6、圖案區(qū)將被著色，留下彩色圖案。若用無色液體（如水）去涂抹，圖案區(qū)將變得透明，達(dá)到圖案消失的效果。另外由于重離子微孔的分布是隨機(jī)的不可重復(fù)的，特別小的微孔在受到單能X射線照射時有著特殊弗朗和卡衍射效應(yīng)，據(jù)此可進(jìn)行圖象的自動識別 。 Since the pattern is formed by micro pores, so the pores are gas-penetrating and water-permeable. Painted with colored liquid (such as ink), the patterned area will be colored, leaving

7、a colored image. Smeared with colorless liquid (such as water), the patterned area will become transparent and die away. In addition, as the pore distribution is random and unrepeatable, extremely small micro pores have the special Fraunhoffer diffraction effect when radiated by mono-energetic X-ray
