类星体吸收线红移系统证认方法的进一步探讨

本文对崔振兴和陈建生等人所提出的类星体吸收线红移系统证认方法作了进一步探讨。指出了方法的局限性及改进的办法;也指出了有待于今后继续研究的问题;并将改进后的方法应用于类星体PKS 0528-250的光谱分析中,得到了它的吸收线红移系统有:Z_a=2.8110,2.8130,2.5375,2.1410。这和Morton等(1980)所得的A_1,A_2,B,C红移系统一致。另外,我们又得到的新系统是Z_a=0.0345,0.0065。Chen和Morton(1984)所得到的D_1,D_2,E,F,G系统,我们未发现。讨论了产生这种差别的原因。

A Further Study on the Method of Identifying Absorption Line Systems in QSOs Spectra

The method of identifying absorption line systems in QSOs spectra suggested by Cui and Chen et al. in 1983 (see references 9 and 10) has been further developed in this paper. Confinements of the method and their improvements are discussed. Some problems which need to be continually studied are pointed out. The improved method based on this paper has been applied on PKS 0528-250 for identifying absorption line systems in its spectrum. We obtained some new absorption line systems Za = 0.0065 and 0.0345 besides the systems Za=2.8110. 2.8130, 2.5375 and 2.1410 which are consistent with the systems Al, A2, B and C given out by Morton et al. (1980). But however, the systems D1, D,, E, F and G obtained by Chen and Morton (1984) have not been found by us. At last, the reason of this discrepancy has been discussed.
