弹头

For the reasons that knowing well to what extent the shots were damaged by the objects and whether the trails existing on the damaged shots still have the appraisal values or not, my classmates and I collected lead board, aluminium board, wooden board, rubber, bricks and so on, then we shot upon these fastened objects with the No. 64 pistols (7.62mm ) at 1 meter distance, at last we did the relative summary and research to the collected shots.

为了了解客体对射击弹头能造成何种程度的破坏以及被破坏的弹头痕迹是否仍具备检验价值，我们收集了铅板、铝板、木板、胶皮、砖块等客体，用64式7.62毫米手枪发射64式弹在1米内进行近距离打击，然后对收集到的射击弹头做了相关研究总结。
