摘　　要：借助氩离子抛光技术对煤表面进行抛光,通过扫描电镜可以清晰观察真实的孔隙形貌结构,对判断孔隙类型有重要帮助。该文对阳极电压、抛光时间、离子束入射角、样品台转速等条件进行研究,利用扫描电镜对抛光后的表面进行观察,比较不同条件下的抛光效果,找到适合煤抛光的条件参数。Porous structure characteristics of coal were observed by using scanning electron microscope observation and Ar ion- milling techniques. This analysis method showed macroscopic structure and ultrastructure of coal clearly. The anode voltage,polishing time and ion beam incident angle,etc.,were studied. The best determining condition and parameter were found.
