摘要
目的对不同厂家的猎枪弹丸进行区分和鉴别。方法使用功率补偿型差示扫描量热仪(DSC)对4种不同品牌的猎枪弹丸进行分析。结果可测得每种弹丸的DSC曲线和熔点温度Tm,熔融峰温Tmp,熔化焓ΔHm等热学参数。结论利用差示扫描量热法可以对不同品牌的猎枪弹丸进行鉴别,该方法为办案过程中遇到同号数不同品牌的猎枪弹丸鉴别提供了一种有效技术手段。
Slugs from four types shotgun cartridge were analyzed by using Differential Scanning Calorimetry. Thermal parameters such as DSC curve, melting temperature and heat flow were compared. The results show that slugs from different type of shotgun cartridge can be identified by the thermal parameters.
