| 摘 要： | 剔除库尔勒体应变观测资料中地震波、仪器标定及明确原因的干扰数据,计算应变潮汐因子、高频信息和非潮汐速率,结果显示：O1波、半日波潮汐因子在轮台5.4级、新源-和静交界6.6级地震前存在明显的异常反应,潮汐因子曲线形态、周期均发生明显的异常变化,异常结束后2-3个月内发震.总结体应变观测资料的异常特征,可有效捕捉前兆异常变化信息,有助于提高台站的地震短临预报水平.

| Abstract: | After eliminated the earthquake singles,calibration singles and known intereferenc singles.The body strain observation data are used to calculate the strain tide factor,high frequency information and non-tidal velocity.The result shows that there are clearly anomalous response in O1 wave and half-day wave tide factor before two earthquakes,one 5.4magnitude in Luntai and another 6.6 magnitude in the border of Xinyuan and Hejing,anomalous variation occured in the curve shape and period of tide factors.The earquakes occurred 2-3 months later after the anomalies disappeared.Summarizing the anomaly features of body strain observation data,the procursory information can be obtained effectively and the capabiliy of short-term and immediate prediction in stations can be improved. |
