Based on an analogy between polymer translocation across a free energy barrier associated with polymer worming through a hole and classical nucleation and growth process, the escape time tau is predicted asymptotically to be N(N/rho)(1/3nu). N is the polymer length, rho is the monomer density prior to escape, and nu is the radius of gyration exponent. Monte Carlo simulation data collected in the high salt limit (nu approximately 3/5) are in agreement with the asymptotic law and provide vivid details of the escape.
基于聚合物通过与聚合物蠕变穿过孔洞相关的自由能垒的转移与经典成核和生长过程之间的类比，逃逸时间τ被渐近预测为N(N/ρ)^(1/3ν)。N是聚合物长度，ρ是逃逸前的单体密度，ν是回转半径指数。在高盐极限（ν约为3/5）下收集的蒙特卡罗模拟数据与渐近定律一致，并提供了逃逸的生动细节。
