摘要
本文介绍了高频输氧技术中气体输运机理的实验研究结果。用气管-支气管-肺模型来模拟人体呼吸系统,用热线和激光测速技术测量该模型内的气流。结果表明,整流效应和湍流扩散具有关键作用。
This paper describes the results of the experiments on gas transport in high frequency oxygen therapy. The breathing system of human beings was simulated by a physical model of trachea-bronchus-lung which was tested and measured by hot-wire and LDV. The re suits have shown that streaming effects and turbulent diffusion play a key role in gas transport.
