【摘要】 本文分析了孟连地震至包头地震期间中国发生的五次地震的天体位置.该五次震例都处于朔望日发震,且交替呈现,为中国地震史上最集中出现的群发朔望震.对此本文作了一些朔望对地震发机制的初步探讨,此外,也对引潮加速度对地震触发作用进行了计算和分析更多还原

【Abstract】 s The analyses of the positions of celestial objects during five earthquakes Which occurred from Menglian to Baotou in China are given in this present article. The five earthquakes appeared on the first or fiftwwnth day of the lunnar month alternatrly and were the syzygial earthquakes in group which showed up most concnentrativrly in the Chinese seismological history. Some preliminary approaches to the trigger mechanism of erthquakes by syzygy are proposed and the trigger effects of the tidal acceleration on earthquakes are also calculated and analysed.更多还原
