Clock frequencies up to hundreds of kilohertz might be achievable, but don't look for gigahertz-rated organic chips anyt或许可以做到几十万赫兹的时脉，但在短期内别想要有10亿赫兹等级的有机晶片。
Ultrasound frequencies generally range between 20 kilohertz and 50 kilohertz, depending on application requirements. Ult工业超声波清洗常用频率在20千赫到50千赫之间，常用清洗温度在50-80℃之间。
