摘要
讨论了有界变差数 f(x)在闭区间上连续的充要条件以及函数 f(x)在闭区间上有有界变差的充要条件。
A discussion is made of the continuously sufficient and necessary conditions of the bounded variation f(x)on the closed interval in the paper.Furthermore,when the function f(x)has the bounded variation on the closed interval,a sufficient and necessary condition is also dis- cussed.
