| 摘 要： | 目的为自动消色笔书写笔迹的显现识别提供最佳方法。方法通过观察不同种类的自动消色笔书写在不同纸张上,保存在不同环境下的笔迹的消色过程、消色时间,分析判断消色笔书写笔迹的基本特性。使用文检仪、静电压痕仪、不同浓度的氢氧化钠溶液显现消色笔迹,比较不同显现识别方法的特点及优劣。结果不同的显现方法各有优劣,使用氢氧化钠溶液显色效果的最佳浓度为1.0 mol。结论在自动消色笔书写笔迹的显现中,可以根据不同情况,选择合适的显现方法达到识别检验的目的。

| Abstract: | Objective To Provide the best method to visualige the auto-decoloring handuriting. Method The characteristics of the entries written with fading inks were summaviged by studying the fading process and fading time on different types of paper and in different environments. Video spectral comparator, static indentation instrument and sodium hydroxide solution of different concentrations were used to develop the fading process, and the effects of these methods were analyzed. Result The three methods had both advantages and disadvantages. The optimized concentration of sodium hydroxide solution was 1.0 moL/L. Conclusion Appropriate methods should be selected under different conditions to develop faded ink entries. |
