The energy spectra of hot electrons have been measured using the magnetic spectrometers, fitted with the LiF thermoluminescent dosimeter which were calibrated using Cs~(137)γ-ray sources, in the interaction of a 130 mJ, 60 fs, 800 nm, 1∶10~(-6), 7.0×10~(17) W·cm~(-2) P-polarized laser incidence on Cu foil target at an angle of 45° with respect to the target normal without any prepulse.

在激光能量130mJ，脉宽60fs，波长800nm，对比度1∶10-6，激光与靶法线成45°夹角， P偏振，靶面激光峰值功率密度约为7.0×1017W·cm-2，无预脉冲的条件下，采用电子谱仪与经γ标准源标定的LiF热释光探测器相配合，测量了飞秒激光薄膜靶相互作用中产生的超热电子能谱。

So that it can be considered as that all materials can all be composed and transformed unitedly time after time by electrons and positrons.

因而，可以认为：一切物质都是统一由&电子&与&正电子&逐次组合、转变而成。

In regions where the electrons are unmagnetized, the grad-B drift is set equal to zero.

在地区电子磁化，奇格勒乙漂流定等于零。

In this thesis, an unmagnetized, collisionless dusty plasma which consisted of extremely massive, highly negatively charged dust particles, ions and electrons are studied. Considering the effects of hot dust fluid with non-thermal ions and variable dust charge, we study the self-consisted system parameters on the structures of the dust-acoustic solitary waves by reductive perturbation methods.

本论文研究无磁化、无碰撞的、由大质量且带负电量的尘埃颗粒、电子和离子组成的尘埃等离子体，考虑尘埃流体的温度、非热离子和尘埃颗粒电荷绝热变化的因素，使用约化摄动方法研究这个自洽的系统的参数对尘埃声孤波结构的影响。

The third, since the electrons in the plasma are accelerated and ions move together, some harmful effects are also observed, such as both output powers of RBWO and FEL decrease versus the increase of plasma density. The results agree with the results of linear fluid model. In the unmagnetized plasma-loaded RBWO-FEL, output powers of pump source and FEL are obtained only in a narrow plasma density range and both have maximum. The results of simulation are in good agreement with the experimental results.

模拟分析了磁化等离子体填充的RBWO-FEL，尽管没有发现等离子体填充后RBWO及FEL输出功率的成倍增长，但是观察到等离子体的引入对RBWO-FEL产生以下影响：泵波及FEL的辐射频率的线宽得到明显增加；在较高的等离子体密度下，TM〓模将会被完全抑制；首次观察到T-G模振荡及功率输出，结果同线性理论计算结果基本一致；等离子体中的电子被加速及背景离子的移动将对器件工作产生不利影响。

The three people who keep the office going, Winy, Jacob and Nathalie, move about like electrons, giving instructions on one side and another Everything has to be set in motion before start the discussion!

三个人看守着主个办公室的情况，WINY， JACOB，NATHALIE，他们的移动就象电子，给这边和那边指导。（在讨论之前所有东西都要被设定）这段引子把读者带到建筑师生活的城市并且描述了他们的事务所中工作场所的氛围。

It is formed from the ionisation of atoms of air (i.e. electrons from removed from the atom) by incoming solar radiation.

它被形成从空气(即电子原子的电离从从原子去除)由接踵而来的太阳辐射。

In the presence of a high voltage discharge in an air gap, free electrons, which are always present in the air, accelerate and ionise the gas.

在场的高电压放电的空气间隙，自由电子，这是始终存在于空气，加速和ionise的天然气。
