摘　　要：焦炭光学显微结构的研究包括焦炭光片的制作和偏光显微镜下显微结构的定量分析,选用P600,P1500,P3000号水磨砂纸,对焦样进行预磨,得到光滑、精细的光面,再经过干、湿抛光,得到表面光亮如镜、无划痕的焦光片;在显微镜下观察,光片无麻点和划痕,视域清晰,结构明显。Study of optical microscopic structure includes preparation of coke sample with polished section and quantitative analysis of optical microscopic structure by polarizing microscope. After pre-sanding with P600, P1500,P3000 sand paper, the coke surface became smooth and fine. By dry and wet polishing, the glassy surface was obtained.Observed by polarizing microscope, the field of vision was clear, and the microstructures of the surface without pit and scratch were distinguishable.
