摘　　要：对相关文献的1 806个MgII(279.6,280.3 nm)吸收系统的样本进行了统计分析.发现MgI(285.2nm),FeII(238.2 nm),FeII(258.7 nm)和FeII(260.0 nm)吸收线也常出现在MgII(279.6,280.3 nm)吸收系统中,并且,与MgII(279.6 nm)的吸收强度相比,它们的吸收也较强,但是MnII(257.6 nm)和TiII(324.2 nm)吸收线比较少出现在MgII(279.6,280.3 nm)吸收系统中,并且很弱.A statistical analysis of 1 806 absorbers in the related paper has been carried out. It was found out that the absorption lines of Mg I （285.2 nm）, Fe II （238.2 nm）, Fe II （258.7 rim） and Fe II （260.0 rim） were detected in the same Mg II （279.6, 2803nm） absorption system, and had large strongly of absorptions compared to that of Mg II （279.6 nm）. However, the absorption lines of Mn II （257.6 nm） and Ti II （324.2 nm） were rarely observed in the same Mg II （279.6, 280.3 nm） absorption system, and often regarded as very weak lines compared to Mg II （279.6 nm） absorption line.
