原文标题： San Francisco Adds Pee-Repellent Paint to Buildings旧金山在建筑物中添加防尿涂料 原文： In an effort to prevent people from urinating on walls after a night out, San Francisco is trialling a urine repellent paint that forces the urine to “bounce back” onto the person.为了防止人们在晚上外出后在墙上小便，旧金山正在试验一种驱尿涂料，可以迫使尿液“反弹”到人身上。 The idea was inspired after the paint was used in a problematic area of Hamburg where tourists would urinate on walls outside of nightclubs and bars. 这个想法是在汉堡的一个有问题的地区使用油漆后得到灵感的，游客们会在夜总会和酒吧外的墙上小便。 The paint is called ‘Ever-Dry’ and it was designed to create a barrier of air in front of the surface, completely repelling any liquid. The idea is that if you pee on the wall, your pee will then bounce back onto you. 这种涂料被称为“Ever-Dry”，它的设计目的是在表面前形成一层空气屏障，完全排斥任何液体。这个想法是，如果你在墙上撒尿，你的小便就会反弹到你身上。 San Francisco, located in northern California, has now used the paint on nine different walls across the city where a combination of nightlife and homelessness has created a problem with people urinating on the streets. There have even been an influx of requests from local residents, asking if they can have walls or alleyways near their homes painted too. 位于加利福尼亚州北部的旧金山现在已经在城市的九个不同的墙壁上使用了这种油漆，夜生活和无家可归的结合造成了人们在街上小便的问题。当地居民甚至纷纷提出要求，询问他们是否也可以在家附近粉刷墙壁或小巷。 The city says the cost of using the paint and hanging up signs, advising people to “Hold it!” and to “seek relief in an appropriate place” is much less than paying for street cleaners to constantly clean problem urine areas. 该市表示使用油漆和悬挂标志的成本，并建议人们“坚持下去！” 并且“在适当的地方寻求救济”比支付街道清洁工不断清洁问题尿液区域要少得多。
