摘要
文章为目前国际矿相学界通用的两种标准白色光源(A和C光源)以及等能光源提供了一套求解矿物颜色主波长和饱和度的新检索数据表。利用该表解法可以脱离色品图,并具有简单快速、准确可靠的优点。此外,还为A和C两种标准光源提供了一套饱和度值从0.2%～100%的色品图。
In this paper,an new deterrninative table for the dominant wavelength λ_d and the excitation purity P, of the reflection colour of ore minerals is given. It is relative go the C. I.E. standard illuminant A and C as well as the theoretical ideal white light. This new tabular method,without the help of chromaticity diagram, is simple, rash and accurate.In addition ,series of chromaticity diagrams with various P, values(0.2～100) are presented.
