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。

The results of toxicity experiments showed that R32 would not cause acute, chronic, cumulative and genetical toxicity effect on algae, Allium cepa, Zebra, fish and mice before it absorbed Cr. The recovery and sterilization measurement in routine water treatment could reduce most of the R32 in effluent. This may ensure that the effluent would not cause any ill effect on all kinds of biology in the environment after it was discharged into the river.

毒性实验结果表明：在吸附Cr~(6+)以前R_(32)对微生物无致突变性，对藻类、洋葱、斑马鱼和小鼠无急性毒性、慢性毒性和蓄积毒性；吸附Cr~(6+)后，常规水处理中的各种回收和杀菌措施可以降低出水中R_(32)的量，使出水排入江河后不会对环境中的各种生物产生不良的影响。

The impact of dissolvable Cr in fly ash on soil and groundwater was evaluated based on the above tests.

研究了外界水渗透通过粉煤灰硬化体时，其中可溶性Cr在硬化体、土壤、渗滤液中的迁移转换规律，评估了粉煤灰硬化体中Cr的溶出及其对土壤和地下水可能产生的影响。

Methods: Co-Cr alloy,Ni-Co alloy and casting titanium were respectively proc essed into size of 10 mm×10 mm×1 mm in tablets.

发现多孔炭对酚类化合物及Cr的吸附以化学吸附为主，其中对酚类化合物的吸附由羧基与内酯基的表面密度合量决定，对Cr的吸附由表面官能团中羧基和内脂基含量的合量决定；多孔炭对I2的吸附以物理吸附为主，由孔容决定。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
