| 摘 要： | 在假设地震断裂系统具有分形特征前提下，推导出非线性震级－频度关系公式：ＬｏｇＮ＝ａ＋ｂ△Ｍ－Ｃ／△Ｍ，作为示例，用此公式对一些实际观测资料进行了最小二乘拟合，效果明显好于线性公式。

| Abstract: | The fuzzy fractal values of seismic precursors for ground fluids before the 1983 Heze earthquake of M=5 9 and the 1995 Changshan earthquake of M=5 2 are calculated by using fuzzy fractal method combining fuzzy set theory with fractal theory.The results show that fuzzy fractal values reflect structure variation characteristics of observation data of time sequence for seismic precursors,have some physical significance and provide a new method for extracting seismic anomalous information from complex precursor data of ground fludids.However,the variation characteristics of fuzzy fractaly values and seismic precusor aomalies for some observation items and at some stations should be analysed specifically. |
