摘　　要：烧结矿的孔隙是烧结矿的重要性质之一,但由于烧结矿的多相性和不均匀性,使得孔隙结构的研究极其复杂。为了有效地研究烧结矿的孔隙特征,本文采用了压汞测试法进行孔隙测定,应用分形几何的观点完成资料处理,试图从一个全新的角度来分析材料的烧结机理。研究表明,烧结矿的微孔隙具有多层次的自相似性,通过孔隙结构分形维数的计算可以建立烧结矿强度和微孔隙分维的关系,烧结矿的分形特征和烧结过程中孔隙的形成机理有关。The pores in sinter are an important character. Because of sinter＇ s multiphase and asymmetry, the research of pores is very complex. In order to research the character of pores effectively, in this paper, blip （mercury intrusion porosimetry） is applied to measure the pores in sinter, and the fractal geometry was used to deal with the results, trying to analysis the sintering mechanism from a complete new point. The results of analysis show that the pores in sinter possess actually fractal structure, according to the calculation of the fractal dimension, the relationship of the strength and fractal dimension will be established.
