In recent years, many studies have been conducted in the field of firearm identification with the objective of providing an objective method of evaluating the comparison of cartridge cases. However, less attention has been paid to the objective evaluation of bullet comparisons. In this study, 1 000 registered Chinese Norinco QSZ-92 pistols were used, and a database of 2 996 bullets was constructed. Both the receiver operating characteristic (ROC) curve and the score-based likelihood ratio method were used to objectively evaluate the similarity scores derived by the Evofinder system. The results indicate that this system has excellent ability to discriminate between the selected pistols. This paper proposes an objective evaluation method, which serves as a response to the ongoing debates regarding the foundation of the discipline.
近年来，在枪支识别领域开展了许多研究，目的是提供一种客观的方法来评估弹壳的比对。然而，对于子弹比对的客观评估关注较少。在本研究中，使用了1000支已登记的中国北方工业公司QSZ - 92手枪，并构建了一个包含2996颗子弹的数据库。采用接收器操作特性（ROC）曲线和基于分数的似然比方法，对Evofinder系统得出的相似度分数进行客观评估。结果表明，该系统在区分所选手枪方面具有出色的能力。本文提出了一种客观评估方法，作为对该学科基础持续争论的回应。
