在容量分析中,百分含量随标准溶液的浓度、消耗的毫升数、检体的克当量以及所取的检体量而异。由于变数过多,图解法求含量尚不普遍。即使有亦多将其中变数固定一部分,因而使用不广。这里将根据乘法共线图原理设计而成的一张适用于直接滴定的百分含量计算图介绍于下。若先经换算,亦可应用于间接 In volume analysis, the percentage varies with the concentration of the standard solution, the number of milliliters consumed, the gram equivalent of the sample, and the amount of sample taken. Due to the excessive number of variables, the graphical method is not yet universal. Even if there is more than one fixed part of the variables, it is not widely used. Here, a percentage calculation chart suitable for direct titration, designed according to the principle of multiplicative collinear diagrams, is introduced below. If it is converted first, it can also be applied indirectly
