中国大陆及附近地区大地震重现的周期和量级的分布律
DISTRIBUTION LAWS OF RECURRENCE PERIODS AND MAGNITUDE SEQUENCE OF GREAT EARTHQUAKES IN MAINLAND CHINA AND ITS SURROUNDING REGIONS

摘要: 本文给出了中国大陆及附近地区大地震重现于活跃期的周期是近似地服从数学期望,m=39.5月,=3.3月（2--方差）的正态分布律,而重现的量级序列可近似地被一个非齐次（或非均匀）的马尔科夫链所描述.Abstract: In Mainland China and surrounding regions, the recurrence periods of great earthquakes obey nearly the normal distribution law with mathematical expectation m= 39.5 months and = 3.3 months (variance 2) within a seismic active time interval while the recurrence magnitude sequence may be described by a nonhomogeneous Markov chain.
