在探讨地震预报时,作为一个预报因子,国内外不少人都注意到太阳活动与某些大震有一定的关系。 本文应用1877—1976年一百年来我国大陆(包括渤海,下同)7≥级大震及太阳黑子资料作了初步分析并进行统计假设检验(x~2检验),得出了一些有意义的结 When discussing earthquake prediction, as a predictor, many people both at home and abroad have noticed that the solar activity has certain relationship with some major earthquakes. This paper makes a preliminary analysis of the 7 级 class large earthquakes and sunspots in mainland China (including the Bohai Sea, the same below) from 1877 to 1976 and conducts statistical hypothesis testing (x ~ 2 test) to get some meaningful results The knot
