| 摘 要： | 本文从理论上导出了直接接触型氧合器中血液化学吸收与物理吸收氧传质系数间的关系式：在φ１００ｍｍ的填料式氧合器中，分别对猪血和生理盐水吸收氧的传质系数进行了测定。实验结果表明，在填料式氧合器中，血液和生理盐水吸收氧的传质系数满足上述关系。

| Abstract: | A simplified mathematical model describing mass transport of oxygen was presented in study of direct contact oxygenator.By using variable replacement method.the model was solved and a theoretical expression of mass transfer coefficient of oxygen obtained as follows:At the same time,a relation of mass transfer coefficient between chemical and physical absorption was found:Pig blood and physiological saline solution were used to study the mass transfer characteristics of blood oxygenation in a 100mm packed column,and results showed that the relation above-mentioned could be also used in study of packed column oxygenator. |
