Sound absorbing coefficient was only 0.115.
而制品的吸声系数仅为0 . 115。
In addition the porosity of porous aluminum increasing or pore size decreasing, the sound absorbing coefficient also increases.
另外降低多孔铝合金的孔隙尺寸和增加其孔隙率，均会使多孔铝合金的吸声系数增大。
With light, small coefficient of thermal conductivity, sound-absorbing performance is good, non-flammable, chemical stability is good wait for a characteristic.
具有质轻、导热系数小、吸声能好、不燃、化学稳定好等特点。
