The possibility of temporal variations in the earth tidal amplitudes associated with earthquakes has first been suggested by Nishimura. 西村首先提出与地震有关的固体潮振幅随时间变化的可能性。
That concludes these instruments with different baseline and different working principle, can observe comparable earth strain in the solid tidal band. 证明这两种基线长度和安装方式不同的仪器，观测到的地层应变在固体潮频段具有可比性。
