摘　　要：变形金属位错链长度统计分布理论是现代金属塑性变形定量微观理论最活跃课题之一。该研究的开展将会在钢铁等金属材料的微观结构与宏观力学性能之间建立一座桥梁,揭示其内在联系和演变规律,给出符合实际情况的定量结论。本文分理论和实验两部分系统介绍了它的发展、研究特色、方法及最近结果。对目前存在问题及值得探讨的方向也作了初步评述。The theory of statistical dislocation link length distribution is an active field in the modern microscopic quantitative theory of metal plastic deformation. The development of this theory would make a bridge between microstructures and micromechanical properties of metallic materials. The quantitative conclusions which accord with the demands can be obtained from the theory by revealing their internal relations and change laws. In this paper its development, feature, methods and the present research work were systematically introduced by two parts: theory and application. The existing problems and the future of the theory were discussed as well.
