Carbon black particles had propensity to redeposit on the fiber surface or inside the fibers and those redeposited ink particles were very difficult to be dislodged. The redeposition of carbon black particles whose size ranged between 0.5μm and 3μm was the main reason for brightness loss.

水性油墨粒子易于沉积在纤维表面或细胞腔内，而且一旦油墨粒子沉积于细胞腔内便很难被去除，直径在0.5～3μm之间的水性油墨粒子再沉积于纤维表面或内部是导致白度降低的主要原因。

The dispersion mechanism of the dispersants was analyzed by testing the Zeta potential of the dispersion phase in the dispersion medium.

Although the dispersion of particles with the Stokes numbers far less than or of the same order of 1 are insensitive to the changes of inlet velocity differences, the dispersion of particles with Stokes number much larger than the order of 1 are influenced by the coherent structures under U〓/U〓=α=0, where α=0 means the particles are released into the flow in stationary state.

在目前国内开展三维N-S方程大涡模拟还非常困难的情况下，本文以两相平面湍射流为对象，不采用流动对称性假设，成功地用大涡模拟方法预报了平面湍射流拟序结构的产生、发展及大涡的合并破碎全过程，和F.O。

The minimum fluidization velocity has a minimum value when the frequency of sound waves is 120Hz and it will decrease as the sound pressure level increases. The degree of sound attenuation will increase while bed material is higher and the fluidization quality of fine particles will become poor and the minimum fluidization velocity will increase. Compared with TiO2, the SiO2 fine particles have a better quality of fluidization at the same fluidized conditions.The cluster/subcluster model and oscillators model are used to describe the fluidization characteristics of fine particles in a sound-assisted fluidized bed. The theoretical calculations show that the minimum fluidization velocity umf is decreased with the SPL increased at the same frequency of sound and the quality of fluidization is better.

论文还系统的考察了声压和频率对纳米SiO2和TiO2颗粒流化特性的影响，结果表明：在频率一定的情况下，声压越高，流化床中形成的聚团尺寸越小，最小流化速度越低，流化质量越好；当声压低于120dB时，声场对超细颗粒流化特性的影响减小，当声压大于130dB时，则能显著改善流化效果，使流化床内的颗粒聚团明显减小，最小流化速度明显降低，粉体带出减小；声压一定，频率为120Hz左右时，最小流化速度最低，此时流化床中形成的聚团尺寸最小，流化效果最好；超细颗粒达到较好的流化状态存在一个最佳频率范围，随着声压增高，这个频率范围将增大。

The results show that as for the as-cast castings, eutectic Si particles are characterized as fibrous or long acicular shape as well as in homogenous distribution, and the impact absorbed energy varies from 1.17 to 2.35J. After T6 heat treatment, the eutectic Si particles become small granular or short bacilliform, and the aspect ratio and area fraction of Si particles decrease evidently. The energy of the T6-treated castings is 1.45-3.80 J, which is higher than that of the as-cast castings. Furthermore, the fracture mechanisms of different regions in the castings were analyzed and discussed.
