陶寺文化中期ⅡM26出土1件骨耜,根据骨耜的出土状况,墓主可能为农官的背景,判断骨耜应具有农业礼器功能。据电子显微镜观察结果,骨耜上的刻痕是人为契刻。将ⅡM26骨耜的刻文字形与甲骨文“辰”字进行对比,并结合与农业或农事职官相关的背景,可认为该骨耜上的刻文可能为最初的汉字“辰”字。 According to the unearthed condition of the tibetan bone, the tomb owner may be the background of the agricultural officer, and the judgment of the bone trowel should have the function of agricultural ceremonial earthenware. According to the results of electron microscopy, the nicks on the bones are man-made. By contrasting the engraved glyphs of IIM26 bone with the inscriptions of “Chen” and the background related to agricultural or farming officials, the engraving on the bone can be considered as the initial Chinese character “Chen” word.
