The interpretation of bloodstain patterns at crime scenes has received increased attention in recent years. Important to an understanding of this is knowledge of the fundamentals of blood droplet formation and impact dynamics. A review of the literature reveals that a considerable amount of work has been done with aqueous drop dynamics. Workers in the forensic science area seem to have been unaware of this. In addition, some of the most important and comprehensive early work with blood droplet dynamics seems to have been forgotten. It is not cited in more recent publications dealing with bloodstain pattern interpretation. This literature is reviewed and discussed as well. The present study presents results of experiments with blood droplet dynamics and high-speed photographs of blood droplet impacts on stationary target surfaces. Some longstanding misconceptions of importance to forensic scientists engaged in crime scene reconstruction are discussed.
近年来，犯罪现场血迹形态的解读受到了更多关注。了解这一点的关键在于掌握血滴形成和撞击动力学的基本原理。文献综述表明，在水滴动力学方面已经开展了大量工作。然而，法医学领域的工作者似乎并未意识到这一点。此外，一些关于血滴动力学的最重要且全面的早期研究似乎已被遗忘。在近期有关血迹形态解读的出版物中并未被引用。本文也对该文献进行了综述和讨论。本研究展示了血滴动力学实验结果以及血滴撞击静止目标表面的高速摄影照片。文中还讨论了一些对从事犯罪现场重建的法医科学家而言长期存在的误解。
