Abstract
The lung boundaries exhibit a tight barrier for any insoluble gas; hence boundary conditions for lung gas mixing have to account for the absence of both diffusive and convective fluxes across the lung walls. Scrimshire et al. (1978) have, in contrast, used the less rigid boundary condition that only the net flux be zero. As we believe this boundary condition to be inappropriate for the study of insoluble gases, the results derived appear to have no physiological significance.
摘要
肺边界对任何不溶性气体都表现出紧密的屏障；因此，肺内气体混合的边界条件必须考虑到跨肺壁扩散通量和对流通量均不存在的情况。相比之下，斯克里姆希尔等人（1978年）使用了不太严格的边界条件，即仅净通量为零。由于我们认为该边界条件不适用于不溶性气体的研究，所以由此得出的结果似乎没有生理学意义。
