The fluctuating deviation of bed voidage and theenhancement index of bed uniformity derived in this study can describerespectively the bed uniformity and its extent. A new criterion of demarcationof uniformity, composed of materialparameter, operating parameters (H0, u/umf) and vibrationparameters, can be used to predicting a suitable range ofbed uniformity.

对空隙率波动偏差的分析表明，振动参数、颗粒物性和操作参数均对床层均匀流化行为有不同程度的影响，且振幅和振动频率越大越能明显提高以小米或玻璃珠为物料的床层的均匀稳定性，而颗粒物性和操作参数直接影响振动能量在床层中的传播。

TEM shows that drying by direct heating might result in hard aggregation of the tourmaline powder, while hard aggregation might be avoided by azeotropic distillation. Raman spectroscopy reveals that there are O_H and C_H on the surfaces of the tourmaline powder obtained by azeotropic distillation, which indicates that butoxy is chemically adsorbed on the surfaces of tourmaline particles, but not adsorbed on those formed by direct drying. X_ray powder diffraction shows that the intensity of diffraction peaks decreases after grinding. There is no damage to the tourmaline crystal lattice in the process of direct heating, azeotropic distillation, or ultrafine grinding.
