摘要/Abstract

摘要： 数字化氡在聊古一井投入观测已近4年, 与模拟水氡观测相比, 具有采样率高, 数字传输、保存和资料处理快捷方便, 人为观测误差少的优点, 从而使氡的信息量大大增加, 为捕捉地震短临异常信息提供了有利条件。对数字化氡与模拟水氡同期观测资料的对比分析结果表明, 二者的变化趋势、方差及均值变化均不一致, 数字化氡与模拟水氡观测的物理含义不同,是一种新的测项, 尚不能完全替代原有的模拟水氡观测; 数字化氡在反映地震短临异常方面优于模拟水氡; 气水分离装置(脱气装置)是实现氡数字化观测的重要基础环节, 对于获取真实可靠的观测结果具有重要作用。

Abstract: In the paper we present the comparative assessment of radon data obtained from digitized observation and waterradon data obtained from the traditional simulated observation. The digitized observation of radon has been carried out in Liaogu-1 well for nearly fouryears. As compared with the traditional simulated observation, digitized observation data have the advantages of rapid data transmission, large amount of information and lower man-madeerror. It will greatly increase the high frequency and shortperiod information of radon, and will improve significantly our ability to catch short-term and impendent precursory anomalies. The results of com parative analysis in Liaogu-1 well show that the data of radon obtained from digitized observation, including their variation tendency, Finspection and tinspection, are not identical to those obtained from traditional simulated observation in the corresponding period. It indicates that physical meaning of radon obtained from digitized observation is not as same as that of waterradon obtained from the simulated observation, and that the radon obtained from digitized observation is a new observation item. The radon obtained from digitized observation com pared with the waterradon obtained from the simulated observation has the advantages of short-term and impendent precursory anomalies. Itillustrates that gas-water separation installation is an important link torealized digital automatic observation, and is a significant function to the obtained authentic and reliable observation results.

Key words: Liaogu-a well, The radon obtained form digitized observation, The waterradon obtained from the simulated observation
