| 摘 要： | 本文给出了30个菱镁矿-菱铁矿的化学成分和红外吸收频率。实验资料表明,随着矿物中Fe含量的增加,相应红外带的频率有规律地向低频方向移动,二者间有着密切的相关关系。对于ν2-Fe/(Mg Fe)的相关性,用最小二乘法得到的一元线性回归方程为:Y=880.7-0.1450X 相关系数 r=0.9690。

| Abstract: | Presented in this paper is the infrared spectra and chemical composition of thirty minerals in magnesite-siderite series. These data indicate that the infrared absorption frequencies shift forward lower wavenumber with increasing the Fe content in these minerals. A linear equation fitted by least-sqare method is as follows Y=880.7-0.1450X where Y is the absorption frequency of v_2 and X is ratio Fe/(Mg Fe)%, the correlation coefficent r=0.9690. This may lead to conclude that there are a close correlation between normal frequencies and chemical composition. |
