福建城市化发展战略博士笔谈
2003年5月,“福建省博士创业促进会”在福州举办了福建省城市发展战略“博士月谈”,与会者主要是省内高校和科研单位的专家、博士。会上,大家用书面发表意见,畅所欲言,崇论宏议。本刊精选部分意见,以飨读者。相信这些意见对福建城市化问题研究的深化将起到积极的推动作用
a context-aware framework for mobile and pervasive applications
蕴涵着高度动态变化特性的移动和普适计算环境给分布式系统的设计提出了新的挑战,上下文感知框架汇聚了感知和处理各种易变因素的基础设施.依托框架开发移动和普适应用,能加快开发速度,提高应用程序的健壮性.本文分析了各种上下文信息及其作用,给出了上下文感知框架XAF的设计,探讨了框架中的关键技术,包括上下文转换和服务自适应选择
Review of flow and heat transfer of supercritical carbon dioxide
This paper gives a review of the heat transfer and pressure drop characteristics of supercritical carbon dioxide in-tube flow.Some published correlations for heat transfer coefficient and pressure drop during in-tube cooling are collected.The accuracy of the correlations are discussed through comparing the calculation results with the experimental data.The shortages of current researches are pointed out
Review on Heat Transfer of Subcritical Carbon Dioxide
This paper gives a review of the heat transfer characteristics of subcritical carbon dioxide in-tube flow. Some published correlations for heat transfer coefficient during in-tube flow are collected. The accuracy of the correlations is discussed through comparing the calculation results with the experimental data. The applicable correlations in different conditions are recommended
