Research on geo-electrical resistivity observation system specially used for earthquake monitoring in China

This paper deals with the design and development of the observational system of geo-electrical resistivity on the basis of the demands for exploring the temporal variations of electrical properties of Earth media in the fixed points of the networks, which would be associated with the earthquake preparation. The observation system is characterized by the high accuracy in measurement, long term stability in operation and high level of rejection to the environmental interference. It consists of three main parts, configuration system measurement system, the calibration and inspection system.     

过渡带拼接地震资料处理方法研究

本文针对滩海过渡带及多个相邻区块资料拼接的工区情况,提出了一系列的解决方案:包括匹配滤波因子的计算、时差的判别、相位差判别,频率匹配,异常能量压制,振幅补偿等联合处理方法,最终很大程度上实现了包括能量差、频率差、时差以及相位差的消除,有效解决了由于滩海过渡带地表条件极其复杂,地震激发、接收环境差、差异大而引起的地震资料分辨率与信噪比低、成像和一致性差的问题.
