The association rules of the traditional data mining technique are used to mining higher appearance frequency and support for itemsets. If the association rules are applied to mining the outbreak symptom of excrescent disease, the support of partly outbreak symptom not high will be ridded during the mining process. The reason is that the number of excrescent disease patients is less than the number of ordinary patients. In addition, the outbreak symptom of excrescent disease may have the successively order of time happened, for example, symptom B will just take place sometime of interval later after symptom A. The data mining techniques that generally direct against the higher appearance frequency itemsets and only consider the single dimensional sequential pattern cannot totally search the pattern of outbreak symptom of excrescent disease, and cannot also provide related reference information to prescribe medicine for nursing staff at that time.

由於传统资料探勘技术中之关联规则是用来针对资料集合中出现频率较高亦是支持度高之项目集合进行探勘，若是应用於异常疾病发病徵状样式之探勘，由於异常疾病病患人数不及於普通疾病病患人数之缘故，因而造成部份发病徵状之支持度不高，将会在探勘过程中被去除，另外这类异常疾病之发病徵状可能会有先后发生时间之顺序，例如症状A发生后间隔一段时间后才会发生症状B，所以一般针对高频项目集合且只考虑到单一顺序维度之资料探勘技术，并无法完全找寻出这类异常疾病发病徵状之样式，也就无法在第一时间内提供医护人员对症下药之相关参考资讯。

During the preparatory periods of the Haicheng earthquake and Tangshah earthquake, the occurrences of the stronger earthquakes in the precursory field were related to the moon's phase, the M_L≥4.5 earthquakes of the near-focus field in the trend precursory periods and the M_L≥4.0 earthquakes of the whole precursory field in the periods of the fast-changing precursors tended to occur around syzygy or quarter.

海城和唐山地震的孕震期间，前兆异常区域内的较强地震趋于发生在朔望和上下弦，海城和唐山地震的主序列以及前兆异常区域内1900年以来发生的六级以上强震与月相也存在类似的相关。这些关系可以在地震预报中作参考。

There were 10 seismometric stations （ including telemetric stations ） and 13 precursor monitoring stations with 17 observation items within the distance of 300 km from the epicenters. There were 18 medium term, short term and imminent anomalies. 7 of them were anomalies in seismic activity and 11 items were precursory anomalies. The proportion of precursory anomalies within the distance of 200 km from the epicenters was 73%.

在1994年度青海省震情研究报告中，根据青海东部存在的地震活动性异常和部分前兆观测异常，将共和地区列为应注意地区2）。2月16日5.8级地震前，根据地震前兆的短临异常，青海省地震局于2月12日填报了短临预报卡片（除共和地区外，同时还圈定了两个地区），并电话通知了共和县塘格木农场，14日向省政府做了汇报，省政府根据震情的发展用电报通知了海南州政府3）。
