摘　　要：在介绍了分形理论发展过程的基础上,给出了分形的定义、分形维数计算的多种理论模型,并分析了不同模型之间的区别与联系.总结了分形理论应用于土壤颗粒物、泥沙颗粒、大气颗粒物、地表灰尘、固体燃料燃烧或固体废物焚烧、岩石力学颗粒物领域所取得的主要研究成果和有待于进一步解决的问题,指明了分形理论为研究固体颗粒物的物理与化学特性提供了新的方法与手段,具有广阔的研究与应用前景.On the basis of introduction of the development process of fractal theory,this paper gives the definition of fractal,a variety of theoretical models of fractal dimension calculation and analysis of the differences and linkages among diverse models.It also summarizes the achieved major research results,for the fractal theory is applied to the soil particles,sand particles,atmospheric particulates,road dust,solid fuel combustion or solid waste incineration and rock mechanics.The problems which need to be further resolved are raised.Fractal theory has a broad prospect of research and application,for it provides new methods for the study of solid particles of the physical and chemical characteristics.
