三峡工程与长江中游沿江产业带建设

讨论了长江中游沿江产业带发展条件、限制因素和未来发展，指出三峡工程的建设将对长江中游产业的布局和经济发展带来深刻的变化；防洪作用促进中游两岸大型工业项目的兴建，调整现有沿江城镇的布局，使之结构趋于合理化；电力供应经解能源的紧张状态，改善航运条件，发挥长江黄金水道的综合效益。当然，由于坝下河道冲刷，对现有的码头带来一定的影响，由于冬季水位抬升引起两岸低湖田地下水位上升，加剧两岸土壤潜育化和沼泽化。

Aerosol Scavenging: Model Application and Sensitivity Analysis in the Indian Context

Sulfate aerosols have been found to bethe major contributors to precipitation acidity. Thus,in view of the long-term ecological repercussions theyhave on aquatic ecosystems and their acidity-potential,the present analysis focuses on a case study applicationof the layer-averaged aerosol-scavenging model (Okita et al., 1996) for predicting values of the wet scavengingcoefficient and sulfate concentrations in precipitationsamples on the basis of the information available forsome selected Indian cities. Through sensitivityanalysis (Pandey et al., 1997) the scavengingcoefficient has been found to be very strongly dependenton precipitation intensity. Comparison of modelpredictions has been done with the measured values forDelhi, Mumbai, Calcutta and Chennai in India.     

C OD在线分析仪比对中应注意的问题

分析了COD在线分析仪和实验室比对结果人为差异的原因是样品不均匀,在线分析仪取样装置滤过,取样层面和采样方式以及沉淀消除的方法不同造成的.提出应在相同的地点、层面和同一容器取样,用相同沉淀消除方法去除样品中氯离子干扰,保证两方法比对中使用水样的一致均匀,使测试结果正确可信.     

中水回用工程投建与运行实践

沈阳理工大学学生城中水设施的建设，不仅提高了水资源的重复利用率，创造良好的环境效益和经济效益，同时也为中水回用工作的推广实施积累了经验。尤其是采用比较简单的污水处理工艺达到中水回用的标准，其中最主要的部分是沉淀和生物接触氧化以及最后的过滤和消毒，这样的工艺比较适合中等规模的投资，从回用水的经济效益上看这样的中水回用系统还是比较适合推广。

Using chemical process simulation to design industrial ecosystems

Chemical process simulation (CPS) software has been widely used by chemical (process) engineers to design, test, optimise, and integrate process plants. It is expected that industrial ecologists to bring these same problem-solving benefits to the design and operation of industrial ecosystems can use CPS. This paper provides industrial ecology researchers and practitioners with an introduction to CPS and an overview of chemical engineering design principles. The paper highlights recent research showing that CPS can be used to model industrial ecosystems, and discusses the benefits of using CPS to address some of the technical challenges facing companies participating in an industrial ecosystem. CPS can be used to (i) quantitatively evaluate and compare the potential environmental and financial benefits of material and energy linkages; (ii) solve general design, retrofit, or operational problems; (iii) help to identify complex and often counter-intuitive solutions; and (iv) evaluate what-if scenarios. CPS should be a useful addition to the industrial ecology toolbox.     

The Dynamic Safety Evaluation ModelOf the Safety Control Theory and Its Application

The Safety Sate Equation of theSafety System　　 Any system is moving,and the system mo-tion is the results of contradiction existing in thesystem.So is the safety system.In the safetysystem,the contradiction is the affection of thetwo concentrated variables,the hazard(H) andthe hazard control(C) .The ratio of injury anddeath of the system (Y) is one of the indexes de-scribing the safety state of system.Therefore,Yis the reflection of the result between hazard Hand hazard control C.Ac…
