回顾本世纪初,许多科学家都曾经预言,人类将在本世纪结束前飞往月球。但是,他们谁也未预见到一项更加令人惊异的成就:人们可以在家里观看登月人在月球上行走,他们没有预见到本世纪出现的给我们的生活带来最大变化的电视技术。前些时候,美国的有关咨询单位把一批最有想象力的技术专家集中在一起,询问他们今后十年内哪些技术将对实业界具有重大的意义。下面就是这些专家预言的最具实用前景的十大关键技术:
Looking back at the beginning of this century, many scientists have predicted that humans will fly to the moon by the end of this century. But none of them predicted a more amazing achievement: people could watch the moonwalker walking around the house at home, and they did not foresee the television technologies that have brought about the greatest changes in our lives this century. Some time ago, relevant advisory units in the United States brought together some of the most imaginative technical experts to ask them which technologies will be of great significance to the industry in the next ten years. The following are the top ten key technologies predicted by these experts:
