摘要
从非平衡态热力学理论出发，建立了有相变发生时球形气核与围流液体之间能量流和物质流的方程式．在此基础上，确定了自由气核空化初生的条件，并结合气泡动力学对此进行了深入的讨论。
The energy flux and mass flux equations have been established while a liquid vapor phase change occurs on spherical gas nucleus wall on the basis of non equilibrium thermodynamics. The condition of incipient cavitation of free gas nucleus has been derived. Combining with bubble dynamics, the criterion of determining the condition of incipient cavitation has been proposed.
