| Abstract: | X0 as different types of discontinuous point of sectional-continuous function f（x） is discriminated in this article. And the sufficient condition of whether its original function F（x） is continuous at the point x0 is given here. Meanwhile, the interrelations of integral constants at different sections are revealed, which provides theoretical basis for the calculation of indefinite integral of sectional function. |
