| 摘 要： | 研究了通孔多孔铝合金的超声衰减性能。结果表明：通孔多孔铝合金在1～10MHz范围内是一种具有良好超声衰减性能的轻质材料，超声衰减系数a随孔径d的减小、孔隙率Ps减小和比表面积Sv的增加而增大。

| Abstract: | Ultrasonic attenuation capacity of porous Al alloy with high specific strength was studied. That alloy is a light material with good ultrasonic attenuation capacity between 1- 10 MHz. Ultrasonic attenuation coefficient a of porous Al alloy increases with decreasing pore diameter d, with decreasing porosity Ps and with increasing specific surface Sv. |
