摘　　要：北京西北延庆五里营井是一个对地震反映比较灵敏的井孔,其最显著的异常变化是水位的脉动和脉冲。本文用气液混合体(气、水):当流体压力沿其通道下降、溶解气体从液体中逸出的假设,解释了水位脉动(冲)的成因,结果指出了进一步研究气体的来源、变化规律及其在地震预报研究中的重要性。The Wuliying well located in Yanqing county, northwest of Beijing, is relatively sensitiveto earthquakes. The most remarkable anomalous changes of the well are the ground water levelpulses. The cause of such pulses is interpreted in this paper assuming that the dissolved gasin groundwater escapes when fluid pressure of the two-phase, (gas-water) liquid decreases alongits path to the ground surface. The significance of further research on the source of gas, itsvariation regulation and effects on earthquake prediction has been pointed out.
