In this paper, correlation decree of the nine strong events versus the precursory data of Haicheng earthquake has been calculated by using correlated space theory of grey system, while fuzzy cluster analysis is clone on the 7 event data, obtaining much more consistent results. At the same time, the data requirements by the two methods are compred. In order to study effects by different factors, calculation of correlation degree between source parameters of the nine strong events and their aftershock sequence data is also made. The results indicate that correlation degree and correlation sequence of the precursory data, source parameters and aftershock sequence of the same event might be some different. Possible reasons that cause such differences are discusst.d in the paper,suggesting that as for the better predicted Haicheng and Songpan earthquakes, both are characterizing as small correlation degree on the precursory data, being the most late correlation sequence of each event. There are also two types of varied results from fuzzy cluster analysis, indicating that they are two different types of precursory data in earthquake prediction,

本文用灰色系统的关联空间理论计算了九次强震对海城地震的前兆数据的关联度值,并对七次强震的前兆数据进行了模糊聚类分析,得到了较为一致的结果。并用两种方法对数据的要求进行了比较。为了研究各因素的效应,对九次强震的震源参数和余震序列数值的关联度以一并计算出来,结果显示出同一地震的前兆数据、震源参数和余震序列的关联度和关联序都可有一定差异。文中讨论了形成这种差异的可能原因,并得出进行过较好预报的海城地震和松潘地震二者在前兆数据上关联度小,为各次地震中关联序最后者,模糊聚类的结果也是不同的两类,从而说明了这是两次不同类型的前兆数列的地震预报。

On the basis of the principle of statistical pattern recognition and bymeans of the time series of the sound signals of the internal combustion eng-ine, a new method for failure diagnosis of the internal combustion enginehas been developed. Autoregressive coefficients and autoregressive cepstralcoefficients are used as the feature vector of pattern. The relational measureof grey system, the measure of the Mahalanobis distance. and the measure ofdistance of the quantity of information of Kullback-Leiber are employed fordiscriminating the testing pattern to see to which reference pattern it belongs.The results of every discrimination are synthesized by AHP (analytic hierachyprocess). Then the goal of diagnosis is achieved. The method has been verif-ied in a process for diagnosing Diesel Engine-19% in laboratory. The theore-tical and experimental results have shown that the method is practical andeffective.
