We led the density function into the data structure as the weight, and use dense micro-cluster to describe the arbitrary-shaped clusters in data streams. In addition, we propose candidate core-micro-cluster and isolated micro-cluster synopses to maintain and distinguish the potential micro clusters and isolation point in data streams.

我们把密度函数以权值的形式引入数据结构中，并利用核心微簇描述数据流中任意形状的簇，并提出候选核心微簇和孤立微簇结构分别用于维护并区分数据流中潜在的核心簇和孤立点。

Recently,with the higher requirement for isolation control specifications and introduction of novel actuators,researchers have already recognized the difficulty and challenge of the problems resulting from dynamic and nonlinear characteristic of actuators when design and synthetize the controller.Among nonlinearities,hysteresis is the most mathematically intractable one.

Bycomprehensive use of phytochemical isolation methods, 37 compounds were isolated 5from the methnol-chloroform extract of P. telfairia, by methods of modern spectroscopy,six compounds' structures were elucidated, including 2 kinds of fatty acids, 2 kinds ofsterols and 2 kinds of are esters of sterol and fatty acids. Five of them were reported forthe first time on the chemical constituents' research of P. telfairia. Otherwise, weperformed GC-MS analysis of the volatile fraction in this extracts, the result revealedseveral constituents such as alkyl hydrocarbons and methyl esters of fatty acids.
