摘要翻译：
本文讨论了符号测度（电荷）在描述非凸体线段和弦长分布中的应用。符号分布可以通过非负自相关函数的导数来定义，而非负自相关函数的导数只与物体中点对之间的距离分布有关。本文提出了这种导数的构造性几何解释，并举例说明了与测度理论中通常的Hanh-Jordan分解类似的“正”和“负”元素的出现。该结构还与Dirac和弦法的应用密切相关。

英文摘要：
  In this paper is discussed an application of signed measures (charges) to description of segment and chord length distributions in nonconvex bodies. The signed distribution may naturally appears due to definition via derivatives of nonnegative autocorrelation function simply related with distances distribution between pairs of points in the body. In the work is suggested constructive geometrical interpretation of such derivatives and illustrated appearance of "positive" and "negative" elements similar with usual Hanh-Jordan decomposition in measure theory. The construction is also close related with applications of Dirac method of chords.
