Voice 2: Synthetic Gecko is not only strong. It is clean too. People can buy other strong substances for fixing things. But these substances can damage surfaces. The new material does not. When the scientists remove it from a surface, it does not leave a mark.
聲音二：“人造壁虎”材料不僅強堅固。還很干凈。人們可以購買其他強力物質(zhì)來修理東西。但這些物質(zhì)會破壞表面。這種新材料則不會。科學家將新材料從表面移除時，不會留下痕跡。
Voice 1: The material is made using a process called photo-lithography. Scientists use this process for making silicon computer chips. It is a common technology. Photo-lithography uses light to create shapes in the plastic. The shapes look like the sticks, the stems, that support plants. But there are millions of them. They work in the same way as the setae on the feet of geckos. They produce the same Van Der Waals forces.
聲音1：這種材料用一種名為光刻的工藝制成。科學家用這種方法制造硅計算機芯片。這是一種常見的技術。光刻技術利用光學創(chuàng)造塑料的形狀。這些形狀看起來像支撐植物的樹枝和莖。但是數(shù)量有數(shù)百萬個。它們的原理與壁虎腳上的剛毛相同。它們會產(chǎn)生同樣的范德華力。
Voice 2: So far the team have produced several pieces of the material. Each piece measures one hundred millimetres in diameter. The development is still new. But Doctor Haq is hopeful. He believes that Synthetic Gecko will be quick and easy to make. He thinks that many people will find it useful. He believes the company will make a lot of money. But Doctor Haq wants to make one point. The material may be able to hold a car. It may be able to support an elephant. It may let us climb up walls without equipment. But it will be long time before humans can climb and move like geckos. They are the experts at speed and performance.
聲音2：到目前為止，這個團隊已制作出多塊材料。每塊材料直徑100毫米。這一研究成果還是新生事物。但哈克醫(yī)生對此充滿希望。他相信“人造壁虎”材料能迅速且容易地制造。他認為許多人會發(fā)現(xiàn)這種材料很有用。他相信相關公司會賺很多錢。但是哈克醫(yī)生想說明一點。這種材料也許能承受住汽車的重量。它也許能支撐一頭大象。它可以讓我們不使用裝備就能爬上高墻。但人類要像壁虎一樣攀爬和移動還需要很長時間。畢竟壁虎是速度和性能方面的專家。
