对物理过程的连续基本步骤之间缺乏局部热化的情况下的快速相变进行了分析处理。非马尔可夫主方程是针对快速过程导出的，在高度非平衡系统的快速相变或冻结过程中没有足够的时间达到能量或动量热化。这些主方程为先前在快速相变分析中使用的相场模型的演化和输运方程提供了进一步的物理基础。
Fast phase transitions under lack of local thermalization between successive elementary steps of the physical process are treated analytically. Non-Markovian master equations are derived for fast processes, which do not have enough time to reach energy or momentum thermalization during rapid phase change or freezing of a highly nonequilibrium system. These master equations provide a further physical basis for evolution and transport equations of the phase-field model used previously in the analyses of fast phase transitions.
