图6 AⅠ、BⅠ组各骨缝的最大主应变图示（右视图及前视图） Note： A. Pterygomaxillary suture. B. Zygomaticomaxillary suture. C. Zygomatic temporal suture. D. Zygomatic bone. E. Nasomaxillary suture. F. Nasofrontal suture. In scale label, positive value represents tensile stress, and negative value represents compressive stress. Based on the right and frontal views of the nasofrontal suture, which are represented as points and lines with relatively small values, no analysis was conducted on the nasofrontal suture in this area.
