| 中文摘要: |
| 声凝并机理单独作用对于粒径细微的PM2.5脱除效率有限，并且提高颗粒声凝并脱除效率需要以高能耗为代价.为经济、高效地控制PM2.5的排放，声凝并与其他机制联合作用下PM2.5脱除技术得到发展.介绍了声凝并与其他机制（如电场、外加颗粒、蒸汽、湍流射流、离心力）联合作用下PM2.5凝并脱除技术的理论依据、研究现状、存在的问题.基于此，指出今后对基于声凝并的联合作用下PM2.5脱除技术的研究重点和方向. |

| The removal efficiency of PM2.5 is limited under the single mechanism of acoustic agglomeration.Moreover,high energy consumption is necessary to improve the particle removal efficiency.To control the emission of PM2.5 economically and efficiently,the techniques of combined effects of acoustic agglomeration with other mechanisms for PM2.5 removal have been developed.The theoretical foundations,research status,and the existing problems of PM2.5 removal under the combined effects of acoustic agglomeration and other mechanisms,such as electric field,seed particles,water vapor,turbulent jet flow and centrifugal force are introduced.Based on this,the emphases and direction of future research on acoustic agglomeration-based PM2.5 removal techniques combined with other effects are proposed. |
