摘　　要：分析了难以用经典热力学、动力学理论求液体极限温度的原因,指出了三种汽泡形核率公式的异同点及适用条件,分析表明常规沸腾汽泡压力公式及经典汽泡动力学理论因其过多的理想化假设和简化而不适用超急速爆发沸腾。It analyzes why it can't get the limit of liquid superheat by classical thermodynamics and kinetics. It reveals the differences and consistence among three formulas of nucleation rate. It shows the formulas of bubble pressure and classical bubble kinetics in normal boiling can't account for the phenomenon in rapid transient explosive boiling because of too many of those hypothesis and simplification.

关 键 词：爆发沸腾 极限温度 形核率 汽泡压力 汽泡动力学
