Abstract
Streamlining of air flow in the upper airways and trachea has been investigated by inhaling 81m krypton through each side of the nose separately and counting over the lung fields with a gamma camera. 81m Kr inhaled through one nostril was uniformly mixed in the air stream by the time the carina was reached. Gas mixing occurs probably by a combination of diffusion and turbulent flow.
摘要
通过分别从两侧鼻孔吸入81m氪并使用γ相机在肺部区域进行计数，对上呼吸道和气管中的气流流线化进行了研究。当气流到达隆突时，通过一个鼻孔吸入的81m氪已在气流中均匀混合。气体混合可能是由扩散和湍流共同作用的结果。
