| 摘 要： | 本文用解析方法研究了在均匀磁场中入射离子在矩形空心阴极中的分布。结果表明当空心阴极的深度和宽度接近的时候，入射离子在一个侧面上的分布不受另一个侧面的影响，同时受阴极深度影响的在底面上的离子分布及粒子数量都从阴极的中心到边缘而单调地降低。

| Abstract: | Incident ion distribution inside a rectangular hollow cathode in a uniform magnetic field is studied analytically. The analysis shows that the ion distribution on one sidewall is not interfered by the other sidewall when the depth and width of the cathode are equal, and the ion distribution on the bottom surface related to the depth of the cathode and the number of ions on the bottom surface decrease monotonically from the centre to the sidewall. |
