摘要：应用图像分析仪和定量体视学原理，对颗粒群特征参数进行了定量分析，并对图像分析的实验参数：最小样本数、图像优化及灰度阈值等进行了讨论研究。实验结果表明，定量体视学图像分析方法可同时获得煤矿渣细粉试样的级配和颗粒形状因子（圆度）等一系列颗粒群特征参数。

Abstract：Based on the quantitative stereology theory, the quantitative characteristics of particle group such as particle size distribution, roundness are determined by using image analysis.The experiment parameters of quantitative stereology theory such as minimum samples, grey threshold are also studied.The experiment results show that the characteristics of 3Dmicrostructure can be precisely obtained by using the theory of quantitative stereology and the method of image analysis, and the results have higher reliability.
