The results show that static order of Ag atoms increases, and anharmonicvibration of Ag atoms becomes stronger when Ag particle size decreases.
结果表明，随着纳米银颗粒尺寸的减小，银原子的静态无序度增大，非和谐振动加剧。

Considering atomic anharmonicvibration, the authors have figured out the expression of free energy and relaxation of single-domain ferromagnetic granule in magnetic field.
结果表明：原子的非简谐振动会影响单畴铁磁粒子的自由能，但是不会影响弛豫时间。
