甲骨形態研究在甲骨綴合實踐中起著十分重要的作用。龜腹甲各個部位依靠齒縫咬合在一起,時光荏苒,龜版極易從齒縫處斷裂,形成龜縫片。右後甲龜縫片沿背面靠近甲橋的鉆鑿斷裂後,分為左右兩部分。原邊所在的窄窄的龜版受外力影響大多在腹股溝附近斷裂。基於上述兩條規律,筆者留心於右後甲殘片,發現新綴六例,內容涉及氣象、戰爭、卜王、卜旬等方面。

Understanding morphology of the oracle bones and turtle shells plays a significant role in the practice of oracle-bone refitting. Biologically, various parts of tortoise plastrons fused together along the jagged edges. However, plastrons would gradually fall apart along sutures. The author suggests that the right femoral and anal plastron usually breaks into the right and left parts because of the fracture caused by cracking holes near the bridge on the back. Impacted by this external force, the small, slim plate with the original edge will also break apart along the abdominal groove. Having observed these two cracking patterns, the author focuses particularly on remains of the right femoral and anal shell fragments. The author discovers six new cases of successful refitting listed below and suggests the new refitting cases facilitate the interpretation of records on climate, warfare, kingly affairs, divination, etc.
