摘　　要：研究了溶质在作圆管层流的微极流体中弥散时的化学反应效应。在Taylor简化假定下,导出了相对浓度分布和等效扩散系数的解析式,并作了数值计算,分析了化学反应率参数α和微极参数九λ,T的效应。This paper investigats the effects of chemical reaction of the dispersion prob-lem where soluble matters are dispersing in micropolar laminar flow through acircular tube. under Taylor's simplified assumption the analytical expressions of therelative concentration distribution and the eguivalent diffusion coefficient are deri-ved. The numerical computations are performed and the effects of chemical reactionrate constant α and micropolar parameters λ, T are analyzed.
