高压下链状均聚物的状态方程

Equations of State for Chain Homopolymers in High Pressure

在似谐振子模型的基础上，获得了一个状态方程。在高压下计算值能很好地与实验值一致，并在广泛的温度范围内成立。结果表明，对于链状均聚物，链节运动对压力的贡献比链节之间相互作用对压力的贡献大，两者近似地存在一个简单的比。

This paper gives a set of equations of state for chain homopolymers on the ba-sis of the quasi-harmonic osciltator model.The calculation results are in good agreementwith the experiment in high pressure and wide temperature range. The results showed thatthe contribution of mers motion for pressure is larger than that of mutual interaction amongmers,and there is a simple ratio between them.
