DNA非线性激励的简单组合模型

Simple Combined Model for Nonlinear Excitations in DNA

D. L. Hien, N. T. Nhan, V. Thanh Ngo, N. A. Viet

摘要:

基于Englander \cite{A1}的钟摆模型和Peyrard { \it et al.}的微观模型,提出了一个新的DNA变性的简单模型,\cite{A3}所谓的“组合模型”。模型的主要参数为:链间的耦合常数$k$、氢键的平均伸展量$y^\ast$、阻尼常数与驱动力之比$γ/F$。我们证明了不成对碱基的长度$L$和扭结的速度$v$不仅依赖于耦合常数$k$,而且依赖于温度$T$ .我们的结果与以前的工作是一致的。

英文摘要:

We propose a new simple model for DNA denaturation bases on the pendulum model of Englander\cite{A1} and the microscopic model of Peyrard {\it et al.},\cite{A3} so called "combined model". The main parameters of our model are: the coupling constant $k$ along each strand, the mean stretching $y^\ast$ of the hydrogen bonds, the ratio of the damping constant and driven force $γ/F$. We show that both the length $L$ of unpaired bases and the velocity $v$ of kinks depend on not only the coupling constant $k$ but also the temperature $T$. Our results are in good agreement with previous works.
