【摘要】 2006年7月下旬—9月初,陕西华清4#泉气体总量测值出现了一次低值异常。经调查落实,此次异常不是构造活动或地震前兆异常,而是由采样扩散瓶刻度指示体积与实际体积不符引起的。9月6日的扩散瓶封存气体刻度指示体积与实际体积误差试验以及9月9日—13日的气体总量对比观测试验均证实了这一结论。更多还原

【Abstract】 Gas gross in the water dissolved gas in the No.4 spring of Huaqing appeared a low-value anomaly progress from the late July,2006 to the early September,2006.After investigation,it is found that the anomaly is duo to that the volume indicated by the scale of sampling diffusion bottle is inconsistent with the real volume,rather than tectonic activity or an earthquake precursory anomaly.Error test between the volume indicated by the scale of gas in the diffusion bottle and the real volume on Sept.6 and the comparison observation test of gas gross from Sept.9 to Sept.13 approve the conclusion.更多还原
