沸腾系统是一个典型的开耗散结构。从非平衡态热力学出发，导出了沸腾模式转变的判据。发现不同沸腾状态之间的转变对应于热力学第一分岔和热力学第二分岔：系统发展趋向于最小化熵生成。从动力学角度揭示了活性位点或干斑之间相互作用导致的不同沸腾模式之间的自组织转变过程，从而形成沸腾耗散结构。本研究不仅从理论上解释了其他研究者的实验观察结果，而且对不同沸腾模式之间转变的本质有了更深入的了解。
Boiling system is a typical open dissipative structure. The criterion for the transition of boiling modes is derived based on non-equilibrium thermodynamics. It is found that the transitions between different boiling regimes correspond the first thermodynamics bifurcation and second thermodynamics bifurcation: system develops tending to minimize the entropy generation. The self-organized transition processes among different boiling modes caused by the interactions among active sites or dry patches that result in the formation of boiling dissipative structure are then revealed from dynamic perspective. The present studies not only theoretically explain the experimental observations from other researchers, but also give deeper insight on essences of the transitions between different boiling modes.
