摘要

蠕虫状链是一种适用于从柔性到刚性的大分子链模型, 尤其适合半刚性和刚性高分子链, 因此运用此模型分析多肽与 DNA 等生物大分子链构象的研究越来越多. 在简单介绍蠕虫状链模型的基础上, 分析了运用蠕虫状链模型推导均方末端距时存在的问题, 并提出了采取自由旋转链模型处理的解决方法, 有助于正确理解与应用蠕虫状链模型.

Abstract

Wormlike chain is a popular model for biological macromolecules such as DNA, and for semi-rigid and rigid-chain polymers. This paper discusses the worm-like chain model, especially the mistake in the derivation of end-to-end distance, and suggests an effective solution using a free rotation chain model. It is helpful for using the wormlike chain model correctly.
