| 摘 要： | 通过对库尔勒铁门关体应变3年的观测资料进行可靠性分析认为本台站资料达到了Ⅰ类台精度,干扰主要为气压效应和水位干扰,观测资料记录到的固体潮清晰.利用低通滤波和一阶差分的方法,可以识别出固体潮畸变.对识别出的48次固体潮畸变现象进行了统计,统计结果表明,6次畸变为干扰,13次近震前存在固体潮畸变现象,其余畸变发生在强远震前... |

| Abstract: | In this paper,the reliability analysis of volume strain observational data for three years in korla station show the observation accuracy achieve I station's accuracy.The main disturbance is air pressure effect and water level interference.The observational data can record the clear solid tide.We distinguished 48 distortion of solid tide by low pass filtering and first difference.The statistical result shows 6 distortion was interference,13 distortion appeared before near earthquakes,and the others appeared... |
