On the aspect of error compensation, the system using the geometric average sound pressure instead of the arithmetic average sound pressure to get the sound pressure of the measurement point. This method not only reduces the high frequency error in the sound intensity measurement, which compensates the finite difference approximation error, but also greatly reduces the computation of the sound pressure spectrum.

误差补偿方面，课题采用几何平均声压代替通常的算术平均声压来计算双传声器法的声场声压值，这样不仅可以有效的减少声强测量中的高频误差，对有限差分误差起到了补偿作用，而且还大大减小了声压谱计算中的计算量。

The results showed that,the sound pressure level increased significantly when narrow transverse groove was used;the effect of speed on the sound pressure level was greater than loading;the noise of S-shaped straight groove was lower,and the difference of sound pressure level between positive and negative rotation was small;the sound pressure level of 15° oblique groove was higher than 0° and 15° alternate groove,but the difference of sound pressure level between positive and negative rotation of 0° and 15° alternate groove was bigger.

Human brain function similar to the central processing unit installed on the motherboard on the above, it has a superhuman memory and rapid calculation function of precision, it can be scheduled in accordance with the procedures for people to not hesitate to complete the instruction, as well as network traffic as the memory, it can provide more paths and channels to the computer, the faster the computer more efficient, to let the computer voice would also like to assemble a deal with the sound card sound files, as the screen reader software At the same time, prompted the need for sound playback, sound card, therefore the request is relatively high, the best selection of full-featured dual-channel sound card.

类似人脑功能的中央处理器就安装在主板上面，它具有超人的记忆能力和精确快速的运算功能，它能够按照人们预定的程序毫不犹豫地去完成各项指令，还有就象交通路网的内存，它能够提供更多的路径和通道给计算机，使得计算机的运算速度更加快捷，要让计算机能够发出声音还要装配一个处理声音文件的声卡，由于读屏软件所需要同时播放提示声音，因此声卡的要求比较高，最好选用功能齐全的双声道声卡。

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。
