Abstract
In this paper we obtain, that if the partial sums \(\sigma_{q_{k}}(x)\) of a Franklin series converge in measure to a function \(f\), the ratio \(\frac{q_{k+1}}{q_{k}}\) is bounded and the majorant of partial sums satisfies to a necessary condition, then the coefficients of the series are restored by the function \(f\).

富兰克林级数的唯一性定理
摘要
在本文中,我们得到的结果是,如果富兰克林级数的部分和\(\ sigma_ {q_ {k}}(x)\)在度量上收敛到函数\(f \),则比率\(\ frac {q_ {k + 1}} {q_ {k}} \)是有界的,部分和的大部分满足必要条件,然后通过函数\(f \)恢复级数的系数。
