Abstract：
We discuss a category of stable dark matter particles which are weakly interacting and related to the superstructure of the universe.These particles may be degenerate fermions and the bosons near a high temperature state.In both cases,we deduce that the particle mass is ～10 ^－1eV and the absolute value of its chemical potential is <<10 ^－1eV.This result is not in contradiction with the dip phenomena of the ultra high energy primary cosmic ray spectrum at ～10 ¹⁵eV and ～10 ¹⁸eV.
