摘　　要： 对池沸腾传热现象局部传递过程的细致分析(例如微重力池沸腾传热研究文献中关于热毛细效应作用及其成因的各种相互冲突的观点),涉及汽液相变界面两侧的间断关系。相变(蒸发或凝结)过程的非平衡性导致相界面两侧物理量对经典平衡态热力学中的相界面关系的偏离,分子动理论比拟模型、统计率模型和非平衡热力学模型均给出了相关描述,本文对此进行了详细评述,指出了各模型的优缺点,并对进一步的研究方向进行了讨论。 Detailed analyses of local transport phenomenon of boiling heat transfer, such as viewpoints at the origin and influence of the Marangoni effect in the literature which are contrary with each other, come down to the jump conditions across the interface with phase change. Non-equilibrium of evaporation and/or condensation phase changes results in the deviation of the relationship about interface deduced based on the classical equilibrium thermophysics. Some existed correlations in the jump conditions across the vapor-liquid interface with phase changes, including kinetic analog model, statistical rate model and non-equilibrium model, are reviewed in detail. Their merits and demerits are analyzed, while some new directions for further study are highlighted.
