摘要
借助似谐振子模型和统计方法,对玻璃态链状均聚物作了一般讨论,并推出比热和线膨胀系数的一般表达式。最后,以PS为例,把理论值与实验值作了比较,结果是令人满意的。
This paper gives the general discussion for chain homopolymers by quasi-harmonic oscillator model and statistical method. It obtain an expression of coefficient of linear expansion. The values of calculation are in good agreement with experiment values. The result is satisfying.
