摘要：

A method to calculate the cohesive energy of nanoparticle was developed. When the particle size was large enough, the cohesive energy approach a value of the corresponding bulk material. It was found that decreasing the cohesive energy of nanoparticle means decreasing the strength of the corresponding metallic bond. The lattice parameters of metallic nanoparticle contracted with decreasing their particle size.
