Through study of cyclic active database rule sets and analysis of triggering graph and activation graph, we present the concept of united formula and the algorithm to determine termination of a rule set corresponding to a cyclic triggering graph. We also present the time complexity analysis of the algorithm.

我们针对有环时的规则集的终止性进行了研究，通过对触发图、活化图的分析，提出了联合公式的概念，在此基础上给出了判定有环触发图对应的主动规则集的终止性算法，并给出了时间复杂度分析。

Aiming at the multiple loop structures in quality management process network, an improved graph pattern mining approach based on Apriori algorithm is put forward, where a frequent pattern of size k, denoted as G, is joined with another frequent pattern of size k, denoted as G, to form a candidate frequent pattern of size (k+1), if there exists a source vertex s in G and a sink vertex e in G such that the graph derived from G by subtracting node s equals with the graph derived from G G by subtracting node e.

采用基于APriori方法的频繁活动序列挖掘算法，认为k-频繁图集中，当一个图减去其中的一个源顶点后，如果所得到的图与另一个图减去其中的一个沉顶点后的图相同时，可以连接生成一个(k+1)-候选频繁图，从而减少了传统Apriori算法迭代过程中生成的冗余候选频繁图的数目。

As a graphical framework for formally describing interactive system, basic graph can represent processes and the interaction between processes in two ways: one is graphical representation, where a graph corresponds to a process and reduction in a graph corresponds to interaction between processes; the other is using term algebra consisting a set of terms and an equational theory on terms.
