摘要
目的运用光学仪器研究内凹齿钥匙痕迹形态特征。方法制作内凹齿钥匙正常开锁和被钥匙机复制后的样本,用光学显微镜拍照固定痕迹特征。结果内凹齿钥匙开锁痕迹特征明显,且被钥匙机复制后能留下复制痕迹。结论通过检验内凹齿钥匙上的痕迹特征能确定钥匙是否被复制过。
Objective To analyze the marks on the concave surface key. Method Samples of manipulated keys and keys that used as guide in a duplication process are rnade. Marks and striations on the keys are photographed and analyzed by light microscopy. Result There are distinctive marks on concave keys when normally used and when used as guide keys. Conclusion The examination of a concave key can reveal distinctive marks whether the key has been used as a guide to create another key.
