查询词典 ultrasonic

ML dichlorovs(30 mg/L) is oxidized by ultrasonic in 100 mL beakers. When power is 200 W,600 W and 800 W,the removal is low,for the largest removal is less than 20% at the treatment of 60 min, while the removal is 48% when power is 1000 W. On the mean while, cost raises a lot. Consequently, treatment of dichlorovs by ultrasonic is worthless.

超声波法在频率20 kHz，声强为0.3 W/cm2，0.9 W/cm2和1.4 W/cm2（对应的超声功率分别为200 W，600 W和800 W）的条件下处理60 min时的敌敌畏的最大去除率都不超过20％；声强为1.7 W/cm2（1000 W）处理60 min时去除率达48％，但此时处理成本较大，不具实际应用价值。
