The effed Of three-dimensional perturbed velocities and three-dimensional perturbed current densities on the beam-wave interaction of plasma-filled dielectric Cherenkov maser is analysed by use of the self-consistent linear field theory without considering the effect Of the longitudinal guided magnetic field.The dispersion relation and the Simultaneous condition of the beam-wave interaction are derived. It is clearly shown that the instability of the interaction results from the coupling of the TM mode in t...

Regarding to Chinese information productions export policy, the government should put important point on the export competitiveness, enhance to introduce foreign capitals, increase innovation ability in Chinese enterprises. Moreover, security system should be built to respond to non-tariff barrier oversea, the external competition environment should be improved. At the same time, we should enhance information productions export motivation system, and make an effort to explore various international markets.

The conclusion is drawn from the simulations that the secondary electrons will go out from the sample surface more easily with the decrease of the half cone angle of tip and the increase of secondary electron energy, tip-sample separation and the distance of the emission site away from the point directly under the tip.

模拟的结果发现针尖半锥角越小、次级电子能量越高、针尖样品间距越大、次级电子出射位置离针尖正下方越远则越有利于次级电子的逸出，此外通过栅网与一个平行于样品表面的地电极的共同作用，会对次级电子产生聚焦作用。

At ψ=30°. 2. To obtain 〓 from the background of a direct Auger spectrum N Because the total Auger electron yields are only about 10〓 of the backscattered electron yields in the N spectra, the backgrounds of the N spectra are mainly formed by the backscattered electrons.

由于N谱中俄歇电子的产额只占背散射电子产额的10〓左右，因此背景主要由来自样品的背散射电子构成，其中包含着与背散射电子能量分布有关的信息。

Based on Stuart et al.'s electron density evolution equation, the electron density evolution process in fused silica film irradiated by short-pulse laser for τ∈[0.015] ps were studied by means of numerical method. The effects of initial electron density N and laser pulse width τ on laser threshold intensity I and damage threshold fluence. F were analyzed respectively.

The electron location function shows the electronic density changes at both the atomic vacancies and antisites. There is an obvious absence of electronic areas where the vacancy of Ga has the dangling bonds of N, which are favourable for the sdsorption of metal atoms. In contrast, at the vacancy of N, there is more electron distribution(ELF:0.16-0.45), forming lone electron pairs which are profitably available to combine electronegative atoms.

电子局域函数显示了表面空位和替位处的电子密度变化，表面Ga原子空缺处有非常明显的缺电子区域，悬挂键临近N的电子密度增大，有利于对金属原子的吸附；N原子空位处的ELF值为0.16-0.45，有利于同电负性较大的原子结合。

Based on the structure, those human diseases related mutation sites are mapped onto the structure accurately. As a result, it is found that these sites are all around the electron transfer prosthetic groups or ubiquinone. And these mutations will alter prosthetic groups' binding or ubiquinone's binding, causing electron leakage from the prosthetic groups in the electron transfer chain, producing reactive oxygen species and leading to tumor formation.

利用线粒体复合物 II 的结构对已知与人类疾病相关的该复合物突变位点进行了精确定位，发现这些突变位点均位于电子传递体或辅酶 Q 结合位点的周围，它们的突变或影响了电子传递体的结合，或影响了辅酶 Q 的结合，从而导致电子传递的中断，电子逃逸到线粒体基质中或线粒体内膜中，经过一系列下游途径导致疾病的产生。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。
