| 摘 要： | 目的研究内、外铣槽钥匙机械配制后痕迹的出现规律及其影响因素。方法利用传统的痕迹检验方法观察痕迹出现的位置、形态及分布规律。结果内、外铣槽钥匙机械配制后会留下不同于其原始加工痕迹和使用痕迹的增配痕迹，这种痕迹是否明显出现、出现的形态和位置受钥匙材质和结构、配匙机、配匙人员工作经验等因素的影响。结论当未发现内、外铣槽钥匙上有明显增配痕迹时，不能轻易做出钥匙未被增配的判断。

| Abstract: | Objective To study the characteristics of marks on duplicate milled groove keys. Methods Different milled groove keys were duplicated by different machine and people, and then the marks on duplicate key was observed under micro- scope. Results On the duplicate key, the added marks were found, which are different from manufacture marks and use marks on original key. The characteristics of marks were affected by key material, configuration, duplicating machine, the people who ma- nipulate the machine. Conclusion When the duplicated marks on a milled groove keys weren~ t been found obviously, it can~ t leap to a conclusion that the key is the original key. |
