Climate Convention Implementation: An Opportunity for the Pacific Island Nations to Move Toward Sustainable Energy Systems

This article does not focus on adaptation or mitigation policy directly but on an allied opportunity that exists for the Pacific Islands via the auspices of the Climate Convention, because the existing very costly energy systems used in the Pacific Island region are fossil-fuel dependent. It is argued here that efforts can be made towards the development of energy systems that are ecologically sustainable because Pacific Island nations are eligible to receive assistance to introduce renewable energy technology and pursue energy conservation via implementation mechanisms of the Climate Convention and, in particular, through transfer of technology and via joint implementation. It is contended that assistance in the form of finance, technology, and human resource development from developed countries and international organizations would provide sustainable benefits in improving the local Pacific Island environments. It is also emphasized that mitigation of greenhouse gas emissions is not the responsibility of the Pacific Islands as they contribute very little on a per capita global scale and a tiny proportion of total global greenhouse gas emissions.

热辐射的破坏准则和池火灾的破坏半径

热辐射破坏是发生在开放气环境中的池火灾的主要破坏机理。本文讨论了热辐射的破坏准则，提出预测池火灾破坏半径的方法，进行了数值模拟计算，分而和时纳了池火灾的基本规律     

双室火灾烟气特性的实验研究

本文在１／２缩尺建筑模型中，取双室－走廊结构，以标准木垛为火源，对建筑火灾的初始阶段进行了实验模拟。着重研究了火灾初期的烟气特性及其变化，包括烟气温度及烟气中ＣＯ＿２气体和炭颗粒浓度。本文目的在于在探索和发展中等尺寸火灾实验模拟手段和方法的同时，定性地确定火源功率对烟气特性的影响，并积累一定的实验数据，为建筑火灾的分析和模化提供实验基础和依据。     

废水中甲酸萃取回收的研究

以ＺＹＭ混合溶剂为萃取剂，以含４．５％的甲酸的废水进行萃取试验，结果表明，ＺＹＭ具有良好的热稳定性和再生性，对废水中的甲酸有较高的萃取率。采用本萃取技术，不但具有显著的环境效益，而且还可回收甲酸，获得较好的经济效益。
