有关成本问题漫谈

Discussion on Problem of Cost

最新出版的经管类数学书中有的在总成本函数叙述上容易使人们产生误解;有的把总成本的平均变化率写成平均成本,记法也混乱。通过对上述两种情形加以阐述,达到澄清概念,统一记法,前后知识连贯,触类旁通之目的。

In some mathematic books of economy and management published recently, the statement about function of total cost tends to make readers misunderstanding. For example, the average change rate is written as average cost. Furthermore, the notations are also in confusion. The article expounds the situations mentioned above so as to clarify the concepts, unify the notations, link up the knowledge and understand related things.
