定积分中的间断点与原函数存在性问题之探讨

Study on the Existing Nature of Discontinuous Point and Primitive Function in Definite Integral

通过对牛顿-莱布尼兹公式条件与结论的分析,深入研究了定积分与原函数两者存在性间的关系,从如何正确利用公式入手,做了较为深入全面的分析,有利于对定积分的研究,探讨了函数与原函数中出现间断点的问题。

Through analyzing the condition and conclusion of Newton-Leibniz formula ,we made a thorough study of the relation of existing nature between definite integral and primitive function. We especially researched the problem of discontinuous point appearing in function and primitive function thoroughly by making use of formula.
