用快速流动法研究了红细胞的氧合速度，方法是改变通过观察管的流速，血液样品来自5名正常人。流速固定在294、147和74 cm·sec-1三个不同水平。在SO_2浓度为0 ~ 70%的范围内测定了氧合速度，用MOCHIZUKI的速度因子表示氧合速度，在低流速范围内，氧合速度随流速的增加呈线性增加，而在高流速范围内，氧合速度的增加速率逐渐减小。从实验事实中得出以下结论：O2扩散到红细胞中主要受到边界层的抵抗，边界层具有受细胞表面周围对流强烈影响的传递系数。
The oxygenation velocity of the red blood cell was studied by means of a rapid flow method by varying the flow velocity through an observation tube with blood samples from five normal human subjects. The flow velocity was fixed at three different levels of 294, 147 and 74cm·sec-1. The oxygenation velocity was measured over an SO2 range from 0 to about 70% and the velocity was expressed by the velocity factor described by MOCHIZUKI.The Fc value increased with the flow velocity linearly at a low velocity range, but at a higher velocity range the rate of its increment decreased gradually. From the experimental facts the following conclusion was derived: The O2 diffusion into the red blood cell is resisted dominantly by a boundary layer having a transfer coefficient which is strongly affected by convection around the cell surface.
