摘要：
Thermal production of soliton-antisoliton pairs in an overdamped driven sine-Gordon chain occurs through the activation of a critical nucleus. The relevant pair nucleation rate is calculated explicity by extending Kramers' theory to the case of an infinite dimensional, multistable system with one neutral equilibrium mode.
