The comparison with the method of usual lagrange analysis shows that the method is convenient and accurate in calculating the histories of particle variabes in inertmedium.
With a suitable thermodynamics model, a simulation was taken to investigate the effects of various fraction of various inertmedium on the heat properties of polymerization system.
通过选用合适的热力学模型，模拟计算了不同种类的冷凝介质，不同组成分率对聚合体系物性的影响。
