着眼点目标
5) cat's eye
猫眼石,猫睛石,猫儿眼
6) nephrite cat's eye
软玉猫眼
1.
The results indicate that the main phase of the nephrite cat's eye is tremolite,and the main impurity ions are Fe~(3+), Fe~(2+) and Mn~(2+).
采用电子探针、Raman光谱和电子顺磁共振吸收谱对新近发现的四川软玉猫眼进行了研究。
2.
The results indicate that the main composition of nephrite cat's eye is tremolite.
用差热分析(DTA)、Fourier变换红外吸收光谱(FTIR)和X射线粉晶衍射(XRD)测试方法对四川软玉猫眼的热相变产物和相变机制进行了研究。
3.
Electronic microprobe analysis (EMPA), X-ray diffraction (XRD), Raman spectrum, scan electronic microscope (SEM) and polarized optical microscope were used to study nephrite cat's eyes from Sichuan Province,Southwest China .
结果表明 ,四川软玉猫眼主要由微晶隐晶质透闪石矿物集合体组成 ;透闪石主要呈近于平行定向排列的显微纤维状 ,显微纤维变晶结构是软玉猫眼的主要结构 ,具有此结构的软玉能表现出良好的猫眼效应 ;透闪石纤维较粗、相互聚集形成束状或捆状结构时 ,猫眼的眼线比较分散 ,猫眼效应较差 ;透闪石纤维局部相互穿插绞合是软玉猫眼表现出高韧性和较强抗断裂性能的主要因素。
