水文地球化学映震机理的组分谱系分析

<正> 以前人们讨论的重点是水氡的前兆机理问题。氡与其他化学组分比较有两个显著特点:其一在于它是半衰期比较短的放射性气体,这一特点基本排除了它远离母体进行迁移的可能性;其二在于它是一种惰性气体,和其他惰性气体一样,不可能由于某种化学反

ANALYSIS OF SPECTRUM-SYSYTEM OF HYDROGEOCHEMICAL COMPOSITIONS RELATED TO EARTHQUAKE MECHANISM

This paper mainly discusses the responses of various hydrogeochemical compositions with diffrent physical-chemical properties to stress-strain and the associated effects. It points out that the changes of hydrogeochemical compositions are probably caused by spreading of crack, mixing of groundwater changing of pressure, thermal effect, vibration and so on.The mechanism is analysed. Before earthquakes, anomalous changes of mang kinds of compositions often occur due to the complexity of stress-strain and the associated effects as well as the difference of properties of various compasitions. There is probably a complicated relation among various compositions in synchronism, grouth and decline and etc. Thus, choosing better sites for comprehensive observation of hydrogeochemical parameters is useful to us in distinguishing anomalies, removing disturbance and analysing mechanism of anomalies.
