通过与Zeta Per、Zeta Oph、Chi Oph和Omicron Per前方云的观测数据进行比较，探讨了星际云稳态模型的局限性。改进的云模式被构造来再现观测到的H和H2（J）柱密度的几条视线。与以前的模型的主要区别是在H2线的自屏蔽的治疗。对以前的模型的其他改进进行了讨论。
The limitations of steady state models of interstellar clouds are explored by means of comparison with observational data corresponding to clouds in front of Zeta Per, Zeta Oph, Chi Oph, and Omicron Per. The improved cloud models were constructed to reproduce the observed H and H2(J) column densities for several lines of sight. The main difference from previous models is the treatment of self-shielding in the H2 lines. Other improvements over previous models are discussed as well.
