人们已明确地认识到,技术知识已成为决定生产力、竞争力、经济成就的关键因素.现在一些高度工业化国家,不单输出有形的产品,而且还输出工业技术、专业知识、管理技术——知识成了无形的产品.目前全世界每年发表的科技文献已达五百万篇左右,基本是十到十五年翻一番,要想在浩如烟海的情报海洋里查找一份有实用价值的科技文献,如果没有科学的检索手段、那谈何容易.由于情报不灵,或检索手段不当而致使科研项目重复造成的浪费是惊人的,苏联就高达十到十九亿卢布,而美国也高达十到十三亿美元.例如美国六一年到六七年搞了一个阿波罗载人登月飞行计划,一共发射十七艘飞船,后七艘为载人登月飞行,只有六般发射成功.时间长,花钱多,而且还有失败,其重要原因之一就是情报检索失当.比如美科学家在对阿波罗飞船的燃料箱进行压力试验时,发现甲醇会引起钛
It has become clear that technological know-how has become a key determinant of productivity, competitiveness and economic success, and some highly industrialized countries now export not only tangible products but also industrial technologies, know-how and management know-how Invisible products.At present, there are about 5 million scientific and technical literatures published each year in the world, which basically doubled from 10 to 15 years. If we want to find a scientific and technical document of practical value in the vast sea of intelligence, Without scientific means of retrieval, that was easier said than done. The wasted duplication of research projects due to ineffective intelligence or improper retrieval means that the Soviet Union is as high as 10-19 billion rubles, while the United States is as high as 10-1.3 billion For example, the United States engaged in a plan to carry the Apollo manned lunar fleet between June 1 and June 6, in which a total of 17 spacecraft were launched and the last seven were manned lunches, with only six successful launches. More money, but also failed, one of the important reasons is the failure of intelligence retrieval.For example, scientists in the United States Apollo spacecraft fuel tank pressure test, found that methanol Will cause titanium
