本文根据历史地震资料按最大熵谱方法对全球及全球各地震区强震活动的时间序列进行了分析。
Based on the historical seismic data, we have analysed the time sequence of the global and regional strong earthquake activities by using the maximum entropy spectrum method.
研究结果表明：地震分布的多重分形维数谱和奇异性谱对于一些典型震区的强震发生具有中期预报价值。
The results show that the medium term symptoms of strong earthquakes in some regions can be proposed from the multi fractal dimension spectrum and singularity spectrum of earthquake distribution.
强震的孕育和发生不仅与震中周围构造有关，而且与孕震区所在的整个构造带有关。
Conceiving and occurring of strong earthquake are closely related not only with tectonic area of epicenter but also with whole tectonic zone.
本文对思茅、普洱地震区1972年——1981年期间，强震前的小震活动图象进行了分析讨论。发现，中强震前有震面积百分比逐渐增高，在达到峰值时往往有强震发生。
In this paper, activity patterns of small earthquakes before strong ones in the Simao-Puer seismic area during 1972-1981 have been analysed and discussed.
