| 摘 要： | 目的观察二次溅落状血迹的形态特征,探讨其形成机理及与行为方式的关系。方法建立室内现场环境,用10mL血液,以单滴连续滴落或一次性倾倒方式,从10～160 cm高度以10 cm为间隔,制作二次溅落状血迹模型;用棍棒打击及撞击方式制作低位打击及头部撞击溅落血迹模型。观察各种血迹分布,并分析比较其形态差异。结果二次溅落状血迹和头部撞击溅落状血迹在垂直面上均形成倒三角形空白区域的分布形态,但前者分布面积较后者小;低位打击溅落在垂直面上的血迹无此特征,且打击飞溅血滴的飞行角度大于二次溅落血迹。结论利用二次溅落状血迹的形态特征,对于鉴别低位溅血、分析行为方式、证实相关证词具有重要价值。

| Abstract: | Objective To observe the morphological characters of secondary spatter bloodstain and explore behavior-related mechanism.Methods Secondary spatter bloodstain pattern was created by successive free-falling blood drops,or one splash from 10 to 160cm at every 10cm height in each experiment using 10ml of blood sampled from human cadaver under room circumstance.Impact spatter bloodstains were mimicly produced by impact on the object covered with artificial hairs soaked with human blood or man-made head impact on... |
