Cell survival curves have been obtained for Escherichia coli B (E. coli B) after the sonication of suspensions of the bacteria with continuous wave ultrasound at a fixed frequency of 2 MHZ between peak intensities of 8.7 and 2.25 W cm-2. It was found that under suitable conditions the survival curves were reproducible and it also was found that there was a clear relationship between the rate of inactivation and the peak acoustic intensity of the ultrasound. There appeared to be a lower threshold of peak intensity below which no inactivation was observed.
在用频率固定为2兆赫兹的连续波超声对大肠杆菌B（E. coli B）菌悬液进行超声处理后，获得了其细胞存活曲线，超声峰值强度介于8.7和2.25瓦/平方厘米之间。结果发现，在合适条件下，存活曲线具有可重复性，并且还发现失活速率与超声的峰值声强之间存在明确关系。似乎存在一个峰值强度下限，低于此下限未观察到失活现象。
