The code MFEL 1 is applied for short pulse case of, for example, rf linac FELs, FELO is for single mode simulation which can describe the motion in phase space of electrons with energy spread and give some interesting results in short computer running time.

计算表明，在短脉冲情况下，激光强度、品质、增益和能量抽取效率强烈依赖于电子束流强度，对一定范围的能散变化却不敏感；但在长脉冲情况下，上述物理量对能散在同样范围内的变化较为敏感。

In chapter two, using the hydrodynamical equations for electrons and Maxwell equation and through complicated calculation, we finally obtain a set of equations which describe the non-steady and nonlinear interactions between plasma and field in the wake region of a moving body in space.

第二章是从描述电子的磁流体方程和麦克斯韦方程出发，通过计算，最后得到了一组在考虑非静态极限下描述空间飞行器远尾区内等离子体与场之间的非稳态非线性相互作用耦合方程。

The shell structure of electrons reveals that the magic number doesn't exist obviously in the Al n clusters as in the alkali metals. The energy levels are apparently incontinuous in the Al 2～7 clusters.

在Al2～Al7团簇中，能级结构呈现明显的分立特征，费米能级随着原子个数的增加而减小，到Al7时又有所增加，且团簇的能量间隙最小。

In third chapter, We extend Horowitz and Maldacena's proposal about black hole final state to Dirac fields and find that if annihilation of the infalling positrons and the collapsed electrons inside the horizon is considered, then the nonlinear evolution of collapsing quantum state will be avoided.

在第三章中，我们把Horowitz和Maldacena关于黑洞终态的假设推广到了Dirac场并发现如果考虑黑洞蒸发过程中落进视界的负能粒子同黑洞物质之间的湮灭，那么出射态的非线性演化可以避免。

The intervalley distribution of electrons shifts to lower valley as the temperature increases.

电子在各能谷间的分布随温度升高而向低能谷移动。

Furthermore, the changes of intrapair and interpair energies of valence electrons are very great in the different element-formed systems.

计算结果表明不同元素形成的HX(X=Li-F，HBe^+，HBe)体系，其价层电子对内、对间相关能的变化较大，它们之间存在着轨道差别，不宜将其相关贡献归为简单的常数。

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