中文摘要：

用B样条技术计算氢分子离子量子点能级的量子尺寸效应．计算结果显示：当R较小时，能级随R的增加快速下降，量子尺寸效应明显．当R较大时，能级变化速度变缓，量子尺寸效应减弱．当R较小时，E1——D／R曲线上升快；当R较大时，E1——D／R曲线上升变慢．当m=0时，能级对D／R的变化很敏感．当m≥1时，m越大，能量对D／R的变化越不敏感．

英文摘要：

Calculate quantum size effects on Hydrogen molecular ion quantum dot energy level with B- spline technology. The calculated results show： when R is small, Hydrogen molecular ion energy levels decrease quickly with R increasing, quantum size effects on Hydrogen molecular ion energy levels are clear; when R becomes larger, Hydrogen molecular ion Energy levels decrease slowly with R increasing, quantum size effects on Hydrogen molecular ion energy levels are not clear; when R is small, the curves D/R rise quickly; when R becomes larger, the curves E1 D/R rise slowly; when m=0, the energy levels are sensitive to D/R, when ml, the energy levels are not sensitive to D/R.
