解析降温结晶速率常数的一种新方法

A new method to obtain the rate constant by cooling crystallization

推导了一种解析降温结晶速率常数的新方法，运用Monte Carlo方法模拟PET降温结晶过程，并用新方程处理了模拟所得结晶相关数据。结果表明：在Awarni指数n确定的情况下，将结晶速率常数K（T）看作Gaussian函数时所得的非等温微分方程可以很好的解析降温结晶过程。

An equation to obtain the rate constant by cooling crystallization was educed. The Monte Carlo method was used to simulate the cooling non-isothermal crystallization of PET. The data derived from simulated process was dealed with this equation. The result shows that the differential equation for non-isothermal crystallization can be used to analyze the cooling non-isothermal crystallization quite well in case that K（T） is considered to be the Gaussian form and the Avrami exponent n is confirmed.
