A Dutch artist and designer has come up with a device he hopes will suck pollutants from Beijing's smog-cloaked skies, creating columns of clean air for the city's surgical-mask wearing residents. 一位荷兰艺术家兼设计师发明了一种装置，他希望借此装置能够为北京烟雾笼罩的天空清除污垢，为那些戴着口罩的北京市民创造新鲜的空气。 An electromagnetic field generated by copper coils will pull airborne particles in the smog to the ground where they can be easily cleaned. 通过铜线圈制造的电磁场可以将漂浮于烟尘中的颗粒物吸附到地面上，很轻易的被清理干净。 "It's like when you have a balloon which has static (electricity) and your hair goes toward it. Same with the smog," says artist Daan Roosegaarde. 荷兰艺术家戴恩·罗素格地说，“就好像如果你有一个带静电的气球，头发就会被气球吸附一样。烟尘也会被吸附。” |
