摘　　要：目的基于安全线的形成方式,对假币常用的内置安全线防伪纸张进行分类并对其形态特征展开分析,为假币的串并及溯源提供一种新的技术手段。方法通过VSC6000文检仪观察、电镜及能谱分析相结合的形式,基于内置安全线防伪纸张中安全线的形成方式对其进行分类,并分析其形态特征。结果基于形成方式可将内置安全线分为三类,分别是复合式安全线、内凹式安全线、外凸式安全线。结论可通过安全线形态特征将内置安全线防伪纸张分类,从而判断假币所用纸张的来源,为假币的串并、溯源及精准打击发挥重要作用。Objective To distinguish the papers embedded of security thread with which to have the formation method based so that the papers commonly used for counterfeit banknotes were to classify through analysis of the thread’s morphological characteristics,with purpose to provide a new technical means for counterfeit banknotes to have them concatenated and traced into source.Methods The papers of embedding security thread were observed and analyzed with VSC6000 comparator,electronic microscope and energy dispersive spectrometer(EDS),successfully having their embedding security threads delved and known into the morphological features.Consequently,the papers were to classify on the basis of characteristic formation of the security threads.Results The security threads of the tested papers are of three types:composite,concave and convex.Conclusion The papers used for counterfeit banknotes could be classified and determined of their source from the morphological features of those relevant embedded security threads,hence could play a crucial role in concatenating cases,tracing sources and precisely attacking crimes of counterfeit banknote.
