摘要:为建立纸张物证快速、简便、无损的鉴别方法，利用Docubox Digital文检仪配置的“LUMI(蓝光) = 红外激发光”对A4静电复印纸样品的种类鉴别进行了研究，考查了热老化、紫外光老化和自然光老化对测定结果的影响。结果表明，在相同条件下，纸张样品的荧光现象不同，可对不同厂家、不同品牌和不同批次的静电复印纸进行鉴别和区分。该方法简便、快速、不损坏检材，为纸张相同性的比对和同一认定提供了一种简单、实用的检验方法。

Abstract:In order to develop fast, simply and nondestructive identification methods of papers, the kind identification of copy papers and the impact of thermal aging, ultraviolet aging and natural light aging on the results were studied by using LUMI（blue light）of Docubox Digital Video Spectral Comparator (VSC). According to the fluorescent phenomenon, the papers from different manufacturer, brands and batches could be distinguished and classified. This was a new, fast, sensitive and nondestructive identification method of copy paper, and provided a simple and practical testing method for comparison and identification.
