两名苏格兰科学家发明了一种制造天文望远镜镜片的价廉物美的新方法。据认为这是伽利略发明天文望远镜以来一次重大革命,并可解决美国“星球大战”计划中的一些关键技术问题。格拉斯哥的Strachclyde大学的这两名科学家说,从此就可以摒弃笨重而又昂贵的玻璃镜片了。传统的曲形抛物线反射面是由无数块涂银或涂铝的玻璃组成,而现在却可由其反射性能与玻璃镜子相媲美的塑料片取而代之。 Two Scottish scientists invented a new, inexpensive, new method of making astronomical telescope lenses. It is believed that this is a major revolution since Galileo invented the astronomical telescope and could solve some key technical issues in the U.S. “Star Wars” plan. The two scientists at Strachclyde University in Glasgow said that since then it is possible to get rid of bulky and expensive glass lenses. The traditional curved parabolic reflector consists of countless silver-coated or aluminum-coated glasses, which are now replaced by plastic sheets whose reflectivity resembles that of glass mirrors.
