Association rules mining is a very active field in data mining and there are many algorithms today. In this field, the most classical algorithm is Apriori put forward by Agrawal et. al and it is used widely. The paper analyzes the advantages an disadvantages of Apriori, AprioriTid and AprioriHybrid algorithm in mining association rules. To solve the bottle of AprioriHybrid algorithm, a Support-Matrix method to rapidly verify the 2-frequent itemsets is put forward. To accelerate the speed of verify the k-frequent itemsets, a simple and highly efficient method of minimizing the trade database is given. All these two methods improve the efficiency of AprioriHybrid method.

关联规则挖掘是数据挖掘中一个非常活跃的领域，当前有许多种算法，最经典并被广泛使用的是Agrawal等人提出的Apriori算法及其衍生算法，本文分析了Apriori，AprioriTid和AprioriHybrid算法的优缺点，针对AprioriHybrid算法的瓶颈提出一种使用支持度矩阵对频繁2项集快速验证的方法，并给出一种简单易行，而又高效的逐步缩减交易数据库的方法，加快对候选频繁k项集的验证速度，从而提高了AprioriHybrid算法的效率。

Dichlorvos was once a good product and widely used for its outstanding effect on knocking down insects and easy volatilizing. But DDVP and chlorpyrifos are limited to use for the reason of safety. According to the recommendation of WHO, a new miticide,pirimiphos-methyl, was developed by Hunan chemical academy in 1999. It can be used for controlling mosquitoes, flies, cockroaches and mites et al.

有机磷杀虫剂中的敌敌畏由于具有击倒作用与杀灭能力较强，又有自然挥发功能，所以，是应用最广的品种，但DDVP在卫生杀虫剂中已处于限制使用状态。1999年，湖南化工研究院，根据WHO的推荐，研制开发了广谱，速效杀虫，杀螨剂—甲基嘧啶磷，可用于防制蚊，蝇，蟑螂和螨等。
