超声波的声强、作用时间、温度和传声介质对氧化脱铬率均有影响。
It was found that the dechroming rate depends on sound intensity of ultrasound , time of reaction , temperature and medium .

声学参量（包括声速、声衰减系数等）是由传声介质的组织决定的，不同组织状态与其声学参量有着直接的联系。
As well know , ultrasonic wave transmitting in material structure decide its acoustic parameters ( such as velocity and attenuation coefficient of sound ), and there is a direct relationship between acoustic parameter and different states of microstructure of material .
