Ca(上标 2+)、Ba(上标 2+)对提高酶活力具有明显作用。

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。
