摘要
通过作平衡曲线的弦，导出了计算精馏塔理论塔板数的显函数关联式，并确定了式中常数Ｃ、Ｅ的值．该式直接将理论塔板数和操作参数关联，在参数变化较大的范围内，其计算结果与Ｓｍｏｋｅｒ方程的精确解一致．
The correlation for calculating the number of theoretical Singes and the feed point in the distillation column are developed by introducing the constants C、E and the values of constants C、E are Selected in this paper. The results coincide with the exact solution calculated by smoker's equation even if the operating P8rameters varied in wider range. when C=E=1.00, this correlations in this paper and the literature [12] are the same, thus the fomer is a general form of the latter.
