Role of active oxygen species in diethyldithiocarbamate-induced gastric ulcer in the rat

Diethyldithiocarbamate, an inhibitor of Cu,Zn-superoxide dismutase, was recently found to be ulcerogenic in the rat stomach, and active oxygen species were found to be responsible for its ulcerogenicity. To clarify which active oxygen species play a role in ulcerogenesis, the effects of various scavengers and iron-chelators were studied. As superoxide dismutase and catalase reduced the ulcerogenesis induced by diethyldithiocarbamate, the superoxide radical and hydrogen peroxide were considered to play a pathogenic role in this ulcer model.

黑河分层型水库水量水质综合优化调度的研究

本文分析了黑河水库水温、水质与黑河水库取水建筑物的关系。建立了黑河水库水库水量水质综合优化调度的动态确定性多目标非线性数学模型。并按逐次逼近的逐步优化法（ＰＡＰＯＡ法）对数学模型进行求解计算。经分析计算证明，该数学模型概念清晰，结构合理，计算精度较高，且优化迭代计算速度快，占计算机内存量小，避免了动态多目标优化中的“维数灾”。可供规划、设计及管理等阶段在分层型综合利用的水库水量水质综合优化调度中使用。

Retrospect and Prospect of the Influence Diagram

The evaluation algorithm and the application of the influence diagram were surveyed, which argues that to construct an explicit,compact and objective influence diagram is of the most importance. There are two suggested ways for realization of the influence diagram: introducing the achievements of the modern psychology, cognitive science, behavior science, and so on to represent and solve uncertainty to build a well-constructed influence diagram; based on the observed data to build an influence diagram. Also, the limitations of the influence diagram were analyzed, such as that it cannot deal with asynunetric problems efficiently, cannot picture dynamic problems,cannot model the problems with a limitless horizon, and ther is no highly efficient algorithm. And some potential methods to overcome these limitations were pointed out.     

运用系统思想探讨再造工程的有效实施

激烈的竞争环境给企业提出了改革的要求，而单个过程或局部功能的改造只能带来有限的收益，于是一种以先进信息技术为支持、以优化企业策略为主要措施的再造工程技术应运而生。对于实施再造工程的每一分阶段——目标设定、设想创建、措施设计及付诸实施——都必须从系统观点出发加以深刻理解，并运用系统方法进行组织管理方可达到实施的有效性。     

机械合金化与等离子体烧结法制备CoSb3热电材料
