摘　　要：本文通过参阅沥青中间相炭微球（MCMB）制备高密高强炭／石墨材料方面的国内外相关文献，比较全面地概述了本领域的研究现状与进展，重点阐述了原料种类、原料改性方法、制备工艺等因素对高密高强炭／石墨材料结构和性能的影响。对石墨材料中缺陷的形成机理进行了初步分析，在此基础上指出了目前研究工作的不足及解决的途径。论文凝练的四项主要研究进展，对于开发以MCMB为原料的高密高强炭／石墨材料具有一定的指导作用。according to careful reference to the related domestic and foreign literatures about preparation of high-density and high- strength carbon/graphite materials from pitch-derived mcmb（mesophase microcbead） in recent years, this review comprehensively presented the research status and development in this field. It particularly focused on the influence of types of raw materials, methods of modifying MCMB and fabrication process on the structure and performances of carbon/graphite materials. Additionally the forming mechanism of defects in high-density and high-strength carbon/graphite materials was preliminarily analyzed. On the base of the related above, the insufficient aspects in current researches and the approaches of dealing with relative problemes were put forward. The four items of research development summarized in this paper will provide certain guidance for developing high-density and high- strength carbon/graphite materials from pitch-derived MCMB.
