| 摘 要： | 用卡方检验的数理统计方法,结合华北地区活断层、震源机制解等地震地质构造,对华北地区3次强震前的地震活动进行了时间及空间上的检验.认为,卡方检验不仅揭示了中强震前地震的丛集特性,而且体现了强震与地震地质背景之间的密切关系,揭示了构造体系与地震的某些联系.

| Abstract: | Time and space tests for seismicities before 3 strong earthquakes in North China,by using the mathematical statistics of Chi-square test,combining seismotectonics such as active faults and focal mechanism solutions of North China.The results show that Chi-square test can reveal not only the swarming feature of earthquakes before medium and strong earthquakes,but also close relation between strong earthquakes and seismotectonic background. |
