Women prepare for South Pole trek 英國女性探險隊即將踏上遠涉南極之旅
文字稿 It's something we've all struggled with – how to get that last drop of ketchup out of the bottle. Here at MIT they've developed this clever new technology. The container has been specially engineered to enable the ketchup or any other sticky liquid to slip out easily. Scientists coat the inside with a rough surface. They then put a thin layer over it and they cover that with a liquid which fills in the troughs and forms a very slippery surface. This coating process could cut huge amounts of waste.
我們每個人都遇到過這樣的難題：怎么才能擠出瓶子里剩下的最后一小團番茄醬？麻省理工學院（MIT）的一組研究人員開發(fā)出了一種巧妙的新技術。該容器已經(jīng)過特殊的設計改造，能夠讓番茄醬等任何粘稠的液體輕而易舉地從瓶子里流出來。科學家們在瓶壁的內(nèi)側(cè)涂抹一層粗糙的表面，并在上方覆蓋一層輕薄的物質(zhì)，然后鋪上一種能夠注滿溝槽并形成非常順滑表面的液體。這個涂層的過程能大量減少浪費的情況。
The Ice Maiden team is heading out across a frozen Norwegian lake at the start of its final training exercise. In September, these soldiers will begin their historic journey hoping they'll succeed and inspire a generation of women. Home for the next few weeks and for the 80 days of the expedition will be a small tent. It will be the bedroom, living room and kitchen.
“冰娘子”探險隊準備開始她們出發(fā)前的最后一次訓練 - 橫穿位于挪威的一片結冰的湖泊。今年九月，這批戰(zhàn)士們將踏上一段歷史性的征途，她們希望能順利走完全程并借此經(jīng)歷激勵一代女性。在接下來的數(shù)周以及遠征的80天內(nèi)，她們會住在一頂充當臥室、起居室以及廚房的小帳篷里。
