摘 要:【目的】在提取到香烟物证的案件现场,对香烟内衬纸进行检验,可以获得嫌疑人的生活习惯、所在地域、经济状况等信息。【方法】选用紫外可见反射光谱法检测13种不同烟盒内衬纸、相近颜色烟盒内衬纸、同一烟盒内衬纸不同部位及同一品牌不同批次烟盒内衬纸,同时检测加热老化和自然光老化后的烟盒内衬纸。【结果】13种不同烟盒内衬纸、相近颜色烟盒内衬纸光谱图明显不同;同一烟盒内衬纸不同部位、同一品牌不同批次烟盒内衬纸光谱图无明显变化;加热老化后的内衬纸光谱图无明显变化,自然光老化50d后的烟盒内衬纸光谱图出现变化。【结论】通过紫外反射光谱法可以鉴别确定烟盒的种类。[Purpose] Cigarette physical evidence can often be extracted from the scene of various cases. Through the examination of cigarette physical evidence, we can obtain the suspect's living habits, geographical location, economic status, etc. [Methods] UV-visible reflectance spectroscopy can be used to study spectrograms of 13 different cigarette box lining paper, similar color of cigarette box lining paper, different parts of the same samples and different batches of the same brand. At the same time, we also determine cigarette box lining paper after thermal aging, natural light aging. [Results] The spectrum of 13 lining paper in different cigarette cases and similar color cigarette cases were significantly different;Different parts of the same sample and different batches of the same brand have no obvious changes in the spectrum;There was no obvious change in the lining paper spectrum after heating aging, but there was a change in the lining paper spectrum after 50 days of natural light aging. [Conclusion] UV-visible reflectance spectroscopy can be identified to determine the type of the cigarette box.
