                              1.射击残留物化学成分。

                              制式枪所应用的子弹,其中的火药为无烟火药,这种火药主要由硝化甘油和硝化棉等两种成分,除此之外,还添加了一定量的稳定剂、氧化剂和成型剂等。而在现场中,存在的射击残留物包括没有充分燃烧的火药颗粒,这些颗粒中会包含着火药配方中的大部分成分。而底火残留物中,主要包括起爆药、氧化剂以及燃烧剂,这些物质具有很高的敏感度,其主要成分包括S、Cl、K、Hg、Sb、Pb、Ba等元素。另外,射击残留物中也包含Cu、Zn、Fe、Pb元素,这些元素主要来自枪体、弹头以及底火封装材料等部分,这些材料比较微量,另外还包括Sn元素,其主要来自子弹底火中击发药表层锡箔盖片。

                              2.射击残留物的分布。
