摘　　要：对近年来发展的双截面体法、点取截距法、点取面积法、择合法等与传统的系列截面法进行了比较性研究分析，并实际应用于一种微合金化低碳钢奥氏体晶粒尺寸及拓扑分布的定量测估。证实了有关方法在材料科学领域中的可行性。The basic methods for measurement of three dimensional grain size and topological distributions were outlined, including the conventional serial section analysis and the newly developed disector, selector, point sampled intercehts and point sampled areas. With a practical application in a low carbon steel, the feasibility of these methods for unbiased and efficient evaluation of size and topological distribution parameters of space filling grains was demonstrated.
