摘　　要：本文简要概述了沸腾传热类型和沸腾传热曲线,分析探讨了影响核态沸腾传热的主要因素及核态沸腾传热模型,讨论了形成汽泡核所需的液体过热度、汽泡的生长,汽泡的脱离直径、汽泡的脱离频率及汽化核心密度等汽泡动力学规律。This paper gives a brief outline of types and typical curve of boiling heat transfer. The major factors influencing nucleate boiling heat transfer and models of nucleate boiling heat mechanism have been discussed. In addition, the research status of bubble dynamics in nucleate boiling including liquid superheat forming bubble nucleus, bubble growth, departure diameter and departure frequency as well as nucleation site density has also been introduced.
