采用很多措施来防止伪造,然而这些方法都是可以复制的,能否找到一种无法复制的标记方法呢?采用固体径迹技术,可以达到这个目的。这对于机密证件的制作、重值货币的印制、工艺美术品的保真以及名牌产品的信誉保护等,都具有重要意义。 1.原理 所谓固体径迹,就是带电粒子在电介质固体中产生的痕迹经化学蚀刻后在显微 There are many ways to prevent counterfeiting, but these methods are reproducible, and can you find a way to mark them that can not be duplicated? This is achieved using solid-tracking techniques. This is of great significance to the production of confidential documents, the printing of heavy value currency, the fidelity of arts and crafts and the reputation protection of famous brand products. 1. The principle of the so-called solid track, that is charged particles in the dielectric solid generated traces of chemical etching in the microscopic
