查询词典 Valence

There are blue and green emission spectral series in the phosphors activated by three valence ions of Terbium.

三价铽离子激活的磷光体有兰色和绿色两个发射谱线系列。本文分析了这两个系列谱线的强度，随着激活剂浓度而变化的实验结果，发现在激活剂浓度达到一定数量之后，当继续增加激活剂含量时，兰色和绿色发射谱线相对强度的变化规律，和加入敏化剂的结果是一致的。

The valence of titanium in the lithium titanate is +4, which was proved by X-ray photoelectron spectroscopy.

对产物进行X-射线光电子能谱研究，结果表明：水热法合成的钛酸锂中钛为＋4价。

An element bonding parameter topological index HLA is proposed based on topological principle and valence shell electron structural character.

基于元素键参数拓扑指数原理以及镧系元素价层电子结构特征构建了一种新的拓扑指数HLA。

The results show that defect states appearing both in the valence and conduction band induce the corresponding electrons scattering because of the deformation of Stone-Wales defects (two pentagon-heptagon pair topological defects).

结果表明，由两个五元环—七元环(5-7)拓扑缺陷对构成的Stone—Wales形变使价带和导带中出现缺陷态，导致相应能级的电子散射。

Doped high consistence Co can't increase the density of defect levels. ZnO doped Fe is different from doped Mn or Co totaly, the density of photoelectrons anddefect levels aren't reduced obviously. It's probably related the valence of Fe in crystal,general think trivalence of Fe, and form donor levels in ZnO.

Fe掺杂的ZnO完全不同于Mn、Co掺杂，其光生电子密度没有因掺杂出现明显的降低，即缺陷能级密度没有降低，这可能和掺入ZnO所呈现的价态有关，一般认为Fe为三价态，在ZnO中形成施主能级。

The upshift of valence band edge and the downshift of conduction band edge under tensile strain are responsible for that.

这是因为外加伸展应力使得矽的价电带往上移动以及导电带向下移动造成。

The upshift of valence band edge under mechanical strain increases the majority hole concentration at the oxide/Si interface.

价电带的向上移动会使得氧化层以及矽的接面的电洞浓度增加。

Of or relating to uranium, especially with valence lower than in comparable uranic compounds.

铀的铀的或与铀有关的，尤指比同类铀化合物化合价低的

Of or relating to uranium,especially with valence lower than in comparable uranic compounds.

合铀的铀的或与铀有关的，尤指比同类铀化合物化合价低的

The valence electron structure of WC and C has been calculated.

取得了满意的结果。

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

"This skylark is a present from my master," he says.

"这只云雀是我主人献上的礼物。"他说。
