研究地震时,除物理方面问题外,对地震现象进行长期预报亦有重要意义。笔者对地球地震活动性与太阳活动性关系所作的研究结果证明:通过全球性特征∑E(一年内释放的地震能量总和)和 N(一年内灾难性地震的总数)所反映的地球总的地震活动性与太阳11年周期活动幕有关。同时还对1894～1976年太平洋东、西两岸海啸次数在太阳11年活动周期中的分布情况进行了研究,所得的分布与(?)和(?)的分布是同一形态,这便从另一方面证明地球 In the study of earthquakes, in addition to the physical aspects, the long-term earthquake prediction is also of great significance. The author’s research on the relationship between the Earth’s seismicity and solar activity shows that the global earthquakes, as reflected by the global features ΣE (the sum of the seismic energy released in a year) and N (the total number of catastrophic earthquakes in a year) Activity and the solar 11-year cycle activities curtain. At the same time, the distribution of the number of tsunami on the east and west coasts of the Pacific Ocean from the period of 1894 to 1976 over the 11-year solar activity cycle was also studied. The distribution obtained is the same as the distribution of (?) And (?), Aspects prove Earth
