摘　　要：对复相材料二维截面中第二相的空间分布状况的多级判别的模式识别方法作了较全面的综述，并对第二相的三维空间分布状况的一些体视学观测研究方法，尤其是近年来发展的新方法作了较为系统的介绍．指出在实际材料微结构设计和性能预测的过程中，应针对所研究的具体的材料特点、具体的机械性能类型以及材料性能力学计算工作的需求来确定恰当的描述尺度，选择合适的描述方法，以确定夹杂物或第二相的空间分布对材料机械性能的定量影响，尤其应注意发挥体视学在其中的重要作用．This paper presents a comprehensive review of description methods for the spatial distribution of the second phase in multi-phase materials. Stereological methods, especially, some new methods developed lately for description of three-dimensional distribution, are discussed. In order to get quantitative relationships between the spatial distribution of the second phase and material properties, it is necessary to select proper spatial scales and description methods to evaluate the distribution, according to specific material properties under investigation, as well as to use the computational simulation for material properties. Particular, attention should be paid on the important role of stereology.
