通过显微镜下观察、电子探针、X射线粉晶衍射等常规岩石测试方法，并结合阴极发光，得出天蓝玉与翠绿玉的绿色部分主要为含铬的云母；绿粉玉中的绿色部分颜色产生与绿帘石有关，且由于Fe的含量比较高，造成了绿色部分比较暗淡，不鲜艳，且颜色较浅；绿白玉中绿色部分，经矿物分析主要为透辉石，且Cr、Fe含量都比较高，暗绿颜色成因与透辉石有关。

We use in 316 steel pipes chromium content should after 16%-18% the steel joins elements and so on chromium, can change the steel the performance, like the example steel's molecular structure is evener, produces compact oxide compound protective film in the steel superficial change and so on, thus sharpens the stainless steel anti-corrosive ability greatly.

The practice is introduced for producing extra-low carbon ferrochromium with Perrin process of adding some silico-chromium to reduce FeO in molten chrome ore-lime to increase the ratio of Cr/Fe , and producing high chromium products (Cr≥72%) with this melt.

介绍了波伦法冶炼微碳铬铁过程中，先加入部分硅铬还原铬矿-石灰熔体中的Feo，以提高Cr/Fe；然后用此熔体生产出含Cr≥72％的高铬产品的生产实践。

Cyclic voltammetry indicated that there were Cr→Cr, Cr →Cr oxidation reaction on anode, while there were Cr→Cr, Cr→Cr, Cr →Cr deoxidization reaction on cathode. The graphite electrodes treated by acid and heating could enhance the reversibility and kinetic of the electrode reaction. The nature graphite electrodes had been eroded during charge/discharge process, while the graphite electrodes by activation could avoide corroding by hexad chromium ion. The reversibility and kinetic of the electrode reaction of chromium ion on activation electrode had been increased, so which indicated that graphite surface augment oxygenous function corps which could increase electrode hydrophile capability.

循环伏安实验表明：铬液流电池的电极反应非常复杂，在阳极存在Cr→Cr，Cr→Cr的氧化反应，在阴极存在Cr→Cr，Cr→Cr，Cr→Cr的还原反应；热处理的石墨电极和重铬酸钾处理的石墨电极能提高电极反应的活性和可逆性；在充放电实验中未处理的石墨电极发生严重腐蚀；分别用这两种方法处理过的石墨电极具有防止六价铬侵蚀的功能；铬离子在活化处理过的石墨电极上的反应活性和可逆性增加，可以认为：重铬酸钾溶液活化处理和加热处理后的石墨表面的含氧官能团增加，电极亲水性增强。
