解决根据皮肤创口推断刺器宽度的问题。实验在自愿捐献的12具男性尸体的胸部，用不同宽度和厚度的双刃匕首致创221个。应用法医学、解剖学及数理统计的理论和技术对创口形成机理、影响因素及其与刺器宽度的相关关系进行分析，得出了以下结论：刺器厚度与创口长度无明显相关，刺器宽度与创口长相关，创口回缩程度与创口方向及刺器宽度相关。并建立了两个最优回归方程，提出了一个根据皮肤双刃利器创口推断刺器宽度的方法。
Solve the problem of inferring the width of a thorn according to the skin wound. Experiments were conducted on the chest of 12 male bodies voluntarily donated with 221 double-edged daggers of varying width and thickness. Based on the theories and techniques of forensic science, anatomy and mathematical statistics, the formation mechanism of the wound, the influencing factors and the correlation between the wound healing and the width of the thoracic spine were analyzed. The conclusions were drawn as follows: There was no significant correlation between the throat thickness and wound length, In association with the wound length, the extent of wound retraction is related to the direction of the wound and the width of the suture. And established two optimal regression equations, put forward a method based on skin double-edged weapon wound inferring the width of the device.
