笔者在数学建模问题的选题、思考与评讲中 ,发现给出数学模型公式的应用题 ,由于单位不同 ,所得数据可能不相等 .在单位处理中争议很多 .下面就数学应用问题中的单位处理问题 ,以文 [1 ]的例 1为例 ,谈谈其解决方法及应用问题数据“单位”的变换法则 .1 以“元”为单位的策略 In the selection, thinking and commentary of mathematics modeling problems, the author found that the application of mathematics model formulae is applied. Since the units are different, the obtained data may not be equal. There are many disputes in the unit processing. The following is a mathematical application problem. Unit handling problem, using example 1 of [1] as an example, talk about its solution and application problem data “unit” transformation rule. 1 The strategy of “meta” as the unit
