This paper believes that complex feedback systems are very common and important in the modern engineering technology. It is very difficult to resolve the optimum problem of the complex feedback system. But it has important practical value. This paper decomposed the complex feedback system into many subsystems by means of the decomposing method. First, optimize each subsystem on the optimization basis. Second optimize the whole system step by step. Finally, we provide an example of the optimal design of the heat-exchanger used in chemical processes.

作者： HU Le-wei Computer and Information Engineering Department wuhan polytechnic university wuhan China Li Yu-sheng Computer and Information Engineering Department wuhan polytechnic university wuhan China

Association rules data mining on consumers condition in commercial websites is an important aspect of research in FP-Growth *** the general application of FP-Growth algorithm,the transaction data contain only the customers’ purchase acts data,and neglect the data of acts which contain customers browsing,selecting,evaluation,this phenomenon may lead to data *** this reason,this text proposed a method which divides the customer acts data into browsing,evaluation,selection and purchasing four act data,and combines these data to the goods data,thus it can provides to commerce web site managers the results that more close to actual acts of the relevant rules.

地下室侧墙、基坑侧壁侧压力的计算通常只考虑土压力和静水压力作用,没有考虑渗流对侧墙和基坑土压力的作用,使计算值和实测值相差较大。在渗流作用下,渗流力使土的有效应力大小发生改变,从而影响土的抗剪强度。通过计算阻碍力和渗透力的相互作用,建立求解未知数方程,得到计算侧向压力的新方法,对应于不同地质状况,使侧压力的计算符合实际情况。
