摘　　要：用双膜理论建立了两种气体同时化学吸收的传质 -反应动力学模型 ,并用正交配置法 (OC)对方程组进行了数值求解。通过比较用正交配置法和近似解析法求得的结果 ,证明了正交配置法用于这类问题的有效性 。A mass transfer reaction dynamics model for simultaneous absorption of two gases with chemical reaction in liquid medium is developed based on the film theory model. The method of orthogonal collocation (OC) is suggested for solving the model. Comparisons are performed between the results obtained by OC numerical solutions and those by approximate analytical solutions in order to discuss the validity of OC method. Wide range of parameter values is chosen to show the effect of the presence of one gas on the rate of absorption of another.
