摘　　要：我们曾经将压电陶瓷粉体复合到传统的吸声降噪材料与阻尼减振材料中 ,制作出了性能更好的新型吸声降噪材料和新型阻尼减振材料 ;而且还发现废品压电陶瓷的粉体与正品压电陶瓷的粉体具有相同的功效[1～4 ] ,分析了它们同样发挥压电效应的原因。The Powder of Piezoelectric Ceramic Is Compounded into Traditional Sound Absorptive Compound or / and Traditional Mechanical Damping Compound by Liang [1-4] . A New Type of Sound Absorptive Compound or / and a New Type of Mechanical Damping Compound with Better Property Is Made. In This Process on Apply, a Same Efficacy on the Powder of Piezoelectric Ceramic Waster and Powder of Piezoelectric Ceramic Quality Goods Is Found. The Reasons Exerting Same Efficacy by Both Is Analyzed.
