Trajectory deflections of pistol bullets from four different firearms, fired through soft tissue simulants under two different incidence and exit angles were studied. The data from this study can be used in reconstructions of shooting incidents where human soft tissues (not bones) were perforated with pistol bullets and assumptions must be made about bullet deflection in order to correctly reconstruct trajectories. The results demonstrate that deflection was influenced by the length of the "wound channel" through the simulants. In short, deflection was small to virtually absent with 5 and 10cm channel lengths. With channel lengths of 15, 20 and 25cm, there was a clear increase in deflection and/or a more erratic deflection behaviour with most shots. The data also suggest an influence of the angle of incidence and/or exit on both the direction and the magnitude of the deflection.
研究了四种不同枪支发射的手枪子弹在两种不同入射角和出射角情况下穿过软组织模拟物时的弹道偏转情况。该研究的数据可用于重建手枪子弹穿透人体软组织（而非骨骼）的枪击事件，且为正确重建弹道，必须对子弹偏转情况进行假设。结果表明，偏转受穿过模拟物的“创道”长度影响。简而言之，创道长度为5厘米和10厘米时，偏转很小甚至几乎不存在。创道长度为15厘米、20厘米和25厘米时，大多数射击的偏转明显增加和/或偏转行为更加不稳定。数据还表明入射角和/或出射角对偏转的方向和大小均有影响。
