人民币作为“国家的名片”,采用了多种国际上最先进的防伪技术，是世界上防伪水平最高的货币之一。为了研究人民币的防伪技术特征在货币流通过程中的磨损情况，以钞票整洁度水平为依据，对2015年版第五套人民币100元纸币进行分级抽样检测。结果表明：背面软磁、安全线磁性、号码磁性等防伪技术特征与人民币磨损程度无关，荧光磁性防伪特征与人民币流通整洁度之间存在一定的数理意义上的相关性。

As the “business card of the country”, RMB adopts many of the most advanced currency anti-counterfeiting technologies in the world in the printing process, and is one of the currencies with the highest anti-counterfeiting security level in the world. Clean and tidy paper money is easy to associate with advanced banknote printing technology and strict currency circulation system. On the contrary, damaged and filthy banknotes will greatly reduce the image of the country's sovereign currency. In order to study the wear and tear of RMB anti-counterfeiting technical characteristics in the process of currency circulation, the fifth set of RMB 100 banknotes of 2015 edition were sampled and graded according to the cleanliness of banknotes. The results showed that the anti-counterfeiting technical characteristics such as soft magnetic on the back of banknotes, safety line magnetic and number magnetic will not be reduced in the circulation of RMB, and there is a certain correlation between the fluorescent anti-counterfeiting characteristics and the change of the cleanliness of RMB circulation.
