给出了单组分成核中簇的生长和衰变概率的精确和近似通用表达式。提出了一种借助簇生长概率对簇大小的依赖性的数据来独立于模型确定核大小的方法。获得了 Lennard-Jones 蒸气中液滴的均匀单组分成核的团簇生长概率的蒙特卡罗模拟数据。根据这些数据，新提出的方法确定了核液滴的大小和 Zeldovich 因子。
Exact and approximate general expressions for the growth and decay probabilities of a cluster in one-component nucleation are given. A method is proposed for a model-independent determination of the nucleus size with the help of data for the dependence of the cluster growth probability on the cluster size. Monte Carlo simulation data for the cluster growth probability are obtained for homogeneous one-component nucleation of droplets in Lennard-Jones vapors. From these data, the size of the nucleus droplet and the Zeldovich factor are determined by the newly proposed method.
