摘　　要：本文对管式反应器中Casson流体层流流动的停留时间分布进行了理论分析,导出了停留时间分布密度函数的精确数学模型和简化数学模型。在较宽的参数范围内,简化模型与精确模型吻合程度较好。还得出等温管式反应器中一、二级不可逆反应的转化率计算式,并对转化率作了计算和比较。Residence time distribution(RTD) for laminar flow of casson flows in a tube reactor is analysed theoretically, and the exact and simplified mathematical models are derived for RTD density function. The models are in good agreements in a wider range of parameters. Also, formula for calculating the conversion of first-order and second-order irreversible reactions are obtained in a isothermal tube reactor with the function derived. Finally, the comparison is carried out for the conversions calculated.
