摘　　要：对四川及邻区分别统计分析了不同地区MS≥6.0的强地震发生频率及其与太阳活动的关系。结果是,四 川MS≥7级地震多发生于太阳活动下降段及谷底段;四川各地的中强震(MS≥6.0)的发生皆与太阳活动背景 有一定的联系。The occurring number of strong earthquakes with magnitude equal to or greater than 6 in Sichuan and nearby regions and the times of the Sun' active are summed respectively. Our results show that most earthquakes with the magnitude equal to or greater than 7 in Sichuan regions occurred in the period between high and low points.
