This showed that the main peak position of the transmission light is between 530-540 nm, and the color saturation is about 80%. The dense green color of the uvarovite sample is caused by its higher color saturation. The theoretical analysis of the mechanism of the green coloring of uvarovite indicates that the transition of 3d-orbital electron in the Cr(superscript 3+) is responsible for the green color.
采用紫外-可见光分光光度计对样品进行吸收光谱测试,对其颜色指数进行了定量分析,所得样品颜色的主波长为530~540 nm,饱和度为80%左右,进而分析了钙铬榴石的颜色主要由Cr(上标 3+)引起,其呈色机理归因于Cr(上标 3+)的d轨道电子跃迁。

A Novel Method for Intrinsic Viscosity Determination of Polymer SolutionThere are many methods for molecular weight determination of polymers, among which viscometry is used most, it has been broad applied both in production and scientific research. This method is easy to operate with simple instruments and is applicable for broad-range molecular weight, additionally, it has high precision.
在许多情况下,常需要对同种类聚合物的特性粘度进行大量重复测定,如果都按此法操作,每个样品至少要测定3个以上不同浓度溶液的相对粘度,这是非常繁琐的,而且需时较长,尤其在所得样品量极少的情况下,就难以用此法求得高聚物溶液的,为此,人们找到了更快速的近似方法,即"一点法"。
