讨论了有序-无序转变的弛豫问题。讨论了非平衡态的热力学势，引入了有序-无序变化的亲合势。熵产生用序参量表示。因此，沿着非平衡态热力学的Prigogine-de Groot理论，得到了序参量和熵随时间的变化。结果表明，在恒温有序形成和衰变的早期阶段，短程有序参数和产生的熵随时间呈线性变化。
The relaxation of order-disorder transition has been treated. The thermodynamic potential of a non-equilibrium state is discussed, with the affinity of order-disorder change being introduced. Entropy production is written in terms of order parameters. Thus along the line of the Prigogine-de Groot theory in non-equilibrium thermodynamics, time variations of order parameters as well as those of entropies are obtained. It is shown that, in the early stages of both the formation and decay processes of order at constant temperature, the short-range order parameter and the amount of produced entropy vary linearly with time.
