摘　　要：从生物力学角度研究人牙咬痕形态学变化的动态过程。以不同形态的牙和不同量的牙合力造成活体和死亡动物的咬痕 ,长时间动态追踪观察其变化过程 ,并测定相关形态参数 ,多元逐步回归分析咬痕形态与牙合力、时间、牙形态包括牙面积、牙宽度、牙厚度之间的关系 ,建立了咬痕形态学变化与多个力学、形态学因素的内在数学关系。This is a biomechanical research in the morphological changing process of human bitemarks on the skin of dogs. The human bitemarks were made on the live and dead dogs by different tooth and occlusal force. The changing process of the bitemarks were receorded for a long time and its related morphological parameters were measured. Then multiple stepwise regression analysis was made to disclose the relationship of the shape of the bitemarks to occlusal force,time,and tooth area,tooth width and thickness. The mathematic relationship of the morphological changing process of the bitemark with occlusal force,time and tooth shape was eslablished.
