| 中文摘要: |
| 讨论了超声换能器的几种激励方法，分析了三种常用激励方法在激励高颖超声换能器时的特点及其局限性．我们用雪崩MARX电路制作的单极窄脉冲能有效地激励频率高达100MHz的换能器并取得了较好的结果． |
| 英文摘要: |
| Methods electrically exciting an ultrasonic trandcer are discussed. Three kinds of commonly used high-frequency exciting methods are analysed for their merits and limitations. The chosen MARX circuit based on avanlanche mode gives an efficient unipolar pulse with satisying result(amplitude greate than 400 V with rise time less than 5 ns) on a 100 MHz ultrasonic trandsducer. |
