Analysis of Numerical Results in High Temperature Congealment and Chemistry Non-equilibrium Flow Field

Using the air plasma ignition technique, physicochemical process of burning can be accelerated; concentration limit ofretrofires both can be extended; reliability of retrofires and stability of burning can be improved. In this paper, using internalequivalent heat area in place of electric are that created Ohm heat, the flow fields of thermodynamic equilibrium chemistry con-gealment and chemistry non-equilibrium in the plasma generator were simulated. The influences of the inlet prerotation angleof air, the inlet total pressure of air and the airflow compression angle of spray nozzle on the temperature on the surface of elec-

港口供需匹配非均衡评价模型及实证

港口供需匹配是港口发展核心问题之一,在当前我国对外贸易转型升级大背景下,港口供需是否匹配均衡对于提升我国港口运营效率、节约港口资源等具有重要现实意义。本研究在借鉴文献[14]的基础上,利用非均衡分析理论和模型进一步深入评价港口供需匹配情况:一是构建了供给、需求和共性三维度的港口供需匹配评价指标体系,二是建立了改进和优化的港口供需匹配非均衡评价模型。三是采集2006-2013年上海港数据分析,结果表明:上海港2006-2013年期间潜在供给小于潜在需求、处于严重或轻度供给不足状态,但供给需求缺口逐年收窄,较符合上海港实际运营客观现状。
