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。

In order to investigate the relationship of solubility between vanadium and the other co-existing ion in soil. The phase equilibria of the quinary systemNaVO_3 + KVO_3 + NaH_2PO_4 + KH_2PO_4 +(NH_2)_2CO + H_2O and its five quaternary sub-systems were studied at 298K with isothermal dissoluble method. According to the reference, all these systems are not reported yet. The solubilities and the physico-chemical properties such as density, conductivity, pH value and refractive index of the equilibrium solutions were determined. Based on the determined values, the solubility stereo-diagram and projected-diagram( saturated with KVO3), projected-diagramsaturated with (NH_2_2CO, and water content diagram of the quinary system, isothermal solubility diagrams of the quaternary sub-systems, and the physico-chemical properties-composition diagrams of the equilibrium solutions were plotted.

A computer-aided local transient flow property measuring system was developed using a high speed CCD camera coupled with optical fibers in order to study the Gas-liquid-solid three-phase jet loop reactors. SnO2 crystal films were orientally deposited on the alkoxysilane molecule-coated hydroxyl glass substrates so as to prepare surface-marked particles as the tracers. An image analysis system was established to identify different phases. Stroboscopic photography was utilized to extend the measure range. The developed measuring and analysis system was capable of determining accurately the local transient flow property in a G-L-S jet loop reactor. Based on the above system, local transient flow properties of gas, liquid, and solid phase were measured and studied the influences of fluid property, operation and configuration parameters on the reactor.
