还讨论了残差矢量与海洋负荷矢量的关系,它们的一致性最概括地说明了海洋负荷对固体潮的影响.文中用误差矢量的方法研究了分析结果的精度,它说明目前海潮改正的精度仍然是不够的.在上述工作基础上,文中最后得到了经海潮改正后的 M_2波和 O_1波的观测矢量.
In this paper, the solid tide observation data of 2890 days from 17 cooperation stations of China-Belgium cooperation and our independent acquisition of 10 stations were uniformly reconciled using Cartwright’s complete expansion and the Venedikov method , And the Nakai method was used to fit the observation data to improve the signal-noise ratio (SNR) of the analysis results.At the same time, the sensitivity of the instrument was compared with that of the linear interpolation method.This article focused on the analysis of the Chinese mainland The results show that the spatial distribution of solid tide in the Chinese mainland is obviously controlled by the ocean load, and the O_1 wave is especially significant.The paper discusses the influence of the instrument rheological model on the observed vector According to the corrected results of the rheological model, the resulting phase of the actual response of the earth to the tidal force lags behind and most stations are close to -1 °, demonstrating the correctness of the theoretical principles.The residuals The relationship between vector and ocean load vector, their consistency is the most general illustration of the influence of ocean load on solid tide. Study the accuracy of the analysis results, it shows the current tide correction accuracy is still not enough. Based on the above work, the paper finally got the observation vector and O_1 M_2 wave after wave of correction by the tide.
