The VFD model can be used not only in short time vibration analysis but also in long period storage relaxation calculation so long as different parameters are adopted.
因此采用不同的参数，VFD模型既可以用于短时间内的振动响应分析，也可以用于长时间的储存应力分析。

Considering atomic anharmonic vibration, 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。
