介绍了一种基于热声理论、新型的混合物分离方法,对混合物热声分离法的基本原理和利用热声分离混合物的典型装置做了详细的介绍。该方法对于一些组分沸点相同或密度大小接近、用常规方法难以分离的混合物可能有很好的分离效果 A new method of mixture separation based on thermoacoustic theory is introduced. The basic principle of thermoacoustic separation of mixture and the typical device for separating mixtures by thermoacoustic spectroscopy are introduced in detail. The method for some components boiling point of the same or close to the size of the density, with conventional methods difficult to separate the mixture may have a good separation effect
