资料上市这么说的： “DILUTION FACTOR = Concentration BEFORE dilution / Concentration AFTER dilution = Volume AFTER dilution / Volume BEFORE dilution Hence Conc. BEFORE dilution = Dilution factor x Conc. AFTER dilution e.g. If 5 ml of a solution was diluted to 100 ml the dilution factor would be 100 / 5 = 20 For multiple dilutions the dilution factor is the product of the dilution factors for each individual dilution. e.g. If 5 ml was diluted to 100 ml and 2 ml of the resulting solution was diluted to 50 ml the dilution factor would be:- (100 / 5) x (50 / 2) = 20 x 25 = 500 From a practical point of view, the dilution factor for each step is: (Volume of flask) / (Volume of pipette)” 所以我上面的问题中稀释因子应该是10/1=10， 两种方法因该是第二种比较准确， 不知理解是否正确？可是样品如果是固体是按重量计算，不是按体积计算怎么办？
