摘要
在前人工作的基础上提出了表征核态池沸腾中气泡脱离和生长过程的特征时间和特征尺度，并进而得到了气泡生长时间和气泡脱离直径的通用关系式，应用传热学类比方法建立了计算气泡脱离直径的一般公式。本文的研究结果与前人的实验结果甚为相符。
On the basis of currently available study results this paper introduces a characteristic length scale and time scale to describe the dynamic growth and departure process of bubbles in nucleate boiling. A general correlation between bubble departure diameter and bubble growth time is thereby obtained. Through the use of heat transfer analogous method a general formula has been worked out to calculate the bubble departure diameter. The study results of the present paper are in full agreement with experimental ones provided by other researchers.
