摘　　要：推演了在精馏计算中相对挥发度α的选择对最少理论塔板数Nm 及最小回流比Rm 的决定影响。从基础理论上阐明了α的选用原则。并且对几个经典理论公式的相互关系作出了解释。The decisive influence of relative volatility α chosen in calculation of distillation on the minimum number of theoretical plates N m and the minimum reflux ratio R m is given by derivation and deduction.The principle of choosing α is expounded on the basis of basic theory.In addition the correlation of several classical theoretical equations is explained with cogency and relevance.
