【摘要】 分析了返混对化学反应的影响 ,认为文献中的描述存在缺陷 ,通过建立新的数学模型 ,定义了具有普遍意义的返混度概念 ,得出了在管式反应器中有轴向返混存在时一级反应的新的解析解 ,并绘制了返混度与Pe及k·τ间的关系图和反应器内反应物浓度随位置变化的曲线图。更多还原

【Abstract】 In view of the drawbacks in some literatures,a new mathematical model for the confusion in chemical reaction was built up.The concept of confusion was defined and a new analytic conclusion of first order reaction when there is confusion at axial direction in tube reactor was presented.Finally,the chart and graph concerned were drawn.更多还原
