Absorption line

There are a lot of absorption lines in spectra of QSOs.

类星体光谱中有大量的吸收线 ,它们或者产生于与类星体本身有联系的气体云 ,或者产生于类星体和观测者之间的吸收系统。

6 in which the full-line histogram shows the emission-line redshift distribution of the ratio of the number of QSOs having close-by absorption lines to the number of absorption QSOs in ge.

0的间隔，有明显的突出性，如类星体发射线红移值和吸收线类星体数都在zem＝2为峰值，各间隔中有吸收线≥3条和≥6条的峰值也在zem＝2等。

In this paper we present an unbiased homogeneous CIV absorption line sample of 228 QSOs, which include most of the published QSOs spectra data involving CIV absorption lines with high or medium resolution.

高红移活动星系核的环境是目前亟待研究的领域,与类星体发射线区成协的吸收线系统有可能被使用。

We investigated the relation between the Lyman-α emission and Absorption lines of quasar pairs by exploring possible correlation between the equivalent widths of the two kinds of lines.

通过探究类星体对的Lyman-α的吸收线和发射线的等值宽度,研究了它们之间可能存在的相互关系。

It is particularly important to study the absorption lines of quasar.

类星体吸收线的研究具有重要意义。

The effect of model parameters on the sorption and desorption curves was simulated.

用Voigt蠕变模型和Flory-Huggins混合模型分别计算溶剂在高分子膜中吸收和解吸过程高分子的蠕变及与溶剂混合的吉氏函数变化,结合质量守恒建立了一个小分子在玻璃态聚合物中吸收和解吸的传递模型,模拟计算结果和对实际系统的吸收和解吸曲线的关联和预测结果表明,模型能很好地描述实验中常遇到的S形吸收曲线,并能根据吸收曲线的实验信息预测相应的解吸曲线。

The sigmoid sorption curves and corresponding desorption curves can be satisfactorily simulated with this model and can be extended to the Fickian and case II diffusion.

该模型能很好地模拟具有Ｓ形的吸收曲线及对应的解吸曲线，并可推广应用于费克扩散和Ｉ类扩散情形；用不同相对压力下的两条实验吸收曲线可获得小分子在高分子膜中扩散系数随浓度变化的关系，并可预测其它相对压力下的吸收和解吸曲线。
