国际STH信息检索系统简介随着通讯卫星、数据传输等高科技领域的飞速发展,继美国Dialog、Orbit等计算机检索系统之后,国际科学技术信息网络系统(STN International)于1983年成立。国际STH系统打破独国推出检索系统的先例,率先建立了三国(美国、德国、日本)合作建网,各自在本国设立自己的主机系统提供检索服务,三大主机系统通过卫星联网。十几年后的今天,该系统的检索功能、软件、数据库已趋完美,尤其是传输速度由64kBIT/s发展成1995年的1.9MBIT/s和1997年的6MBIT/s。
Introduction of International STH Information Retrieval System With the rapid development of high-tech fields such as communication satellites and data transmission, STN International was established in 1983 following the computerized retrieval system such as the U.S. Dialog and Orbit. The international STH system broke the precedent of the exclusive country’s launch of the search system and took the lead in establishing the cooperation network between the three countries (the United States, Germany and Japan), setting up their own host systems in their respective countries to provide search services and networking the three host systems through satellite networks. More than a decade later, the search function, software and database of the system have been perfected. In particular, the transmission speed has increased from 64 kBit / s to 1.9 MBIT / s in 1995 and 6 MBIT / s in 1997.
