This paper deals with the role of serial and parallel inhomogeneity in the study of oscillation mechanics of the lung. Contrasts of lumped and distributed parameter models elucidate the role of wavelength compared with structure length in modeling spatial inhomogeneity. The application of self-consistency theory incorporates both serial and parallel inhomogeneities in explicitly described branching networks, and encompasses within an efficient computational scheme all previously described models of oscillatory lung response. As examples, this theory is employed to elucidate the sources of frequency dependence of airway resistance below 10 Hz and the nature of transpulmonary sound transmission up to 5 kHz.
本文探讨了串联和并联不均匀性在肺振荡力学研究中的作用。集总参数模型和分布参数模型的对比阐明了在模拟空间不均匀性时波长与结构长度相比的作用。自洽理论的应用在明确描述的分支网络中纳入了串联和并联不均匀性，并在一个有效的计算方案中涵盖了所有先前描述的肺振荡反应模型。作为示例，该理论用于阐明10 Hz以下气道阻力频率依赖性的来源以及高达5 kHz的跨肺声音传播的性质。
