同相成核是指在整个转变过程中，当这些晶体的组成与其基体相不同时，在同一相晶体的相间边界处析出晶体的成核。在简要介绍这一现象的发现和解释之后，描述了确定交感神经成核存在的方法。交感神经成核所产生的最常见的形态形态被描绘出来。然后应用异相成核理论来解释交感成核。特别强调交感核成核的驱动力，因为相图几何和过饱和对交感核成核的许多影响可以在此基础上简单地解释。
Sympathetic nucleation is defined as the nucleation of a precipitate crystal at an interphase boundary of a crystal of the same phase when these crystals differ in composition from their matrix phase throughout the transformation process. Following a brief history of the discovery and interpretation of this phenomenon, the means of identifying the presence of sympathetic nucleation are described. The morphological configurations most frequently produced by sympathetic nucleation are illustrated. Heterogeneous nucleation theory is then applied to explain sympathetic nucleation. Particular emphasis is placed upon the driving force for sympathetic nucleation, since many of the effects of phase diagram geometry and supersaturation upon sympathetic nucleation can be simply explained upon this basis.
