摘　　要：对古代碳化稻谷进行了高分辨电子显微镜、X粉晶衍射和激光拉曼光谱研究。高分辨电子显微像表明它为芳层石墨。一级激光拉曼光谱D峰波数为1371.4-1386.4 cm-1,多大于1370 cm-1;O峰波数为1600.7-1610.4 cm-1。根据拉曼光谱D/D+O面积比计算碳化稻谷的La为5.4-14.1 nm,这与高分辨电子显微像观察结果相一致。Carbonated paddy has been studied through high resolution transmission electronic microscopy (HRTEM) ,X -ray powder diffraction and laser Raman spectroscopy.The carbonated paddy was fragrant layer graphite. The D - peak position of carbonated paddy is from 1371.4cm' to 1386.4 cm-1 ,and more higher than 1370 cm-1 .The O - peak position is from 1 600.7 cm-1 to 1 610.4 cm' .The estimated La on the basis of D/D + O area ratio is 5 .4nm - 14. 1nm of carbonated paddy which consisted with HRTEM.
