萃取分光光度法测定工业废气中的游离溴

用萃取分光光度法测定工业废气中的游离溴，并对样品的采集与保存，萃取条件的选择进行了研究。结果表明，当溴的含量在１８．０－４５０．０μｇ／ｍＬ范围同时，吸光度与浓度具有良好的线性关系，方法的采样效率大于９９％，精密度和准确度较好当采集气体为１００Ｌ时，最低检出肖度为０．１４ｍｇ／ｍ＾３。

Life cycle analysis and choice of natural gas-based automotive alternative fuels in Chongqing Municipality,China

Road transport produces significant amounts of emissions by using crude oil as the primary energy source. A reduction of emissions can be achieved by implementing alternative fuel chains. The objective of this study is to carry out an economic, environmental and energy (EEE) life cycle study on natural gas-based automotive fuels with conventional gasoline in an abundant region of China. A set of indices of four fuels/vehicle systems on the basis of life cycle are assessed in terms of impact of EEE, in which natural gas produces compressed natural gas (CNG), methanol, dimethylether (DME) and Fischer Tropsch diesel (FTD). The study included fuel production, vehicle production, vehicle operation, infrastructure and vehicle end of life as a system for each fuel/vehicle system. A generic gasoline fueled car is used as a baseline. Data have been reviewed and modified based on the best knowledge available to Chongqing local sources. Results indicated that when we could not change electric and hydrogen fuel cell vehicles into commercial vehicles on a large scale, direct use of CNG in a dedicated or bi-fuel vehicle is an economical choice for the region which is most energy efficient and more environmental friendly. The study can be used to support decisions on how natural gas resources can best be utilized as a fuel/energy resource for automobiles, and what issues need to be resolved in Chongqing. The models and approaches for this study can be applied to other regions of China as long as all the assumptions are well defined and modified to find a substitute automotive energy source and establish an energy policy in a specific region.     

Human adaptation to climate change: a review of three historical cases and some general perspectives

To study mitigation and adaptation to climate change, social scientists have drawn on different approaches, particularly sociological approaches to the future and comparative history of past societies. These two approaches frame the social and temporal boundaries of decision-making collectivities in different ways. A consideration of the responses to climate variability in three historical cases, the Classic Maya of Mexico and Central America, the Viking settlements in Greenland, and the US Dust Bowl, shows the value of integrating these two approaches.     

试论我国环境行政强制执行制度

环境行政强制执行制度是环境执法的重要制度。大陆法系国家实行德奥模式而从法律上确立环境行政机关强制执行地位，英美法系国家一般实行美法模式而以诉讼方式实现环境行政强制执行，日本则有更为严格、完善的环境行政强制执行制度。比较上述模式后认为：基于我国国情，法律应赋予环境行政机关一定的直接强制执行权，明确环境行政强制执行与司法强制执行的权限，确立环境行政强制执行制度。
