London's new black cabs put to Arctic test 倫敦新黑色出租車送往北極測試
Pollution-fighting pigeons?英國科學(xué)家利用鴿子研究城市污染模式
文字稿
This is the brand new design for the iconic London black cab. But before they can put this through its paces in the cities, they have to try it out in one of the most hostile environments on Earth. It's got an electric engine, most of the time driving with zero emissions, although a small petrol motor charges the battery from time to time.
這是倫敦著名的黑色出租車的全新設(shè)計樣式。但在新車型被投入到各城市中大展身手之前，工作人員需要先把它送到地球上環(huán)境最嚴(yán)酷的地區(qū)之一試駕。新款黑色出租車配有電力引擎，且在大多數(shù)駕駛時間內(nèi)可實現(xiàn)零排放，但它仍裝有一臺時而需要為汽車電池充電的小型汽油發(fā)動機。
Can pigeons help us in the battle against air pollution? It sounds far-fetched but academics from Birmingham University are convinced they can. They're attaching sensors to the birds which, unlike drones, can fly without restrictions above busy urban centres. The information collected will help to model how pollution moves around cities and could be used by planners to help decide where to build hospitals or schools.
鴿子能幫我們對抗空氣污染嗎？這聽起來令人難以置信，但一組來自伯明翰大學(xué)的學(xué)者對此堅信不疑。他們給這些鳥綁上傳感器，和同樣安裝了傳感器的無人機不同的是，鴿子可以不受限制地在繁忙的城市上空翱翔。由這些鴿子收集到的信息能幫助科學(xué)家模擬污染物在城市移動的模式，城市規(guī)劃者也可以根據(jù)這些信息決定設(shè)立醫(yī)院或?qū)W校的地點。
