利用流体理论电子平衡模型，对二维不考虑带电粒子碰撞的激光分离同位素（ＡＶＬＩＳ）离子引出过程进行了数值模拟，包括对不同收集方式进行了模拟和对比，研究了离子引出过程中的物理机理及物理量的空间分布特点，表明等离子体电位略高于阳极电位，并在离子引出过程中基本保持不变；电子温度越高等离子体电位越高，离子引出时间越短；对称收集方式的离子引出时间短且离子逃逸量也少。
The electron equilibrium model of fluid theory was used to simulate the two-dimensional extraction process of laser-separated isotope (AVLIS) ions without considering charged particle collisions, including the simulation and comparison of different collection methods, and the physical mechanism of ion extraction And physical properties of the spatial distribution of the characteristics that plasma potential slightly higher than the anode potential, and in the process of ion extraction remained essentially the same; higher electron temperature plasma potential higher ion extraction time is shorter; Symmetric collection mode ion extraction Short time and less ion escape.
