Alternative proofs for the superadditivity and the affinity (in the large system limit) of the usual and some fractional Fisher informations of a probability density of many variables are provided. They are consequences of the fact that such informations can be interpreted as quantum kinetic energies.

关于费舍尔信息的两个属性

提供了关于超加和性和亲和力（在较大的系统范围内）的替代证明，这些证明包括许多变量的概率密度的常规和一些分数Fisher信息。它们是这些信息可以解释为量子动能的事实的结果。
