《地震战线》1980年第4期刊登了“对二倍法的疑问”一文,文中利用C_n~2的任意组合,再乘三倍,在假定每年出现20天异常的情况下,推出每年为570天的预报天数。 我认为,陈竹年同志的假设和计算方法在实际上是不能成立的。因为使用者都是在震例总结和大量统计结果的基础上,为探索发震时间而归纳出“二倍法”、“倍九律”的,这些方法已被实践证明在预报大震危险点方面具有一定参 Earthquake Front, Issue 4, 1980, Issue 4, “Doubt on Double Laws,” uses an arbitrary combination of C_n ~ 2 to multiply by three times. In an assumed 20-day anomaly each year, an annual 570 The forecast days of the day. In my opinion, Comrade Chen Bamboo Years’s assumption and calculation method can not actually be established. Because users are based on sum of earthquake cases and a large number of statistical results on the basis of the time to explore the discovery of the “double law”, “times nine law”, these methods have been proven in the prediction of danger points Have a certain reference
