化学数据库的应用已成为当前化学研究中的一种必要手段。近二十年来国际上化学数据库的研究进展很快,并在化学领域中发挥了越来越大的作用。化学数据库虽然在我国的起点晚于其它国家10—15年,但科学数据库及其系统的研究开发已列入国家计划并在积极进行。本文将对近年来化学数据库的特点及应用加以论述,同时也提出当前国际与国内的发展趋势。 The application of chemical database has become a necessary means in the current chemical research. In recent twenty years, the research on international chemical databases has progressed rapidly and has played an increasingly important role in the field of chemistry. Although the starting point of chemical databases in our country is 10-15 years later than other countries, the research and development of scientific databases and their systems have been included in the national plans and are being actively carried out. This article will discuss the characteristics and applications of chemical databases in recent years, and also present the current international and domestic trends.
