摘　　要：基于焦炭结构是影响焦炭质量的主要因素,综述了焦炭的气孔结构、光学显微组织及微晶结构表征的研究方法,指出其主要测定方法包括抽气法、液氮吸附法、压汞法、SEM、图像分析法、偏光显微镜、XRD、TEM、XPS等,分析了焦炭气孔结构对焦炭质量的影响,展望了研究焦炭微观结构与宏观性质之间关系的必要性。Coke structure is the main factor which affected the quality of coke. Research methods for coke pore structure, optical microstructure and microcrystalline structure were reviewed in this work. The determination methods mainly included： degassing method, liquid nitrogen adsorption method, mercury-injection method, scanning electron microscopy （SEM）, image analysis method, polarized light microscope, X-ray diffraction （XRD）, transmission electron microscopy （TEM）, X-ray photoelectron spectroscopy （XPS） and so on. The necessity of study on the relationship between the coke microstructure and macroscopic properties was prospected in this paper too.
