金属矿物切面形状的定量表征及其意义

NUMERICAL DESCRIPTION FOR CUTOFF FORM OF ORE MINERAL GRAINS AND ITS IMPLICATION

在矿相学研究中,综合运用圆形度、表面指数和本文所建立的凹陷度等形状因子,能够定量表征金属矿物的切面形状,定量对比矿物间的晶形差异。根据形状因子曲线圈,可以较准确地了解所研究矿物晶形的总体特征。从而弥补定性描述矿物形状的不足。

In this paper several form factors for numerically specifying the cutoff forms of ore mineral grains under micrascopy are postulated. With these form factors and factor-diagrams,one can digitize the cutoff forms of mineral grains and then compare them quantitatively. This is significant for ore-microscopic research.
