滴水消失型防伪技术是由清华大学和北京大学物理、化学系的专家科技人员在滴水过滤技术的基础上研制开发的一种新型防伪技术。它做为防伪标识是利用选择性的辐照和蚀刻,在标识的局部做成半透明的微孔,形成特定的图案。其防伪原理是:1.滴水消失型技术的制造需要尖端的中离子技术 Dripping disappear anti-counterfeiting technology by Tsinghua University and Peking University Department of Physics and Chemistry experts and technicians in the drip filtration technology based on the development of a new type of anti-counterfeiting technology. It is used as a security mark is the use of selective irradiation and etching, made in the logo of the local translucent micropores, the formation of a specific pattern. The anti-counterfeiting principle is: 1. Dripping disappear type of manufacturing technology requires sophisticated ion technology
