Existing literature on the relationship between bullet diameter and bullet defect diameter in the human calvarium is summarized and discussed. The hypothesis, derived from the literature, that bullet deformation influences bullet defect diameter was studied in a small controlled experiment. The mean defect size caused by non-deforming projectiles was found to be smaller than the mean defect size caused by deforming projectiles of equal original mass and size. The p value of the difference between the two means, measured in two different ways, was found to be 0.002 for both in a Mann-Whitney U test and was significant if the confidence level is set at 5%.
本文总结并讨论了现有关于人类颅骨中子弹直径与弹孔直径关系的文献。从文献中得出的关于子弹变形影响弹孔直径的假设，在一个小型对照实验中进行了研究。结果发现，由未变形子弹造成的平均弹孔尺寸小于由质量和尺寸相同的变形子弹造成的平均弹孔尺寸。在曼-惠特尼U检验中，用两种不同方法测量的这两个平均值之间差异的p值均为0.002，若将置信水平设定为5%，则该差异具有统计学意义。
