【摘要】 本文应用非线性动力学中的一些观点，如对初始条件的敏感性、分形分维、分岔、混沌的预报尺度等观点对小震调制、共维时间、共维面积以及嵌套调制等现象进行了分析研究，同时对共和地震的一些现象进行了分析。本文的分析对人们认识前兆现象的复杂性有一定的参考价值。更多还原

【Abstract】 In this paper,by using some view points of non-linear dynamics,for example,sensitivityto original condition,fractal dimension,bifurcation,chaos prediction size of earthquakeprocess,and so on,we discussed the modulation triggering,common dimension time and areaand inlay modulating of small earthquakes. Author also analyzes some anomaly phenomena ofthe Gonghe earthquake in Qinghai province in 1990.The analysis has certain reference valueto understanding precursory complexity of earthquake.更多还原
