摘　　要：讨论了Lewis因子和Lewis数两个不同概念的区别和联系,Lewis因子,也叫Lewis关系,表示蒸发过程中传热和传质的对比关系;建立了饱和器的一维数学模型,通过数值计算分析了Lewis因子对饱和器数值模拟结果的影响。Tbe Lewis factor and Lewis number are two different concepts. Both the difference and relation between them are discussed. Lewis factor, or Lewis relation, stands for the relative rates of heat transfer and mass transfer in vaporizing process. The mathematic model of saturator is founded. The impact of Lewis factor on simulation of saturator is analyzed through numerical calculation.
