凝析油储罐运行中的安全问题及改进

据国际国内关于油品储罐的事故统计和分析，拱顶储油罐的事故率最高，可见该类型储罐风险大，由于影响储罐安全运行的因素很多，任何一个环节出问题，都可能引发重大事故。本文就凝析油罐运行6年来，从储罐腐蚀、浮盘质量及安全环保方面所发现和整改的实际情况，在设计和施工中遗留的问题进行深入分析，提出改进措施，为类似的储罐设计施工及管理提供参考。

Significant developments in sustainable development law and governance: A proposal

This article develops a practical proposal for progress on sustainable development law. It examines the prospects for an international sustainable development law to provide a framework for more effective, coherent governance. Sustainable development law is briefly defined and an analytical framework is provided. Different degrees of integration between economic, social and environmental law are described. Certain principles of international law related to sustainable development are also highlighted. It is argued that these principles may serve to guide law‐makers and jurists where social, economic and environmental law and policy conflict or overlap. Continuing, underlying questions of sustainable development governance are addressed and its global frameworks analysed. The article also focuses on the 2002 World Summit on Sustainable Development, held in Johannesburg in August‐September 2002, and its specific mandate for the United Nations Commission on Sustainable Development (UNCSD) to take related legal developments into account. The article advances a proposal: that governments, economic, social and environmental intergovernmental organizations and other actors establish a ‘network of inquiry’ with members from relevant groups, including legal and academic organizations, and other expert groups, in order to follow, research, analyse and debate legal developments in a balanced way.     

TRANSIENT RESPONSE FUNCTIONS FOR CONJUNCTIVE WATER MANAGEMENT IN THE SNAKE RIVER PLAIN,IDAHO1

ABSTRACT: Increasing demands on western water are causing a mounting need for the conjunctive management of surface water and ground water resources. Under western water law, the senior water rights holder has priority over the junior water rights holder in times of water shortage. Water managers have been reluctant to conjunctively manage surface water and ground water resources because of the difficulty of quantification of the impacts to surface water resources from ground water stresses. Impacts from ground water use can take years to propagate through an aquifer system. Prediction of the degree of impact to surface water resources over time and the spatial distribution of impacts is very difficult. Response functions mathematically describe the relationship between a unit ground water stress applied at a specific location and stream depletion or aquifer water level change elsewhere in the system. Response functions can be used to help quantify the spatial and temporal impacts to surface water resources caused by ground water pumping. This paper describes the theory of response functions and presents an application of transient response functions in the Snake River Plain, Idaho. Transient response functions can be used to facilitate the conjunctive management of surface and ground water not only in the eastern Snake River Plain basin, but also in similar basins throughout the western United States.

中美煤矿安全比较与借鉴

中国和美国都是煤炭生产和消费大国,但是中国的煤矿安全却与美国存在巨大差距。笔者首先从两国历年来煤矿安全数据分析入手,认为:美国煤矿安全经历了严重恶化、小幅波动和安全稳定3个阶段;而中国的煤矿经历了改革开放前大起大落和其后的小幅波动两个阶段,迄今为止,还没有进入安全稳定时期。然后从法规、监察、采矿权、安全投入、矿工及工会、教育及培训、科技进步等7个方面对两国的煤矿安全进行了比较。最后,借鉴美国进入第3阶段的成功经验,提出一些改善中国煤矿安全的相应对策建议,如完善法规、加强监管、明晰采矿权、设立安全投入预算资金、改善矿工的弱势地位、加强教育与培训、依靠科技进步等。
