Therefore , the policy analysis of green coverage ratio needs a special methodology with a holistic view to help decision maker to have confidence by building its accumulated construction of air purification system and simulating its long - term dynamic development trend 因此，需要一个具备整体观、建构空气净化系统结构、长期动态仿真等功能的方法? ， ?协助人们?解?覆?政策对于环境的实质生态效益，增进决策者对推动?覆?的信心。
Some successful examples include nickel - free metal alloys for watch and jewellery , advanced encapsulates with low moisture and tailored modulus for electronic packaging , textiles treated with nanostructured materials and water repellent apparels with high air permeability , and air purification system that removes odour and kills bacteria by photocatalytic nano - coating 成功例子包括：手表及珠宝专用的无镍合金；电子封装所需的低水分和特定模数的先进封装材料；经纳米结构材料处理的布料及透气度高的防水衣物；以及利用光催化纳米涂层技术，能够除臭杀菌的空气净化系统。
