Thermodynamics provides a driving force to molecules of plastic to reorient themselves to the most energetically favorable configuration of the molecules.

热力学提供了动力使塑料分子重新调整自己使其达到最有利的形状。

However, a kinetic factor, which determines the speed with which the molecules change their configuration to the most favorable, is largely-in fact, exponentially-dependent on temperature.

然而，动力学因素，它决定了分子达到其最有利的形状的速度，事实上，指数依赖与温度。
