研究了熔化温度、Tm、最大晶化温度、晶体生长速率最大的Tcmax和玻璃化转变温度Tg的经验先验规律，以寻找唯象和理论背景。根据等体积状态模型和结晶理论，建立了Tm、Tcmax和Tg之间的关系式：Tcmax Tm=C(C+1)和TgTm=(C−1)(C+1)。一般情况下，C在3~9之间变化，平均值在5左右，即TgTm的比值在1 2~4 5之间变化，平均值为2 3；Tcmax的比值在3 4~9 10之间变化，平均值为5 6。
Empirical prior rules in melting temperature, T m, maximum crystallization temperature, T cmax, at which crystal growth rate is maximum, and glass transition temperature, T g, were investigated to find a phenomenological and theoretical background. Relationships among T m, T cmax and T g were formulated as T cmax T m= C (C+ 1) and T g T m=(C− 1)(C+ 1) on the bases of an iso-volume state model and a crystallization theory. In general, C varies from 3 to 9 and the mean value is about 5. That is, the ratio of T g T m changes from 1 2 to 4 5 and the mean value is 2 3. The ratio of T cmax T m changes from 3 4 to 9 10 and the mean value is 5 6.
