本文应用统计热力学巨正则系综的密度涨落理论;提出了确定均质凝结中蒸汽极限过冷度的方法,得出了蒸汽凝结机制较沸腾机制复杂得多的结论,并推测出动力学影响是蒸汽凝结不可忽略的重要因素。
In this paper, the density fluctuation theory of the giant canonical ensemble of statistical thermodynamics is applied. A method to determine the ultimate supercooling degree of the steam in the homogeneous condensation is proposed. The conclusion is drawn that the steam condensation mechanism is much more complex than the boiling mechanism. Steam condensation can not be ignored important factor.
