摘　　要：改革"酸碱溶液pH值计算"传统的教学方法,利用"衔接"的方法推导公式,利用"归纳"的方法增强系统性,分析溶液的类型,根据所给定的条件,选择相应的公式进行计算,从而提高教学效果。The new methods are better than the traditional ones to the PH-value calculation of acid and alkaline solutions such as deriving formulas by using the ＂tandem＂ method and enhancing the systematic recognition with ＂induction＂ method.With the help of these new methods and the correct choice of calculating formulas based on the given conditions,the types of solutions could be analyzed,and in such a way teaching efficiency can be promoted.
