摘要： 目的 观察不同类型打击工具的垂直抛甩状血迹形态。 方法 选择常见的菜刀、匕首、方锤、铁管作为打击工具。用沾新鲜鸡血5 mL的工具自上而下进行垂直抛甩，对距离垂直墙壁30 cm处形成的血迹形态进行测量分析，通过对抛甩血迹的整体分布特征（跨度、宽度、密度）、起始血迹的形态特征（长度、宽度、接触角度）进行分析。 结果 匕首形成抛甩血迹的分布跨度最小（P<0.05）；在整体分布宽度上，菜刀最小（P<0.05）；在整体分布密度上，除菜刀与方锤之间差异无统计学意义，其他工具两两之间差异均有统计学意义（P<0.05）。方锤较其他三种工具在起始血迹点长度上最长（P<0.05）；菜刀与方锤、匕首与方锤在起始血迹点宽度上差异有统计学意义（P<0.05）。 结论 每一类型的打击工具所形成的垂直抛甩血迹形态具有一定的特征，可用于命案现场推断打击工具的类型。

Abstract: Objective To observe the characteristics of vertical cast-off bloodstain pattern by different hitting-tools. Methods The regular hitting tools, a kitchen knife, a dirk, a plane set-hammer and an iron pipe, were selected. At a distance of 30 cm away from the wall, the hitting tool with 5 mL fresh chicken blood made the cast-off bloodstain from top to bottom. Then the holistic distribution characteristics （length, width and density） of cast-off bloodstain and morphology characteristics （length, width and contact angle） of first single cast-off bloodstain were analyzed. Results The distribution length of cast-off bloodstain formed by dirk was minimum （P<0.05）. The distribution width of cast-off bloodstain formed by kitchen knife was minimum （P<0.05）. Except the pair of kitchen knife and plane set-hammer, the distribution density between each two tools had statistical differences （P<0.05）. The length of first single cast-off bloodstain formed by plane set-hammer was longest compared （P<0.05）. The width of first single cast-off bloodstain had statistical differences between kitchen knife and plane set-hammer, and between dirk and plane set-hammer （P<0.05）. Conclusion The type of hitting tool could be inferred by the specific characteristics of cast-off bloodstain pattern formed by every specific type of hitting tool in crime scene.
