【摘要】 分析了2008～2009年间云南天文台光电等高仪的时纬资料的残差值的变化,讨论了残差异常变化与此期间云南天文台周围发生的2008年5月12日四川汶川8.0级地震、8月30日攀枝花6.1级地震以及12月26日昆明4.3级地震的可能的关系,并讨论了与该研究有关的问题。更多还原

【Abstract】 We analyze the variation of the residual fluctuations of the astronomical time(after correction for terrestrial coordinate change) measured by a photoelectric astrolabe in the Yunnan Observatory during 2008~2009.We probe possible relationship between anomalies of such residuals and earthquakes,particularly,the Wenchuan Earthquake(M=8.0) in May 12 of 2008,the Panzhihua Earthquake(M=6.1) in Aug.30 of 2008,and Kunming Earthquake(M=4.3) in Dec.26 of 2008,which all occurred near the Yunnan Observatory.We also discuss some problems related to the study.更多还原
