1Integrated simulation of the dualistic water cycle and its associated processes in the Haihe River Basin显示文摘Water resource shortages, water environmental deterioration, and water ecological degradation are becoming increasingly prominent in the Haihe River Basin under the effects of global climate change and intense human activity. Finding ways to solve these problems reasonably is an urgent task in basin water resources management. The water cycle describes the formation and transformation of every water drop, while it interacts with associated water ecology and water environment processes. Therefore, to fundamentally solve the above problems, the three processes must be combined and the evolutionary trends of the ecology and water environment driven by the water cycle must be determined. To comprehensively diagnose and solve the problems of water resources, ecology and water environment in the basin, an integrated simulation platform of the dualistic water cycle and its associated processes in the Haihe River Basin was established by fully analyzing the 'natural-social' dualistic characteristics of the evolution of the basin water cycle in this study. Accordingly, it is a supporting tool to evaluate the future trends of water resources, ecology and the water environment by setting scenarios based on the predictions of a climate mode and water control conditions. The results show that with climate change, the water consumption, groundwater overexploitation, and the amount of water flowing to the sea could develop soundly and satisfy the requirements of national economic growth in the future planning year 2030 through the implementation of water consumption control management and the South-North Water Diversion Project. Meanwhile, associated water environmental deterioration can be alleviated, and a growing trend for production capacities of the natural ecosystem and agro-ecosystem is seen. The above results provide a foundation for implementing basin water resources regulation and the most strict water resources management.WANG Hao JIA YangWen YANG GuiYu ZHOU ZuHao QIU YaQin NIU CunWen PENG Hui 2013Chinese Science Bulletin2013,58,27:10
2Integrated simulation and assessment of water quantity and quality for a river under changing environmental conditions显示文摘The water cycle and water resources within river basins under changing environmental conditions undergo profound changes, which have significant effects on the water environment of the river. Owing to the water resources demanded for economic and social development, water quantity and quality are becoming the core constraints of water resources development and utilization. In this paper, the dual attributes of water resources, progress into research regarding water quantity and quality joint assessment and simulation and the shortcomings associated with these techniques are summarized and described with respect to water quantity and quality. The results indicated that under the current environmental conditions, the method used for traditional water quality assessment of single water bodies cannot meet the requirements for water resources management. Moreover, a coupled hydrodynamic and water quality numerical model for river networks and lakes that applies to the river water environment system was developed for the river network flow and pollutant migration and transformation process and validated. This validation revealed that the error between the simulated values calculated by the model and the monitored values was small, meeting the application requirements and realizing the integrated and dynamic simulation of water quantity and quality of the river water environmental system. On this basis, the integrated simulation model was applied to the Luanhe River Basin.WANG JianHua XIAO WeiHua WANG Hao CHAI ZengKai NIU CunWen LI Wei 2013Chinese Science Bulletin2013,58,27:7

7Technologies for extracting lipids from oleaginous microorganisms for biodiesel production显示文摘最近, biodiesel 收到了更多注意。大豆油,油菜籽油,手掌油和玉米油是为 biodiesel 生产的主要化工物品。然而,从这些传统的充满油的庄稼的 biodiesel 生产由陆路被限制可获得性,气候,和关于使用的环境、社会的问题喂并且为燃料的食物庄稼。产油的微生物,包括微水藻,细菌,酵母和真菌能与高类脂化合物内容被栽培并且为 biodiesel 用作有希望的化工物品生产。然而,高度 biodiesel 生产使用花费了油微生物是为它的工业化的最大的障碍。从微生物的 biodiesel 生产的过程包含许多步,类脂化合物抽取是最重要、昂贵。因此,寻找一个有效、节俭的抽取系统是批评的。类脂化合物抽取的各种各样的途径在这评论被讨论,包括象溶剂抽取那样的传统的抽取过程,压并且溶剂综合抽取,以及某新过程。Cunwen WANG Lu CHEN Bajpai RAKESH Yuanhang QIN Renliang LV 2012Frontiers in Energy2012,6,3:1
8Direct synthesis of diphenyl carbonate over heterogeneous catalyst: effects of structure of substituted perovskite carrier on the catalyst activities显示文摘The perovskite-type compound LaMnO_(3) was substituted for the part of La in position A and for the part of Mn in position B by citrate method.The phases were detected by X-ray diffraction.Powder morphologies were scanned by scanning electron microscopy.The valence of atoms was determined by X-ray photoelectron spectroscopy.It was found that the perovskite can form crystal defect and increase the proportion of high valence B element by doping.Active component Pd was loaded on various perovskite supports for synthesis of diphenyl carbonate.The results showed that the activities of catalysts in which supports have crystal defect by substitution were higher.It can be concluded that perovskite with defect structure by doping could lead to the formation of oxygen vacancy where the lattice oxygen became exchangeable with the oxygen gas.Also,this improved the redox process of the carrier by transferring electrons and activities of catalysts.WU Guangwen WU Yuxin MA Peisheng JIN Fang ZHANG Guangxu LI Dinghuo WANG Cunwen 2007Frontiers of Chemical Science and Engineering2007,1,1:1
