The current studies on the catalysts for n-heptane isomerization were reviewed systematically. The factors influencing the catalyst properties were discussed. The noble matel catalysts supported on SAPO HZSM-5 and Y .β zeolite were widely studied for n-heptane isomerization.

阐述了当前正庚烷异构化所用的负载型催化剂和过渡金属碳化物和氧化物催化剂的研究进展，对催化剂性能的影响因素及对策进行了分析与讨论。

In the interfacial layer near to SiC, elements Pd and Ni preferentially diffused to SiC and resulted in the reaction products of Pd-Si phase, Ni-Si phase and graphite. In the reaction zone further away from the SiC, mainly elements Cr and V in the brazing filler participated in the interface reaction, and formed Cr-C, Cr-Si, Cr5Si3C. In the central part of the joint, the matrix was composed of Pd-Si, Ni-Si and V-Si phases, on which some blocky carbides V2C, Cr23C6 distributed scatteringly.

MPa。微观分析表明，在靠近SiC的界面反应层中，主要是Pd和Ni优先与SiC反应生成相应的Pd-Si相，Ni-Si相和石墨；接头中在离SiC稍远的区域，主要是Cr和V与母材扩散进入钎缝且未与Pd和Ni反应的C和Si发生反应，生成Cr-C， Cr-Si， Cr5Si3C 等相；钎缝中心区的基体由Pd-Si，Ni-Si和V-Si相组成，其上弥散分布着块状碳化物V2C和Cr23C6。

" Carbide: Inorganic compound, any of a class of chemical compounds in which carbon is combined with a metal or semimetallic element."

碳化物：碳与金属或半金属元素化合而成的一类化合物的总称。

The results show that the coverage area of tungsten film on diamond surface is above 90% and the steady tungstenic carbides WC and W2C are created by this technology. The tungsten film coated on diamond is realized.

结果表明，该方法可在金刚石表面镀覆上一层覆盖面达到90%以上的金属钨膜，且生成稳定的碳化物WC和W2C，得到由难熔金属钨包覆的金刚石。

The matrix of the work layer of such kind of roll contains evenly-distributed graphite in the state of pellets, balls, vermes or sheets besides carb ides and ledeburite. Therefore, this material has not only better resistance to wear, but also better properties of resistance to spalling and fire crack.

由于该类轧辊工作层基体组织内除含有碳化物和莱氏体外，还存在均匀分布的球状、团状、蠕虫状或片状石墨，正因如此，除自身具有较好的耐磨性外，还具有较好的抗剥落性、抗热裂性。

Based on the critical transformation temperature, high speed steel was annealed, quenched and tempered in order.

着重研究了热处理过程中碳化物演变对轧辊用高速钢性能的影响。

With increasing aging temperature, the precipitates coarsened and tended to segregate at grain boundaries, causing the decreased strength and the degraded SME.

同时添加RE和碳的Fe-25Mn-6Si-5Cr-0.29RE-0.11C合金在不同温度下时效后，获得了含稀土的碳化物沉淀相。
