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

The rules of the cold-test characteristics changing with helix pitch are also studied and it turns out that, with increasing helix pitch, the phase velocity increases linearly, the interaction impedance changes nonlinearly and the attenuation constant decreases nonlinearly. At the same time, with the limitation of the synchronism between the electron beam and the electromagnetic wave, the change of pitch is small and therefore an approximate linear relation can be introduced.

研究表明：相速几乎随螺距增大而线性变大，互作用阻抗与螺距是非线性的关系，衰减常数随螺距增大而非线性地减小；由于在维持电子注与电磁波速度同步的限制下，螺距变化的幅度不可能很大，因此可近似按线性关系来处理互作用阻抗及衰减常数与螺距之间的关系。
