平均吸声系数 meaning in English
average sound absorption coefficient
Examples
- Average sound absorption coefficient
平均吸声系数 - The result shows that average absorption coefficient and noise reduction coefficient separately equal to 0 . 58 and 0 . 60 , and fine property of sound absorption at middle - low frequency
结果表明材料的平均吸声系数和降噪系数分别达0 . 58和0 . 60 ，且材料的中低频吸声性能优良。 - The average sound absorption coefficients of larger grains are smaller than the small grains in general . the properties of sound absorption coefficient of grain are in close relationship with the shape and size of kernel , and have no relation with the texture of solid grain
大颗粒粮食的平均吸声系数普遍较小颗粒的平均吸声系数小，颗粒大的随厚度继续增厚，平均吸声系数增加的趋势却很弱，而颗粒小的随厚度增厚，其平均吸声系数一直呈增大的趋势。
