An analysis of previously presented photoelectric spectrophotometry of HII regions (emission-line diffuse nebulae) in the two Magellanic Clouds is carried out with the aid of theoretical nebular models, which are used primarily as interpolation devices. Some advantages and limitations of such theoretical models are discussed. A comparison of the finally obtained chemical compositions with those found by other observers shows generally a good agreement, suggesting that it is possible to obtain reliable chemical compositions from low excitation gaseous nebulae in our own galaxy as well as in distant stellar systems.
借助理论星云模型，对之前发表的麦哲伦云中HII区（发射线弥漫星云）的光电分光光度法进行了分析，这些模型主要用作插值工具。讨论了此类理论模型的一些优点和局限性。将最终得到的化学成分与其他观测者发现的化学成分进行比较，总体显示出良好的一致性，这表明从我们银河系以及遥远恒星系统中的低激发气态星云中获取可靠的化学成分是可能的。
