摘　　要：通过实验发现 :在测量范围内 ,声透射损失随含气量线性增大 .在气泡大小、分布一定的情况下 。The result of the experiment indicated that the sound transmission loss linearly increased with the increase of concentration of entrained air. On conditions that the size and distribution of bubble were unchanged, the concentration of entrained air might be determined by this phenomenon.
