The numerical results show that lossy dielectric-load can heighten the start oscillation current of absolute instability, and increase depends on the magnetic field strength and the perpendicular-to-parallel velocity ratio of the electrons; The thickness of the lossy waveguide increases the start oscillation length of backward wave oscillation.

结果表明：损耗介质的加载，可以提高绝对不稳定性起振电流，提高的幅度依赖于工作磁场偏离饱和磁场的程度、电子束横纵速度比等；增加波导损耗介质加载的厚度，可以提高竞争模式的回旋返波起振长度。

At absolute zero, a pure semiconductor has all of its electrons tightly bound and acts as insulator.

在绝对零度时，纯半导体所有的电子都紧紧结合在一起，因而显示出绝缘体的性质。

At absolute zero, a pure semiconductor has all of its electrons tightly bound and acts as an insulator.

在绝对零度时，纯半导体所有电子都紧紧结合在一起，因而显示出绝缘体的性质。

This noise is the voltage associated with the motion of electrons due to their thermal energy at temperatures above absolute zero.

这种噪声是与在高于绝对零度的温度下由热能所引起的电子运动相关联的。

Models of element synthesis during the supernova explosions predict that the abundance ratios of actinides with respect to other stable elements heavier than iron are very sensitive to the environment of the explosion, such as the entropy and the ratios of protons, neutrons and electrons.

模型元素的合成，在超新星爆炸预言的丰度比锕对于其他稳定更重的元素，比铁很敏感，对环境造成的爆炸，如熵和比例的质子，中子和电子。

The process of oxidizing; the addition of oxygen to a compound with a loss of electrons; always occurs accompanied by reduction.

氧化过程；化合物失去电子获得氧的过程；总伴随着还原作用而发生。

The result shows that the magnetic field effectively confines the electrons. Electrons are collected in a small region. Due to the special electromagnetic field, the ion beam has a two-peaked distribution.

结果发现圆柱形阳极层等离子体加速器的磁场对电子有明显的约束作用，电子集中于阳极附近很小的区域内。

Therefore, more electrons close to the core, the interaction between the electrons and the core more, and the self-energy more.

所以与核靠近的壳层上的电子越多，电子与核内静电吸引的排斥力就越大，产生的自能修正就越大。

We point out that the effect of action between semicore electrons and valence electrons can be neglected in self-energy correct.

指出在Si，Ge这种原子序数较小的sp系统中，半芯电子与价电子相互作用对自能修正影响可以忽略不计。

The electronic structures of cluster Fe8 with D6h symmetry and Fe15 with Oh sysmmetry have been studied by MS-X method..The results show that(1 the exchange splittings of the d-band and the magnetic moments of the Fe-atoms are different in the two clusters;(2)the change distribution in both clusters is not uniform,showing that the electrons are transferred from peripheral atoms to inner atoms,and the spin-directionof the electrons transferred is in accordance with the symmetric characteristics...

用MS-Xα方法研究了Fe8原子簇（具有D6h对称）和Fe15原子簇的电子结构，结果表明：（1）两种原子簇中的Fe原子磁矩及其d能带中的交换劈裂性质互不相同；（2）两类原子簇中的电荷分布不是均匀的，电荷倾向于从外围原子向内部原子上转移，并且被转移电子的自旋方向与原子簇的对称性质密切相关。
