In this paper,the diffraction and the interference of electrons from a double slit and a multi-slit have been analyzed by quantum theory, and the results are in keeping with light s.

运用量子理论分析了电子双缝、多缝的衍射、干涉，与光的双缝、多缝的衍射、干涉完全一致。

Double slit diffraction is the double slit interference phenomenon modulated by single slit diffraction.

双缝衍射是指被单缝衍射调制的双缝干涉现象。

Thomas Young s career is recounted, Young s experimental research on the interference of light(especially which related except for the double\|hole or double\|slit experiment)and his principle of interference of light are reviewed.

介绍了托马斯·杨的生平，回顾了杨在光的干涉方面所做的有关实验研究，特别是双孔双缝之外的其它干涉实验，讨论了杨对干涉原理的论述和解释，以及对我们的有益启

Non-sequential double ionization rate and the double ionization events that sum of two-electron momentum equals zero decrease.

时，非时序双电离率和两电子动量和为零的双电离事件数却减小。

The results show that non-sequential double ionization rate and the double ionization events that sum of two-electron momentum equals zero increase with the molecular internuclear distance increasing when the molecular internuclear distance is within 1.0a.u.

结果表明，分子核间距在1.0a.u。-6.0a.u。范围内时，非时序双电离率和两电子动量和为零的双电离事件数随着分子核间距的增大而增大。
