得到了一个新的稳态形核通量的渐近表达式。该结果提供了Zeldovich经典表达式的非平凡推广，并且具有更广泛的适用范围。对于极高的过饱和度，当临界团簇数不超过几个单位时，成核速率的指数前表现出振荡行为。后一种效应对于具有高界面张力的系统增加。
A new asymptotic expression for the stationary nucleation flux is obtained. The result provides a nontrivial generalization of the classical expression attributed to Zeldovich, and has a much broader domain of applicability. For extremely high supersaturations when the critical cluster number does not exceed a few units, the preexponential of the nucleation rate exhibits an oscillatory behavior. The latter effect increases for systems with high interfacial tension.
