地铁安检

地铁安检

作为奥运会结束后北京地铁保留的一项措施，地铁安检已经被越来越多的乘客所接受。

请看《中国日报》的报道：
Subway security officers are considering rapid checks for small bags, which means such bags won’t have to go through X-ray machines. However, because of the huge passenger flow, passengers with small bags, such as waist packs, can actually escape security checks even now.

在上面的报道中，security check就是指“安检”，指的是通过X-ray machine（X光机）查看乘客的包内是否携带了prohibited/ forbidden items（违禁物品）。为方便安检人员进行hand check（手检），地铁内还专门配置了portable scanner（便携式扫描仪），liquid testing machines（液体检测仪）。安检制度实施以来，地铁内已多次查出inflammable and explosive materials（易燃易爆物品）。此前，地铁安检一直实行的是random check（抽检）制度。
