中文摘要：

采用拉曼光谱、傅里叶变换红外光谱、电子探针波谱以及X射线粉晶衍射谱对四川软玉猫眼进行谱学研究。结果表明软玉猫眼主要由透闪石组成。计算所得的平均化学式为：（Ca1.96Na0.02）（Mg4.52Fe0.59Mn0.03）5.14[（Si7.92Al0.04）7.96O23]。其红外吸收频率主要出现在940 cm^-1-1105 cm^-1、650 cm^-1-760 cm^-1和450 cm^-1-510 cm^-1范围内。3600cm^-1-3800 cm^-1范围内OH基伸缩振动拉曼谱带分裂，并向低波数方向位移，主要与Mg^2＋和Fe^2＋的含量有关。

英文摘要：

Raman spectra, Fourier transform infrared （FTIR） absorption spectra, electron probe micro section analysis（EPMA） and XRD were used to study nephrite cat＇ s eye from Sichuan province. The results have indicated that the nephrite cat＇ s eye consists of tremolite, whose chemical composition being （ Ca1.96 Na0.02 ） （ Mg4.52 Fe0.59 Mn0. 03 ） 5. 14 [ （ Si7. 92 Al0.04 ） 7. 96 O23 ]. The major absorption frequencies of the nephrite cat＇ s eye have appear around 940cm^-1 - 1105cm^-1, 650cm^-1 - 760cm^-1和 450cm^-1 - 510cm^-1. The division of OH stretch vibration band around 3600cm^-1 -3800cm^-1 shifting to the lower wave -number mainly has connected to the content of Mg^2＋ and Fe^2＋ .
