查询词典 sound value

Based on the prior information obtained by qualitative inversion, the two stages inversion method was put forward. That is, the first stage is that distinguishing the high-quality element and non- high-quality element, and determining the initial iteration value of element sound velocity reasonably. The second stage is that treating differentially the constraint weights of the high-quality element and non- high-quality element, and then quantitatively inversing the final sound velocity distribution. The results of two concrete specimens indicate that the two stages inversion method can inhibit artifacts effectively and has better defect identification effect than normal one stage inversion.

在获取定性反演先验信息的基础上，提出了两阶段反演的方法：第一阶段，区分优质像元和非优质像元，合理确定像元声速的迭代初值；第二阶段，区别对待优质像元和非优质像元的约束权重，定量反演最终的速度分布。2个混凝土试件的模型试验表明，两阶段反演能有效抑制伪像，具有比常规的一阶段反演更好的缺陷识别效果。

The agglomerations sizes of fine particles in the fluidized bed are smaller under higher SPL. The sound waves have little effect on the agglomerations when it is under 120dB. But the agglomerations sizes will be dramatically reduced to 180μm from 720μm when the SPL is above 130dB. The umf has a minimum value at an appropriate frequency of sound and a good quality of fluidization can exist in a greater ranges of frequency of sound when the SPL is higher.

当频率高于120Hz，流化床中形成聚团尺寸随着频率的增加而增大，最小流化速度也随着频率的增加而增大，当频率低于120Hz，流化床中形成聚团尺寸随着频率的减小而增大，最小流化速度也随着频率的减小而增大；料层越高，声波的衰减越大，超细颗粒的流化效果越差，最小流化速度越大。

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。
