本文研究了刚性聚合物在小管内拉伸时的力-拉伸行为。基于最近发展的广义珠棒模型(GBR)，我们发展了一种理论并进行了布朗动力学模拟，表明这种强受限高分子链的力-伸展关系可以用基于Odijk的受限高分子链理论的有效力作用的非受限高分子链的力-伸展关系来描述。
The present paper investigates the force-extension behavior of a stiff polymer under stretching inside a small tube. We develop a theory and perform Brownian dynamic simulations based on a recently developed generalized bead-rod model (GBR) to show that the force-extension relation of such a strongly confined polymer chain can be described by that of an unconfined polymer subject to an effective force which is derived based on Odijk’s theory of a confined polymer chain.
