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。
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.
