使用国产12号、16号商品猎枪及相应霰弹,以不同距离射击实验靶纸,研究弹杯损伤变化与射击距离之间的关系。结果表明,射击距离在30cm以内弹杯损伤不明显(P>0.05),30cm～70cm其损伤直径随射击距离增大而明显增加(P<0.001),呈显著正相关性,70cm～3m弹杯翻转与射入口重合,3m以外弹杯逐渐偏离中心弹道而无实际意义。
The use of domestic 12, 16 commodity shotgun and the corresponding shotgun, shooting experimental target paper at different distances to study the relationship between the damage changes of shooting cups and shooting range. The results showed that there was no significant difference between the two groups (P> 0.05). There was a significant positive correlation between the damage diameter and the firing distance (P <0.001) at 30cm ~ 70cm. The 70cm ~ 3m cups Flip and injection port overlap, 3m outside the gradual deviation from the center of the ballistic cylinder and no practical significance.
