孔板流量计计量误差现场因素分析

结合现场实际,从气体组分和气体质量、孔板、配套管路和测量仪表、流量计算中各常数等四个方面,对采用标准孔板的长距离天然气管道流量计量系统正负误差的产生原因进行了分析,并结合运行实践,提出了运行中应注意的问题,为提高计量准确度和误差综合分析提供了参考。     

我国石油天然气会计准则国际趋同分析

为规范石油天然气行业特殊的交易或事项，美国等国家和国际会计准则理事会（IASB）都发布了专门的石油天然气会计准则或采掘业会计准则。我国于2006年2月发布了《企业会计准则第27号一石油天然气开采》会计准则，对当前我国石油天然气开采业财务会计发展中的热点、难点问题进行了规范。本文通过对比分析油气新准则与美国FASB制定的相关准则和国际财务报告准则第6号（IFRS6）的差异，认为我国油气新准则基本实现了与美国相关准则的趋同，但与IFRS6还需要多方面的协调。

论强化市场型政府及其制度安排

既要创造和保护私人财产权又要使私人权利不受到侵犯是强化市场型政府的基本内涵.强化市场型政府是社会经济发展中关于政府的一种理想模式.建立强化市场型政府是完善我国社会主义市场经济体制的需要.民主制度与法治化社会是建立强化市场型政府的基本前提条件.从制度安排入手建立我国强化市场型政府要实现三个转变:从自然政府到强化市场型政府的转变;从保护精英阶层的产权到保护全社会产权的转变;从人治社会向法治社会的转变.     

Thermoeconomics: Beyond the Second Law

Physicist Erwin Schrödinger's (1945) What is Life? has inspired many subsequent efforts to explain biological evolution, especially the evolution of complex systems, in terms of the Second Law of Thermodynamics and the concepts of ‘entropy’ and ‘negative entropy’. However, the problems associated with this paradigm are manifold. Here some of these problems will be highlighted and briefly critiqued. ‘Thermoeconomics’, by contrast, is based on the proposition that the role of energy in biological evolution should be defined and understood not in terms of the Second Law but in terms of such economic criteria as ‘productivity’, ‘efficiency’, and especially the costs and benefits (or ‘profitability’) of the various mechanisms for capturing and utilizing available energy to build biomass and do work. Thus thermoeconomics is fully consistent with the Darwinian paradigm. Economic criteria provide a better account of the advances (and recessions) in bioenergetic technologies than does any formulation derived from the Second Law.

Encouraging Environmentally Sustainable Growth: Experience in OECD Countries

This paper presents an overview of OECD analysis of progress and policies in ``enhancing environmentally sustainable growth' in a number ofcountries. The focus of the paper is on how countries succeed in conducting cost-effective and consistent policies in the environmental and natural resource areas, not on environmental policy or outcomes per se. The chapters were tailored to focus on a small number of interesting or important themes in each country, rather than aiming at a comprehensive coverage. Four common themes nevertheless emerged: a definite trend in recent years towards the use of market-based instruments; competitiveness and distributional issuesas obstacles to policy implementation; certain sectors where policies make environmental objectives harder or more costly to achieve; attempts to design institutions or processes to achieve co-ordination across policies and sectors. These arediscussed and illustrated in turn in the paper.
