Abstract  We have observed the thermodynamic properties of metallic superconductive nano-particles in the grand canonical ensemble; and the level distribution and the level correlation between the discrete electronic energy levels are considered in the calculation of the electronic spin susceptibility of the ensemble numerically. The quantum effect, even--odd effect and other special effects existing in the metallic nano-particles are also studied in this article.
Keywords:  nano-particles      random matrices theory      spin susceptibility
