A similar transformation has overtaken plastics. High-strength polymers now form bridges, ice-skating rinks and helicopter rotors. And one new plastic that generates electricity when vibrated or pushed is used in electric guitars, touch sensors for robot hands and karate jackets that automatically record each punch and chop. Even plastic litter, which once threatened to permanently blot the landscape, has proved amenable to molecular tinkering. Several manufacturers now make biodegradable forms; some plastic six-pack rings for example, gradually decompose when exposed to sunlight. Researchers are developing ways to make plastics as recyclable as metal or glass. Besides, composites – plastic reinforced with fibers of graphite or other compounds – made the round-the-world flight of the voyager possible and have even been proved in combat:a helmet saved an infantryman’s life by deflecting two bullets in the Grenada invasion. Some advanced materials are old standard with a new twist. The newest fiberoptic cable that carry telephone calls cross-country are made of glass so transparent that a piece of 100 miles thick is clearer than a standard window pane. But new materials have no impact until they are made into products. And that transition could prove difficult, for switching requires lengthy research and investment. It can be said a firmer handle on how to move to commercialization will determine the success or failure of a country in the near future.能幫忙翻譯紅色部分嗎?? google & yahoo翻譯 我無法信任....

    在入侵格瑞那達戰役中,頭盔成功地擋住兩顆子彈而拯救了一個步兵的性命。有些先進的材料採用原來材質的標準但改採新的纏繞方式。最新用來傳輸跨國電信訊號的光纖纜線用特殊玻璃來製作,這種玻璃就算有一百哩長度,仍比窗戶用的玻璃透光度要好。但是當新材料備用來製作成商品時,問題就來了!轉變需要長時間研究與投資,而且並不容易達成。如何穩定的控管將之商業化將決定一個國家未來的成敗。
