【摘要】 根据G-R公式和非线性动力学观点,在分析不同类型地震序列震级分布细结构基础上,提出用震级变异系数δm、b值和震级熵H(m)、马尔柯夫链理论值h和信息量维数D1等统计量,来综合描述和界定不同类型、性质的地震序列;同时对截止震级问题、b值、平均震级m、h和D1等统计物理含义进行了探讨。认为δm、b值和H(m)及其与理论指数分布的震级熵H(∞)的差值ΔH(m)相结合将有助于区分前震序列、前兆性震群和各种不同类型(主-余震型、震群型、孤立型)地震序列,并且可以对这些类型进行早期判断。更多还原

【Abstract】 Based on the G-R relationship and nonlinear dynamics,we have proposed some statistical variances,i.e.,magnitude variation coefficients δ_m,b value,magnitude entropy H（m）,Markov chain theoretical value h and information fractal dimension D₁ etc.,to describe the different kinds and properties of earthquake sequences.We have also discussed the physical meaning for cutoff magnitude,b value,average magnitude,h and D₁.It is helpful to distinguish and early judge the type of earthquake sequences（foreshock,precursory swarm and mainshock-aftershock type,strong shock swarm type,isolated strong shock type） by δ_m,b value,H（m）,different ΔH（m） between H（m）,and theoretical exponential magnitude entropy H（∞）.更多还原
