| 摘 要： | 弥渡地器台经过多次试验，在2011年11月改进了弥渡自流井脱气集气装置。该装置在弥渡地下流体观测井使用后，脱气效果明显，弥渡地下流体前兆信息获取能力得到较大提高。本文选取改进脱气集气装置后的弥渡数字化气汞资料，对2012年以来云南省内发生的几次中强地震进行了分析、研究。

| Abstract: | Based on many results of experiments, Midu Seismic Station improved the observation methods of degas- sing and collecting gas device in November 2011. We use this method to Midu underground fluid observation and we found that the degassing effect and the ability to obtain the underground fluid＇s precursory information of the de- vice have been greatly improved. The observation data of improved method responded some moderately strong earth- quakes in Yunnan Province since 2012. It is useful to both the recognition of abnormal morphology and summarizing the characteristics of seismic precursor anomaly of Midu digital gas mercury observation. |
