选择江苏省常熟地震台SQ -70型石英水平摆倾斜仪EW和SN方向 1 985～ 1 998年的固体潮观测资料 ,采用Venedikov调和分析方法计算 ,提取了倾斜固体潮全日波 (O1)和半日波 (M2 )的潮汐因子γ及相位滞后因子△φ值 ,分析了其在江苏中强地震前的变化特征 ,认为固体潮调和分析方法具有较好的地震预报效能
The observation data of solid tide from 1985 to 1998 in EW and SN of SQ-70 quartz horizontal pendulum inclinometer of Changshu Seismostat in Jiangsu Province were selected and calculated using Venedikov harmonic analysis method. The data of full tidal wave (O1) and half day The tidal factor γ and the phase lag factor △ φ of the wave (M2) are used to analyze the characteristics of the wave trough before the strong earthquakes in Jiangsu Province. The results show that the method of harmonic tide analysis has better seismic prediction performance
