Three dye lasers are used to excited Ba atoms to obtain ions and electrons through autoionization process.

本文采用三台染料激光器分步激发Ba原子，利用自电离过程产生离子或电子。

The differences between the above autoionizing Rydberg states were analyzed and proven to be significant. Much attention has been paid on the autoionization spectra and properties of ejected electrons from autoionizing states for both Ba and Mg atoms,especially their characteristics and laws.

分析和研究了不同自电离Rydberg系列之间的明显差异，特别关注了Ba和Mg原子在自电离光谱和自电离弹射电子的能量分布这两方面的特性和规律。

The Ba atom is a typical two-electron atom, whose autoionization spectra and angular distributions of ejected electrons from autoionizng states are significant for understanding the complex structures and physical mechanism of the alkaline-earth atoms.

Ba原子作为一种典型的双电子原子，其自电离态的光谱和弹射电子角分布的特性研究，对人们认识原子的复杂结构和内部动力学过程具有重要的科学意义。

Meanwhile Pierre Colin of the Max Planck Institute for Physics in Munich and his colleagues reckon that the shadow of the moon could be used to help work out whether the abundance of positrons actually does come from annihilating dark matter, using telescopes that look for Cherenkov radiation —flashes of light in the sky—that are created when cosmic rays, in the form of high-energy electrons and positrons, hit the upper atmosphere.

同时，在慕尼黑的马普物理研究所的皮埃尔·科林和他的同事们指出：可以用望远镜观测月球阴影下的切伦科夫辐射现象来判断大量的正电子是否的确来自湮灭的暗物质。切伦科夫辐射现象，是指带有高能量的电子和正电子的宇宙射线，撞击外层大气层时在天空中产生的闪光现象。

The measurements made by Van Allen's experiment led to an unexpected and startling discovery -- an earth-encircling belt of high energy electrons and ions trapped in the magnetosphere now known as the Van Allen Radiation Belt.

Van Allen的实验测得的结果找到了意想不到、令人吃惊的发现—在地球磁气圈外截流了一条环绕地球的高能电子和离子环，现在被称为 Van Allen辐射带。

"Compton effect: Change in wavelength of X rays and other energetic forms of electromagnetic radiation when they collide with electrons. It is a principal way in which radiant energy is absorbed by matter,"

康普顿效应：电子对X射线和其它高能电磁辐射的弹性散射引起波长增大的现象；这是物质吸收辐射能的一种主要方式。

The cathode-ray tube or "Crookes' tube" like object depicted in scenes from the temple of Hathor at Dendera may depict a relativistic source of these heavy electrons - which could drastically expedite the magical processes which involve these particular tubes.

阴极射线管或&克鲁克斯管&就像来自Dendera哈索尔神庙场景里描述的物体可能描述这些重电子一个相对论的来源点-重电子可以激烈加速这奇异的局限在这特别管里的作用过程。

To getrid of these shortcomings DMs are presented in quantum theorywhere the movement of individual electron is determined byquantum mechanics and the system of electrons obeys Fermi-Dirac statistics,in consequence they can find wider appli-cations than classical DMs.

这里个别电子的运动由量子力学刻画，多电子系遵循Fermi-Dirac统计规律，故它们比前三种经典公式普适性更强。

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