摘要: 通过大量实例讨论了气体在地震地下流体宏观异常中的作用。地下水中气体成分及含量的变化, 可以引起一系列的物理、化学反应, 是产生流体宏观异常的一个重要原因。因气体参与的化学反应, 引起一部分元素的迁移或析出, 可导致地下水发浑变色。气体逸出可引起地下水流量、水位和温度的显著变化。震前地下水中气体的释放可以达到较大的数量与规模。

Abstract: In this paper, through large quantity of exam ples, the gas function in the underground fluid of the earthquake m acroscopicanomalies is discussed. The variation of gas com position and content in groundwater can cause a series of physical and chemical reaction, as an importantreason, it produces the anomalies of underground fluid. With the gas chemical reactions, some chemical elements movedordeposited, and then cause the groundwater to become muddyor change colors. The gas spilling can make notable variation of the groundwater flow, water level and temperature. Gas relea sing from groundwater before an earthquake can reach large quantity and scale.

Key words: Underground fluid, Macroscopicanomaly, Gas
