The results show that the diffraction patterns for WS2 single phase were observed; the pronounced quantum size effect exists in S-W-S nano clusters, and it enhances the hybridization of different electronic shell obits and formed a closed hollow spherical structure without any dangling bond. In the lubricating process, such a system can maintain its chemical stability and decrease energy dissipation.

分析结果表明：XRD图样显示为WS2相单相；在S-W-S纳米簇团中存在显著的量子尺寸效应，该效应强化了硫原子电子壳层间的轨道杂化，使纳米级的WS2润滑晶体形成了1个没有悬键的、化学性能稳定的中空球体，在润滑过程中，这种结构可使体系保持较强的化学稳定性，能耗降低。
