The logarithm correlation between second and third moments of experimental charge distribution is very well reproduced by theory.
理论结果很好地再现了电荷分布实验数据中呈现的条件矩间的对数关联；

The use of moments for image analysis is straightforward if we consider a binary or gray level image segment as a two-dimensional density distribution function.
若把二值图或灰度图看作是二维密度分布函数，就可把矩技术应用于图像分析中。

Equations of mass, momentum and second moments for particulate phase are derived from a particle PDF (probability distribution function) equation in dilute turbulent sediment-laden flows.
