一、引言固体颗粒分散在液体中形成的混合物称为悬浮液.不少学者从事过研究悬浮液声特性的工作,其中理论方面有Epstein, Urick, Biot, Ahuja, McCann,唐应吾,孙承维等.在实验测量工作中有Urick, Hampton, Blue, 唐应吾,孙承维等等.声波在悬浮液中吸收规律的研究在实际上和理论上都很有意义.因为在自然界中广泛地存在悬浮液,一般说来,江、河以及港湾和大陆架的水体中,含有大量的

I. INTRODUCTION The mixture of solid particles dispersed in a liquid is called a suspension. Many scholars have been engaged in the study of the acoustic properties of the suspension, of which the theoretical aspects are Epstein, Urick, Biot, Ahuja, McCann, Tang Yingwu, Sun Chengwei et al. Urick, Hampton, Blue, Tang Yingwu, Sun Chengwei, etc. The research on the law of sound wave absorption in suspension is meaningful in both theory and theory.Because there is a wide range of suspensions in nature, River, river and harbor and continental shelf water contain large amounts of water
