目的：检测铁铬合金菜刀遗留的金属颗粒成分，并建立可行的评价指标及方法。方法使用滤纸擦蹭菜刀制作金属遗留微小颗粒样本，应用扫描电镜-X射线能谱仪（scanning electron microscopy and ener-gy dispersive X-ray spectrometer，SEM-EDX）的GSR颗粒分析功能检测遗留金属颗粒成分，计算遗留金属颗粒中铁、铬相对含量比。结果铁铬合金菜刀遗留金属颗粒内所含铁、铬相对含量比，在大部分菜刀间差异有统计学意义（P<0.05）。结论使用GSR颗粒分析功能量化检测铁铬合金菜刀遗留金属颗粒内铁、铬相对含量比，为此类致伤工具的认定建立可行的评价方法。

Objective To establish a feasible evaluation index and method to identify composition of re-maining metal particles on ferrochrome kitchen knife. Methods The small samples of remaining metal particles were rubbed fromthe knives using filter paper. The composition of remaining metal particles was detected by scanning electron microscopy and energy dispersive X-ray spectrometer (SE m-EDX ) and GSR particle analysis function, using mathematical methods to calculate the ratio (relative amount) of Fe and Cr in remaining metal particles. Results The ratio (relative amount) of Fe and Cr of remain-ing metal particles had significant differences among most ferrochrome kitchen knives (P<0.05). Conclu-sion U sing GSR particle analysis function to quantitatively detect the ratio (relative amount) of Fe and Cr of remaining metal particles on ferrochrome kitchen knife, which can establish the feasible evaluation method to estimate such injury tool.
