| Summary: | 碩士 === 國立中央大學 === 物理研究所 === 95 === Polymer physics is a very important subject whose application can be found in various, which are both materials as well as in biological machinery. The purpose of this research is to investigate the dynamical properties of a polymer chain. We use the dynamical models of a polymer chain consider a polymer under different kinds of an oscillatory external drives in a structure and dynamics of a solution. Our purpose is to understand how the polymer chain are affected by the external oscillatory drive.
In this thesis, we consider a polymer chain under different oscillatory drive and frequencies, and calculate how polymer chain is being elongated, and try to obtain the condition that the chain is maximally elongated. Furthermore, the dynamic behavior
of polymer chain, such as the relaxation time, and how it is related to the external drives are investigated.
