摘要
从氡的地球物理特性、氡气测量方法的原理,阐述氡气测量技术在地震前兆观测的应用研究现状。通过对下关温泉水样和氡气固体源在不同静置时间下的测值试验,认为水氡观测中静置时间在80—100 min的测值,观测结果要比静置时间1 h合理,而且测值明显增大。
The authors give an overview on geochemical and geophysical teatures oi water ~auu~ ~,u ~ vant monitoring technique and principle as well as the significance of water radon monitoring in earthquake precursor observation and research. According to the comparison tests for time of storage of standard source of radon and water samples from Xiaguan hot spring, we found that the 80-100 minutes time of storage for radon monitoring is better than the 1 hour, which is the conventional storage time, because the obviously bigger value can be derived.
