我国城市扬尘污染形势严峻，细颗粒物是造成大气污染的主要原因，指出了现代城市扬尘的主要根源和危害。从粉尘进入大气的机理和降尘与粉尘的粒径、密度和外力有关的观点出发，提出了固结、润湿和凝聚是降尘机理的主要方法，总结了降尘剂向复杂化方向发展的趋势，列举了近年来降尘剂的主要成果，通过对降尘机理的分析，提出以超强吸水剂为基料，并添加其它物质是今后新型抑尘剂的重要研究方向。
The acute situation of fugitive dust pollution of the cities in China and fine particles are main causes of air pollution.Authors indicate the primary roots and hazard of urban fugitive dust in modern cities. From mechanism how fugitive dust enters into air and depression are relative to its diameter and density and outer force,consolidation and wetting and aggregation are primary methods of depression mechanism.Authors summarize development tendency will transform into complication and list main achievements of dust-depressor in recent years.By analyzing depression mechanism,authors propose using super water-absorber as base material and adding other substances will be a significant study orientation of new dust-depressor in the future.
