【摘要】 该文用O—1序列统计分析及自相关分析方法讨论了我国及分区地震活动性。确定判决水平MD后可将地震序列转化为0—1序列。子序列Lk变化情况反映了大于某一级地震的重复特征。1897年—1983年我国地震序列在K=4、8、10时Lk为高值,序列的自相关函数ρ在τ=4时为0.38,置信水平α=0.01。对我国分区的地震序列进行了类似的分析。更多还原

【Abstract】 Seismic activities in China and subrcgions are discussed by binary statistic analysis and autocorrelation analysis. Seismic series may be transferred to binary series after fixing determinative level. The changes of subseries Lk indicate repeated character of earthquakes greater than some magnitude M. The values of Lk arc high as K=4, 8, 10 in analysing the seismic series in China during the period 1867-1983 and the autocorrelation function pr equal to 0.38 as τ= 4 at 1％ significance level. The seismic series in the subregions are similarly analysed.更多还原
