The conclusion is pointed that the dispersion absolute and infimum decrease when the variables increase.

首先指出了在变量增加条件下，残差绝对值和下确界减小的结论。

In this note, using the spectral theory of linear operators, a spectral representation of infimum of two self-adjoint operators with respect to the logic order is established.

本文利用线性算子的谱理论给出了逻辑序下两个自伴算子下确界的谱表示。

Property of symmetric random variable is discussed by introducing the concept of almost supremum and infimum.

讨论了具有倒对称随机变量的若干性质.
