摘要

Based on a simple model of soliton-like conformational switchings in two-component bistable polymer molecules with energetically non-equivalent stable states, this paper presents the dependence of the dynamics of conformational switchings on the parameters of nonlinear longitudinal excitation (degree of stretching, propagation velocity along the molecular chain). It has been demonstrated that under certain conditions the longitudinal excitation can act as a trap for a conformational switching and, as a consequence, can determine the conformational switching dynamics.
