杂质

Therefore, when Fe2O3 semiconductor doped with acceptor impurities of Ni, the acceptor impurities ionize and lead to the increase of conductive holes in the valence band and hence enhance the conduction capability of Fe2O3 semiconductor.

因此，当Fe2O3半导体中掺入Ni受主杂质后，受主杂质电离，使价带中的导电空穴增多，增强了Fe2O3半导体的导电能力。

我猜是在色谱图中出现了很多不明原因的峰，这些峰不同于其它的杂质峰（根据最后一句话的意思，似乎其它的杂质峰的basemarking width都不同，而这些不明原因的峰的basemarking width值都差不多），所以要在中方人员面前用他们的色谱柱和分析方法再做一遍，但结果还是不理想。

We explained special behavior of CVI2270〓 emission line on the result of particle and impurity transport.

The sample can be admitted to the ion source only after it is completely vaporized, otherwise,the result of masurement will be severly distorted by fractional distillation.

用接近于待测样品中所含的卤代烃的杂质样品与纯净六氟化铀可配置出已知卤代烃含量的"杂质标样"。

Calculation results indicate that the total energy increases when oleic acid is on the surfaces of (001) and (100) of gibbsite respectively. This can explain that the stability of systems decrease when there is some oleic acid on the surface of gibbsite. The calculation results of equilibrium morphology and growth habit show that the volume of growth crystal is larger when some oleic acids with "horizontal" mode exist on the surfaces (001) and (100) of gibbsite.

计算结果表明：油酸接近氢氧化铝(001)和(100)表面时，体系总能量升高，说明油酸的存在可降低体系的稳定性；油酸在氢氧化铝(001)和(100)表面上时，油酸分子呈"卧"式时，长大后晶粒体积大于无杂质存在的情况，而油酸分子呈"立"式时，长大后体积小于无杂质时晶粒的体积。

Unfinished fabrics, referred to as greige or grey goods, contain many impurities , have a harsh hand and little esthetic appeal.

未经整理的织物一般称为坯布，坯布多含有杂质，手感粗糙，外观不佳。杂质常常在晶粒间界偏析。

The deformation mechanism is mainly the single-slip and cross-ship, the fracture mechanism is mainly the congregation of transgranular micro-hole, and large uniform deformation occurred before tough fracture, and therefore, the ability of plastic deformation and the mechanical properties of the material were remarkably improved. These fully indicate that the new melt-treatment developed in this work is an effective and advanced technique, and further testify that the improvement of metallurgical quality of the material is the key to enhance its mechanical properties, especially its plastic deformation performance. The results of tensile and compression tests at elevated temperature also indicate that the suitable hot-working temperature range is 400～450℃. 4. A steady-state plastic flow exists during the plastic deformation of the aluminum sheet used for pressure can at elevated temperature. A hyperbolic sine relationship can be satisfied between the steady-state flow stress and strain rate by introducing an Arrhenius term which involves some thermal activation parameters, i.

压力罐用铝材中的主要冶金缺陷为Al〓O〓夹杂物、气孔及富Fe杂质相；高效熔体处理显著改善了材料的冶金缺陷的存在形态，使含杂量明显减少、夹杂物尺寸变细小且分布均匀，富Fe杂质相变为细小、分布均匀的团球状或短棒状的复杂化合物，同时也明显细化了结晶组织；此外，由于高效熔体处理有效地减少了材料中裂纹萌生源数量，因而改变了材料的塑性变形微观过程及断裂方式，主要以单滑移和交滑移进行塑性变形，断裂方式为穿晶微孔聚集型，韧性断裂前产生了大量的均匀变形，不易出现变形失稳，从而显著提高了罐用铝材的塑变能力和力学性能。
