中文摘要：

在考虑逃逸速率的情况下采用主方程方法研究分子马达，计算了逃逸速率对分子马达的漂移速率、扩散系数、停留时间以及分子马达在轨道上移动的距离．通过计算发现，逃逸速率影响分子马达的定向运动．

英文摘要：

Master equation is used in the paper under the condition of dissociation rate to study the directed motion of molecular motor. The drift velocity, the diffusion constant, the dwell time and the mean length of the motor are calculated. We found the dissociation rate affects the directed motion of the molecular motor.
