摘　　要：以多釜串联模型为主体,采用示踪法,对不同搅拌速率和不同流体流量下四联釜流动反应器内的返混状况进行了测定,建立了该系统的数学模型。结果表明,搅拌速率及流体流量影响系统返混程度大小,在实际的生产过程中,可以通过调节上述2个可控制的因素,对反应的过程进行控制和调节,使反应向着最有利的方向发展。Using tracer method and CSTR model as the main body, the backmixing in four joint flow reactor under different fluid flow rate and stirring rate were determined to establish the system＇ s mathematical model. The results showed that the fluid flow rate and stirring rate affected the degree of backmixing. In the practical production process, by regulating these two factors, the reaction process could be controlled and regulated and the reaction could develop in the most favourable direction.
