利用自行研制的切变波共振吸收力学谱仪测量了颗粒物质(种子、不锈钢珠)的共振吸收力学谱.结果表明,系统的共 振频率具有明显的切位移振幅效应,同时颗粒物质存在特征共振吸收峰.据此计算出颗粒物质的熵力及熵能级差.
The resonant absorption spectra of the particulate matter (seeds, stainless steel beads) were measured by the shear wave resonance absorption spectroscopy instrument developed by ourselves.The results show that the resonance frequency of the system has significant amplitude effect of the shear displacement amplitude and the characteristic resonance absorption of the particulate matter According to this, the entropy and entropy levels of particulate matter are calculated.
