Acclivity 20° against to fall the silk brick, in resistance wire Yi Congcao does not drop out. The drum stove pot uses the 1Cr18Ni9Ti stainless steeliness full circle columnar order, or uses the chromium manganese nitrogen high-temperature steel casting, an origin bearing spider outside the furnace bodythe supporting, and uses the electric motor belt speed reducer to carry on the biography to use, to cause the stove pot to revolve slowly, the work piece causes it heating along with drum stove pot revolving to be even, and work piece mutually between non-cover phenomenon, after the heat treatment, theluster is consistent, stove pot another end is a feed head, by two hoop supporting.

滚筒炉罐采用1Cr18Ni9Ti不锈钢制成圆柱型，或采用铬锰氮耐热钢铸件，一端由轴承支座在炉体外支承，并采用电动机带减速机进行传用，使炉罐缓慢旋转，工件随滚筒炉罐旋转使之受热均匀，并且工件互相之间无复盖现象，热处理后色泽一致，炉罐另一端为进料口，由二只滚轮支承。

All the accoutrements are in place, front chromed fasteners, metal rivets and two rear welt lines.

所有的军人配备适当地，前面铬了扣件，桥套铆钉和二个后面的滚边线。

In the presence of acetic acid and polyethylene glycol, chromic anhydride and acenaphthene react under mild condition and acenaphthene can completely convert into acenaphthenone .

在醋酸、聚乙二醇存在下，铬酸酐和苊在温和的条件下反应，苊可以完全转化为苊酮。

Acenaphthenone was prepared by the oxidation of acenaphthene in the presence of chromic anhydride , acetic acid and polyethylene glycol as a phase transfer catalyst under mild reaction conditions with high yields.

The dechroming mechanism of organic acid from chrome shavings was studied from the following aspects,the depolymerization of complex compound,the replacement of H+ and the replacement of organic acid radical anion.

从络合物解聚、氢离子取代和有机酸根阴离子取代3个方面，探讨了有机酸的脱铬机理，认为氢离子的取代和有机酸阴离子的取代起主要作用。

Batch experiments involved the inoculation of acidophilic Thiobacilli and addition of elemental sulfur as their substrate.

序批式试验结果表明，淋滤处理8d，Cr的溶出率可高达100%(污泥中铬的原始浓度为14519mg/kg)。

The oxidation of added sulfur by acidophilic Thiobacilli decreased sludge pH value which caused the solubilization of Cr from tannery sludge.

研究表明，生物淋滤法去除制革污泥中铬主要是通过嗜酸性硫杆菌的新陈代谢使介质酸化而实现的。

Through electron probe\'s analysis to the albite jade, union grinding sample thin slice under polarizing microscope observation as well as X powder crystal diffraction data analysis. Discovery like Chen zhenqiang and "System Gemology" said that secondary mineral for actinolite, green mudstone, epidote and quart.

通过对钠长石玉进行电子探针的分析，结合磨制的样品薄片在偏光显微镜下的观察以及X粉晶衍射数据分析，可知钠长石玉中的主要成分为钠长石，次要矿物为硬玉、角闪石、绿辉石、钠铬辉石；并未发现如陈振强等人以及《系统宝石学》中所说的次要矿物为阳起石、绿泥石、绿帘石、石英。
