| 中文摘要: |
| 利用一种简单的压力装置，制作与PZT压电晶片匹配的背衬块，最高声阻抗可达25．1×106kg·m-2·s－1用于试制窄脉冲探头，可以实现1.5周期的脉冲． |
| 英文摘要: |
| Described is the development of high-impedance backing composites (up to 25.1×106 kg·m-2·s-1) by using a kind of simple compressor. Working in cooperation with PZT-5 or PZT-6, it gives a pulse width of 1.5 cycles. |
