一、引言医药上常遇到调节分散系统之分散相与连续相的配比或分散质浓度等实际问题。常用计算方法:稀释公式、平均浓度公式、混合比例法、交叉法,也有用诺模图或相似三角形以运算。前一类方法一般步骤繁多,欠简便,若无对数表配合常常会算错;后一类则往往因为方 I. Introduction It is often encountered in medicine to adjust the dispersion of the dispersed phase system and the continuous phase ratio of the concentration or other practical problems. Commonly used calculation methods: dilution formula, the average concentration formula, mixed ratio method, crossover method, also useful nomogram or similar to the operation of the triangle. The former method generally has many steps and is not easy to use. If there is no logarithmic table, it will often be wrong; the latter one is often because
