查询词典 Valence

The results indicate that the relative atom content of Nd islow contrasted to that of Fe, which results from the weak competitive reaction ofNdCl〓 because of the strong bulk effects. The results of x ray photoelectronspectroscopy reveal that other valence of Fe could be in NdCl〓-FeCl〓-GIC.It is considered as the result of the charge shift between FeCl〓,〓 and graphitein intercalating process. Structural model of RECGIC was supplemented after thinking of the chargeshift between the intercalates and graphite. The characteristic layer distance, I〓, ofstage-1 RECGIC were calculated by the model.

利用能谱分析测定了NdCl〓-FeCl〓-GIC中插入剂的含量，结果表明， Nd的相对含量低于Fe的相对含量，这是因为NdCl〓的空间效应较大，而致使其竞争插入反应处于劣势的缘故。X光电子能谱研究表明，Fe可能有其它价态存在，这是由于在插入反应过程中，FeCl〓、NdCl〓以及石墨间发生电荷转移等作用的结果。

从吸收特性表明，Co离子掺杂于畸变的氧八面体中，呈现+2价态，并且沿着晶体生长方向浓度逐渐减少，Co2+在LiNbO3晶体中的有效分凝系数大于1。

Valence bond theory is paralleling with the MO theory in the history.

价键理论在历史上是与分子轨道理论平行发展起来的。

The XPS results show that the amount of low valence molybdenum and S(superscript 2-) increases with increase of the content of K in sulfured catalyst, and(superscript 2-) is suppressed. It is found that keeping the ratio Mo(superscript 4++Mo(superscript 5+)/Mo(superscript 6+) at 0.8~1 level and remaining more S(superscript 2-) species on the catalyst are in favor of the improvement of the catalytic activity at low temperature.

XPS表征显示，硫化态催化剂随着钾添加量的增加，低价态钼和S(上标 2-)增加，(上标 2-)受抑制，Mo(上标 4++Mo(上标 5+)/Mo(上标 6+)质量比为0.8~1和较多的S(上标 2-)物种有利于提高催化剂的低温活性。

The research of the digital audio-frequency technique combining the embedded system has the extensive foreground, The digital audio-frequency equipments based on the embedded system have be attended all over the world because of its high ratio of sexual valence , the quickly development speed ,and etc.

结合嵌入式系统的数字音频技术研究有着广阔的前景，基于嵌入式的数字音频设备以其高性价比、日新月异的发展速度等优点受到世界各国的广泛关注，本文结合市场发展需要，提出了一个比较优化的解决方案，并从理论和实践两方面对该方案进行了分析和设计。

The outer valence shell binding energy spectrum of benzyl alcohol was also obtained.

实验在非共面对称几何条件下完成，入射电子的能量为2400 eV加结合能。

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。

It can be proposed that the charge compensation effects make Co2+ and Ti4+ ions in raw material co-occupy uniformly B site in perovskite both as the forms of +3 valence, which is responsible for the lower temperature synthesis.

这是由于原料中的Co2+和Ti4+离子通过电荷补偿作用使产物B位的两种金属均以+3价氧化态分布所致。

It can be proposed that the chargecompensation effect between Co~(2+) and Ti~(4+) ions in raw materials make them tendto co-occupy uniformly B site in perovskite both as the forms of +3 valence, which isresponsible for the lower temperature synthesis.

分析认为，原料中的Co~(2+)和Ti~(4+)离子通过电荷补偿作用(charge compensation effect，CCE)使二者均易于形成Co~(3+)和Ti~(3+)离子去共同占据ABO_3型钙钛矿结构的B位，这种电荷补偿作用导致样品具有较低的合成温度。

Cable dampener cannot be rolled up but must be hung over the cable.

缆帆不能被卷起，必须保证处于展开状态
