| 8. | For example , one of us ( umstadter ) has demonstrated electron beams of a few million electron - volts whose “ brightness ” ( in essence , the concentration of particles in the beam ) exceeds that of beams made by conventional accelerators , mainly because the charges bunched in one pulse of the beam have less time to blow it apart by its own electrostatic forces
例如乌姆斯塔特（本文作者之一）便曾展示过，具有数百万电子伏特的电子线束之亮度（基本上，即是线束内的粒子浓度）超过了传统加速器产生的线束，因为脉冲内束在一起的电荷根本没时间以自身的静电把别人挤开。 |
| 9. | Whereas string theory cannot be tested directly ? it deals with energies that cannot be created in the laboratory ? connes points out that noncommutative geometry makes testable predictions , such as the higgs mass ( 160 billion electron volts ) , and he argues that even renormalization can be verified
例如，弦论无法以实验来检验，因为弦论所涉及的能量太高，物理学家在实验室中造不出那麽高的能量，但是巩讷指出非可换几何所做的预测，譬如希格斯质量（ 1600亿电子伏特） ，却是可以检验的，他说甚至重整化也可以证实。 |
| 10. | Ii ) energies of the sputtered atoms vary mainly from several to several teens ev , with few atoms " energy relatively high ; the emitting positions of the sputtered atoms are close to the corresponding incident ions ( in the order of angstrom ) ; the sputtered atoms are emitted mainly normally , and few are slantways ; energy and angular distributions of sputtered atoms are influenced by the energies and incident directions of incident ions , but the angular distributions are not influenced by the incident energy very greatly
Ii )溅射原子的能量一般集中在几个到十几个电子伏特的范围内，在高能量区域也有所分布，但数量很少;溅射原子的出射位置就在离子入射位置的附近(埃数量级) ;溅射原子的角度在垂直方向和斜射方向都有所分布，但以垂直出射为主;溅射原子的能量、角度分布受到了入射离子能量、角度的影响，但入射离子能量对溅射原子的出射角影响不大。 |
