超高速武器对犬的致伤效应及其量效关系研究

目的 研究超高速武器对生物的杀伤特点以及致伤能量和伤情之间的关系,为其防治提供实验依据。方法 采用雄性华南犬12只,通过某型爆炸枪分别以15360J、12643J和8144J能量的超高速弹丸致伤动物,并用常规武器以843J能量的钢珠作致伤对照,观察动物局部伤情特点和全身主要脏器改变。结果 超高速武器致伤后肢体大多完全离断,损伤情况与爆炸伤类似,常规钢珠致伤后的伤情明显轻于超高速武器致伤;在超高速情况下,损伤程度与致伤能量无明显联系。结论 超高速武器对生物的杀伤力大、局部毁损严重;破片的质量、动量对杀伤力的影响明显大于速度和碰击能量,质量、动量越大,杀伤力越强。

Study of wounding effects and its relationship with energy of super high velocity weapon on dogs

Objective To study the wounding characteristics of super high velocity weapon and the relationship between the wounding effects and energy. Methods Nine Hunan male dogs were wounded by super high velocity aluminium bullet shot by the explosive gun with energies of 15 360J. 12 643J and 8 144J respectively while other three dogs were wounded by steel ball with energy of 843J, then the injured degree of local tissues and the pathological changes of main organs were observed. Results The limbs of dogs wounded by super high velocity weapon were mostly broken off and the injured degree didn't have notable relationship with wounding energy. The wounding characteristics of super high velocity weapon were similar to those of explosive wounds, and much more severe than those of steel ball. Conclusion Super high velocity weapon may cause severe injury to dogs. The execution of super high velocity weapon was much related to mass and momentum than velocity and energy of the bullet, and the more the mass and momentum is, the greater the execution is.
