通过气压变化对重力观测的影响和大气潮对重力固体潮的负荷效应二方面的研究 ,得出将 GS型重力仪置于密封装置 ,能使气压的影响量降低 1个数量级。谱分析结果表明 ,大气潮使S1波的振幅增大 1 0 % ,引起相位偏差约 1 0°,使 K1波和 S2 波的振幅分别增大 0 .2 %和 0 .37% ,而对其他主波的影响不大 ,使用中可忽略 Through the study of the effect of barometric pressure on gravity observation and the effect of atmospheric tide on the load of gravity solid tide, it is concluded that the GS gravity meter can be placed in a sealing device to reduce the influence of barometric pressure by one order of magnitude. The results of spectral analysis show that the amplitude of S1 wave increases by 10% due to the atmospheric tide, causing a phase deviation of about 10 °, increasing the amplitudes of K1 and S2 waves by 0.2% and 0.37% respectively, while for other The impact of the main wave is small, can be ignored in use
