摘要

In this paper, we prove that if f is Henstock-Kurzweil integrable on a compact subinterval [a, b] of the real line, then the following conditions are satisfied: (ⅰ) there exists an increasing sequence {X_n} of closed sets whose union is [a, b]; (ⅱ) {fχ_(X_n)} is a sequence of Lebesgue integrable functions on [a, b]; (ⅲ) the sequence {fχ_(X_n)} is Henstock-Kurzweil equi-integrable on [a, b]. Subsequently, we deduce that the gauge function in the definition of the Henstock-Kurzweil integral can be chosen to be measurable, and an indefinite Henstock-Kurzweil integral generates a sequence of uniformly absolutely continuous finite variational measures.
