摘 要 實數(shù)[1]的7個基本定理以不同形式刻畫了實數(shù)的連續(xù)性,它們彼此等價。雖同一定理都可用其它6個定理證明,但有的證明是類似的,本文給出這些定理證明的典型方法。

Abstract The 7 basic theorems of real number [1] describe the continuity of real numbers in different forms, and they are equivalent to each other. Although some other theorems can be proved with 6 other theorems, some of them are similar. This paper gives a typical method to prove these theorems.
