| 摘 要： | 该文介绍了化学化工等相关学科领域内常用的四个经典而重要的网络数据事实型数据库：Web of Science的化学子库、SciFinder、Reaxys、SpringerMaterials。分别对它们进行了数据来源、历史发展、收录范围等方面的简要介绍，并结合相同的检索实例：有机物蒽和无机物硫酸，使用了化合物分子式检索、化学结构检索等具有化学特点的检索方式，比较和分析了这4个数据库在检索途径以及所提供实验数据事实的数量、质量、种类等方面的共性和各自特点，并对该类型数据库的发展趋势作出归纳和预测。指出研究者应根据实际的实验需求，选取适宜的1个或多个数据库进行实验数据的查检和选用。

| Abstract: | The brief introductions of four classical and important web-based numeric databases： ISI Chemistry, SciFinder, Reaxys and SpringerMaterials, which are mostly used in chemistry, chemical engineering and materials science fields, have been given in this paper. Then two substances：organic anthracene and inorganic sulfuric acid, as the same two examples in contrast retrials. Thus the general and specific characters of these four databases on their numeric data, search methods and other aspects had been analyzed and compared. In addition, the development feature and trends of chemical numeric databases had been described and predicted. |
