确定某些类星体相关元素丰度的主要障碍是：（1）缺乏精确测量的氦谱线强度;（2）在相关的气体和辐射密度下，双电子复合（即C（+3）+ e（-）产生C（+2））被抑制的程度不确定。本文给出了一些计算结果，试图减少后者的障碍。
Major obstacles to determining certain elemental abundances associated with some quasars are (1) a lack of accurately measured helium line intensities, and (2) uncertainty about the extent to which dielectronic recombination, i.e. C(+3) + e(-) yields C(+2), is suppressed at the relevant gas and radiation densities. Some calculated results are presented in an attempt to reduce the latter obstacle.
