摘要
对现有汽-液相变过程有关文献中关于汽泡形成过程的分析提出了不同看法,并利用热力学理论从亚稳平衡态的特性出发对汽泡形成的热力学机制作出了分析,对系统从液态转变到汽-液共存状态的各阶段作出了说明。
In the present paper a distincted viewpoint and understanding about theliquid-vapor phase transition process is proposed which is different from that in some of the existingarticles.The thermodynamic mechanism of the formation of bubbles is in vestigated from theviewpoint of the charateristics of the metastable equilibrium states in accordan ce withthermodynamic theory,The stages of state transformation of the systeml from the pure liquid to thellquid-vapor coexisting states are discussed in detail.By this way the explanation on the physicalessence of the liquid-vapor phase transition process and its cor rect description are thus provided.
