用重１．０３ｇ，射速８００～８５０ｍ／ｓ和１３３～１４００ｍ／ｓ的钢珠致伤新鲜离体猪头的上、下颌骨，记录致伤瞬间上、下颌骨和其相对应的额骨、颞骨应变值，分析不同射速致伤时颅骨应变差异和弹着点距颅骨的距离与应变强度的关系，探讨颅骨应变在颌面部高速投射伤致颅脑损伤中的作用． The upper and lower jaws of freshly isolated pig heads were injured with steel balls weighing 1.03g, 800 ~ 850m / s and 133 ~ 1400m / s respectively, and the upper and lower jaws and their corresponding frontal and temporal bones were recorded Strain value, analyze the relationship between the strain difference of the skull and the distance from the skull to the strain intensity at different radii of injury, and discuss the role of skull strain in craniocerebral injury induced by high-speed projection on maxillofacial region.
