中文摘要:
      文章分析了已有方法制作高阻抗背衬材料的不足,阐述了制作高性能背衬材料的新方法。新的高阻抗背衬材料,声衰减性能优异,材料的结合力高。该材料应用于制作2.8MHz窄脉冲探头,带宽达到120%以上。
英文摘要:
      The deficiency of the existing high impedance backing composites is pointed out and a new technique for manufacturing high impedance backing composites,which give better acoustic attenuation performance,is illustrated.The immersion probe with new high impedance backing provides a broad band of more than 120%.
