论文摘要
我们提出了在实际线路上实现函数的必要条件，使其成为概率度量的特征功能。该声明是根据谐波函数和完全单调的功能给出的。
We propose a necessary and sufficient condition for a real-valued function on the real line to be a characteristic function of a probability measures. The statement is given in terms of harmonic functions and completely monotonic functions.
