摘要
本文将体视学关系式分成基本公式、基于特别设计的无偏统计取样策略的关系式及基于模型的关系式。后一类关系式的可靠性强烈依赖于所用模型与所研究组织的接近程度。借助于改进的MonteCarlo方法,本文建立了一类比单一形状晶粒经典模型和随机几何模型更接近实际材料的三维晶粒组织仿真模型。
In the present paper, stereology are classified into the basic equations, the relations based on unbiased sampling principle which is specially designed, and the relations based on model(s). The rationality of the last category strongly depends on the degree of the similarity between the model and the structure researched.By means of the modified Monte Carlo method, a threedimensional simulation model nore realistic than the classic singleshaped grain models and stochastic geometric models was built.Through threedimensional measurement on the simulated structure, it is expected to further improve the previous modelbased stereological calculation method for grain size distribution.
