And the electroreduction process of nitrobenzene on WC powder electrode in basic solution is investigated by cyclic voltammetry, linear potential sweep and chronoamperometry. In the process of electroreduction of nitrobenzene on WC powder electrode, liquid phase mass transferring may be the control step.

并且也用循环伏安、线性扫描和恒电位阶跃等测试方法研究了碳化钨粉末电极在碱性介质中析氢和还原硝基苯的电化学特性，发现碳化钨在电催化还原硝基苯过程中，可能主要受反应物的液相传质控制。

Therefore, this process is firstly used to form the chromium carbide layer on the surface of the axle sleeve and bush in the immersed roller used for Strip-Hotgalvanizing unit to improve their working life.

熔渣法碳化铬被覆处理可以在钢铁表面形成牢固、致密的碳化铬覆层，已广泛应用于提高工模具和机械零件的耐磨性能。

It was shown by further research that the formed tungsten oxide had an obvious layer-like structure, where from outer to inner layer the valence of tungsten increased and the reduction degree decreased. The carbonization of W depended on the replacement of W atom at the center of the body-centered cubic by C atom and the minor adjustment of C atom position and the lattice parameters.

深入研究表明，氧化钨碳还原颗粒具有明显的层状结构，自外到内钨的化合价递增，还原程度降低；钨的碳化是碳原子替换体心立方钨晶胞的中心钨原子，然后碳原子转换到钨原子点阵间隙再经晶胞常数微调而形成。

The crystallinity of wet-spinning PAN precursor fibers gradually reduces during preoxidation process, while it gradually increases during carbonization process.

湿纺PAN原丝的结晶度在预氧化过程中逐渐降低，在碳化过程中随着碳化温度的升高逐渐增加。

Travel time in WC anvils was measured using pulse reflect method at room temperature and under cell pressure up to 3.0GPa.Experimental results indicate that the travel time in the WC anvils decreased linearly with cell pressure.

在常温、实验压力为0～3GPa条件下，利用脉冲反射法测量了纵波在碳化钨压钻中的走时，结果发现，随实验压力升高，碳化钨压砧的走时线性减少。

The database consists of 1 : 1 000 000 digital soil map, soil profile attribution database, and soil reference system.

基于中国1：100万土壤数据库，利用土壤有机碳储量和碳密度的空间化表达和计算方法研究中国土壤有机碳密度及储量。

Since 2002, the company has developed various types of more than 20 kind of the dry and wet type of sandblast machine altogether (aluminium quality, copper, iron, gather urethane sandblast machine), more than 100 kind of nuzzle (including in wolfram steel, carbonization boron, carborundum, compound pottery and steel nuzzle), and other many kinds of sandblasting machine fittings, the great one has met lots of sandblast machine factory and sandblast sales departments to many kinds of demands for sandblast machine.

从2002年开始，公司共开发了二十几种各式干湿型喷砂枪（铝质，铜质，铁质，不锈钢，聚氨酯喷砂枪），一百多种各规格喷咀（钨钢，碳化硼，碳化矽，复合陶瓷及钢质喷咀）以及其他多种喷砂机配件，极大的满足了各喷砂机械厂及喷砂销售部对多种喷砂配件的需求。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
