Simplier and more efficient ion extraction methods for atomic vapor laser isotope separation AVLIS were evaluated using a 2-D electron-equilibrium model to compute and compare three electrostatic methods the parallel electrode method, the Π type electrode method, and the improved M type electrode method.
为探索用于原子蒸气激光同位素分离AVLIS的简单有效的离子引出方法,用二维流体理论电子平衡模型计算比较了3种静电场方法平行板电场法,Π型电极法,改进M型电极法计算发现,二维流体理论电子平衡模型并不能很好地描述Π型电极法对另外两种静电场方法,计算了不同外加电压、不同的初始原子密度和不同的目标同位素丰度等条件下的离子引出情况从计算结果可以看出,改进M型电极法不论是从离子引出时间还是从碰撞损失率,都要比平行板电极法好得多当外加电压较高或初始原子密度较高时,这种好处就更加明显因此,改进M型电极法是一种可供实际采用的比较好的静电场方法

We have come to the following conclusions:(1) the existence of the monoatomic layer is conditional, it depends upon the temperature, surface structure and purity of the substrate as well as upon the vacuum environment;(2) the appearance, and sometimes disappearance, of the emission peaks is a problem for further study, and it can not be explained simply by the monoatomic layer...
关于时而能、时而又不能观察到的电子发射峰值,是一个有待于进一步明确的现象,不能简单地用单原子层和偶极子理论来解释;3。吸附了外界原子或分子使电子发射增加的事实,并不是由于偶极矩降低了基底的逸出功,发射的电子来源于被吸附物质的价电子;4。实验证明&L&阴极是Ba-O-W系统,它既不是单原子层,也不是单分子层,也不适用偶极子理论。

Because the rate of ET and HT reactions is determined by the coupling term J, and in long range ET and HT systems the degeneracy of the π orbitals of donor and acceptor is lifted through mixing with the bridge orbitals of appropriate symmetry by an amount △E. Because the △E splittings are proportional to electronic coupling, so we can use the static quantity △E to exploring the dynamic quantity J, and to make a detailed study on the microscopic influence of coupling mechanism in ET and HT process.
由于电子转移和空穴转移反应速率的大小决定于反应的耦合因子,在长程电子转移和空穴转移体系中,给体和受体的简并π轨道由于与饱和桥之间的TB作用而产生一定的分裂能,此分裂能又与耦合因子的数值成正比,因此,我们可以用静态的分裂能数值间接地表征动态的耦合因子,从而详细研究电子转移和空穴转移过程中耦合机理的微观影响因素。
