| 4 | A study on effect of sonochemistry in a reverberation field显示文摘In this paper,an ultrasound with frequency of 815 kHz was used to re-search the sonochemical yield in a small-size reverberation field by the methodof fluorescent spectrum analysis.There are two characteristics on the effect ofsonochemistry in the reverberation field:First,the cavitation threshold wasabout 0.3W/cm^2(it was 0.7W/cm^2 in travelling field);Second,when thesound intensity was larger than the threshold,the sonochemical yield increasedas the intensity increased and increased rapidly after the intensity was at1.69-2.13W/cm^2,so that there was a upturned point in the curve of the result(which would tend to saturation in the travelling field).The theoretical analysisshows that the reason of the threshold decrease is that the sound energy densitybecomes high in the reverberation field,and the upturned point results from thedisturbance of the radiation pressure on the liquid surface.Therefore,by exper-iment and theory this paper shows that a reverberation field has to be built forthe higher | WANG Shuangwei(Dep. of Physics.

| 11 | Operating characteristics analysis of a dual-excited full-wavelength piezoceramic ultrasonic transducer显示文摘A dual-excited full-wavelength piezoceramic ultrasonic transducer as a cascade of two half-wavelength sandwich piezoceramic transducers is studied.The relevant parameters' expressions of the figure of merit N for the transducer are derived,and the effects of the structure and material parameters of the transducer on its characteristics are further analyzed by numerical calculation.The results show that when the two piezoceramic stacks are respectively located at the displacement nodes of their own half-wavelength transducers,or the two piezoceramic stacks have the same number of pieces in the case of a certain number of piezoceramic pieces,the figure of merit of the transducer can reach a maximum.With increasing of the number of piezoceramic pieces in a fairly large range,the figure of merit of the transducer slightly decreases,but the force factor of the transducer increases rapidly.The metal materials of the transducer have little effect on its figure of merit.Thus it can be seen that the dual-excited full-wavelength transducer can effectively increase the volumes of the piezoceramic stacks in the case of that the transducer's comprehensive performance has only a little bit of degradation,so it's power capacity and load capability can be dramatically improved,which means the transducer is more suitable for high power and heavy load applications. | LIANG Zhaofeng MO Xiping ZHOU Guangping | 2017 | Chinese Journal of Acoustics2017，36，2： | 0 |

The special shell is provided with amplitude amplification and weighted height amplification effect that is called 'double-amplification' effect. A prototype of the Terfenol-D 'Fish-mouth' flextensional transducer is developed. Theoretical analysis and experiments in lake are showed that the 'Fish-mouth' flextensional transducer has lower resonant frequency: about 1.1 kHz, wider frequency band: Q factor for - 3 dB bandwidth less than 3, transmitting current response level: 182 dB. A free-flooded cavity with compliant material is used to achieve depth capability. | MO Xiping (Institute of Acoustics, The Chinese Academy of Sciences Beijing 100080) | 2001 | Chinese Journal of Acoustics2001，20，2： | 0 |
