摘要
图书作为精神文化产品,一旦出版,即与其他商品一样有一个销售过程。这包括从样书发行,直至该种图书售完。仔细研究这个过程是较为复杂的。本文试图通过数学模型来描述读者数、图书销售数和销售速度之间的数量关系,并以微分方程来阐述。文中的I(t)、S(t)、R(t)分别表示的三种函数,简写为I、S、R。
In the paper, two mathematical models have been set up to describe thequantitative relation between the number of readers and sold books and thesale Speed of books. The quantitative analysis of the book sale have beenmade by the methods of differential equation.
