本文简要介绍了体视学在定量金相学上的应用。应用体视学的基本公式,把二维平面上测量得到的显微特征,经过统计处理,从而推算出三维的组织形态。并对晶粒大小测定、多相合金中各组成相相对量测定,以及粒子间距测定的统计方法作了介绍。 This article briefly introduces the application of stereology in quantitative metallography. The basic formula of stereology is applied to calculate the microscopic features measured on the two-dimensional plane through statistical processing to deduce the three-dimensional tissue morphology. The methods of determining the grain size, determining the relative amounts of the various phases in the multiphase alloy, and the statistical methods for measuring the particle spacing were introduced.
