液相-玻璃相转变的渗流模拟中的双曲线近似

A hyperbola approximation approach in the percolation model of the liquid glass transition

借助自由体积理论中的渗流模拟描述液相玻璃相转变；采用双曲线近似将两相转变过程非线性化，并考虑平均淬火速率Ｔ·的影响，求得液相统计权Ｐ（Ｔ，Ｔ·）；最后具体讨论了聚醋酸乙稀酯的液相玻璃相转变。

By using the free volume approach and percolation theory,the liquid glass transition has been studied.Adopt the nonlinear hyperbola approximation and concerned with the effect of the overage quenching speed T· ,the liquid statistical wieght P(T,T·) is obtained.Finally,as an enample,the liquid glass transition of polyviny lacetate (CH 2OHOOCCH 3) is discussed and it's P T curves corresponding to a certain T· are obtained.
