摘要 利用初等数论的方法,系统地讨论了平面内圆上的有理点、整点的个数。得到:圆心不是有理点的圆上存在有理点充要条件;圆上整点的计数及构造方法。给出了部分例子对关键定理及推论予以阐释。 In this paper,rational points and integer points on a circle are studied.By classifying circles with rational and irrational centers,we propose some methods for counting the number of rational or integer points on different types of circles.In addition,we illustrate some of the theorems and corollaries with examples.
