目的 研究运用文检仪显现同种同色掩盖字迹的显出条件.方法 以黑色签字笔为例,依据不同型号笔的油墨在不同光源下的荧光性质和红外吸收能力的差异,利用文检仪进行分析检验.结果 只有在一定条件下被掩盖字迹才能被显出.结论 在LUMI=IR红外荧光(兰光)下,只能显现激发荧光的油墨掩盖不能激发荧光的油墨的字迹和激发荧光能力弱的油墨掩盖激发荧光能力强的油墨的字迹;在红外吸收光和365nm长波紫外表面光下,只能显现颜色浅的油墨掩盖颜色深的油墨的字迹.
目的 研究運用文檢儀顯現同種同色掩蓋字跡的顯齣條件.方法 以黑色籤字筆為例,依據不同型號筆的油墨在不同光源下的熒光性質和紅外吸收能力的差異,利用文檢儀進行分析檢驗.結果 隻有在一定條件下被掩蓋字跡纔能被顯齣.結論 在LUMI=IR紅外熒光(蘭光)下,隻能顯現激髮熒光的油墨掩蓋不能激髮熒光的油墨的字跡和激髮熒光能力弱的油墨掩蓋激髮熒光能力彊的油墨的字跡;在紅外吸收光和365nm長波紫外錶麵光下,隻能顯現顏色淺的油墨掩蓋顏色深的油墨的字跡.

Objective To study the visualizing conditions of the obliterated writing covered by the same class and color inks us-ing a video spectral comparator. Methods Based on the differences of the fluorescent and infrared absorption characters of dif-ferent gel pens, visualizing conditions were tested by a video spectral comparator. Results Under certain conditions, some oblit-erated writing could be revealed. Conclusion Under the condition of LUMI = IR infrared fluorescence (blue light), only the un-excited fluorescence writing covered by the excited fluorescence ink, and the excited fluorescence writing covered by the stronger excited fluorescence inks, could be revealed. Under the condition of IR infrared absorb lighting and UV365nm long-wave ultraviolet lighting, only the light color writing covered by the dark inks could be revealed.
