| 摘 要： | 对云龙台的水管倾斜仪观测数据进行了倾斜固体潮的潮汐分析，发现ＥＷ和ＮＳ两个分量的振幅因子异常变化与地震有较好的对应关系。由于潮汐分析方法本身的科学性和严密性，故振幅因子误差小、精度高；又因为对潮汐谐波波群的选择，避免了以太阳日为基础的周期性干扰，Ｍ２、Ｏ１波振幅因子的地震异常识别则简易可行，并且可信度高。云龙台的固体潮观测具有较强的地震监测能力。

| Abstract: | Based on the water tube tiltmeter observatory data, the author analyses the ground tilt tide, finds that the abnormal change of amplitude factors of EW and NS componts is corresponding to earthquakes. Because the tidal analysis method has its own science and close, the error of amplitude factors is small, its accuracy is high. The choice of the tide harmonic waves group avoids the periodicity interference of the solar day, the seismic anomaly discriminance of M2 and O1 waves amplitide factors is simple and easy to operate. and the credibility is high.The solid tide observation has higher seismologic surveilance ability in Yunlong station. |
