The entanglements of the methylene groups adjacent to the CO and NH groups, are less pronounced owning to the formation of interchain hydrogen bonds.

与CO和NH基团相连的亚甲基基团的缠绵结不很明显，主要是因为尼龙6链间氢键的存在。

The effect of 1% V2O3 additive on iron carbide formation by two steps was studied in H2-CO-CO2 mixtures at

在853~973 K以及H2-CO-CO2气氛中，研究了添加质量分数为1%的V2O3对二步法制备碳化铁的影响。

The experimental results show that high conversion ratio of iron carbide could be obtained using reducing gas with suitable ratio of H〓/CO at 973K and 1073K.

试验结果表明在973K、1073K下反应时，选择合适H〓／CO比例的反应气体能得到较高碳化铁转化率，而1173K下未能得到。

In addition, the HC and CO emissions are much lower than the emissions of HCCI and the indicated thermal efficiency of HCCI/DI is higher than the prototype diesel engine.Furthermore, without spark ignition and hot EGR, the HCCI/DI combustion of in-cylinder directly injected iso-octane is achieved with the induction of thermal and chemical active atmosphere generated by the HCCI combustion of port injected n-heptane.

通过对燃料理化特性、预混合率和缸内直喷时刻这三个影响因素的优化，实现了对HCCI/DI燃烧相位、放热分布和形态的调制，使发动机的负荷拓展到全负荷，在全负荷范围内NOx排放低于40×10-6排放水平，HC和CO排放显著低于HCCI燃烧，同时发动机指示热效率η_i高于原机柴油直喷的水平。

The ambient-temperature tensile strength of the joint brazed with Cu-Co-Ti filler metal is slightly higher than that brazed with Cu- Ti filler

两种接头的的室温拉伸强度均较低，但Cu-Co-Ti钎料接头的强度高于Cu-Ti钎料接头。

Compared with the joint brazed with Cu-Ti filler metal, the content of Cu in the reaction layer adjacent to the stainless steel is higher than the joint brazed with Cu-Co-Ti filler metal, so is the content of Nb in brazing seam.

与Cu-Ti钎料接头相比，Cu-Co-Ti钎料接头中钎缝与不锈钢侧的反应层中Cu含量较高，钎缝中Nb含量也较高。

A combustion chamber study was conducted for four types of joss papers and five types of incenses. Solid and gas phase pollutants from each burned joss paper and incense were quantitatively collected with a micro-orifice uniform deposited impactor and gaseous pollutant (NOx, SO2, and CO) analyzers, respectively. VOC were detected by a GC-MS.

本研究选取市面上常用之2种金纸及5种拜香，加上2种改良金纸，将其分别置於金炉或燃烧室内，自然或强制通入空气进行燃烧，配合微孔均匀沈积冲击器及气态污染物(NOx、SO2、CO及VOCs)分析仪，於模拟一般在金炉及室内燃烧金纸及拜香情况下，依不同粒径分布收集金纸及拜香燃烟中之粒状及气态污染物，并分析飞灰中金属成份之分布。
