自然环境腐蚀数据库结构与功能设计

DESIGNS OF DATABASE STRUCTURE AND FUNCTION FOR NATURE ENVIRONMENT CORROSION

介绍材料自然环境腐蚀数据库的特点、结构设计和主要功能．该库将收集、整理并贮存黑色金属、有色金属、混凝土、合成材料、保护涂层、电缆和光缆６大类常用材料在全国不同类型自然环境（大气、海水、土壤）区域的腐蚀数据，以及相关的资料和信息．它可提供数据管理、数据查询与检索、数据处理、数据库维护及输出报表、图形和文字信息等功能．

The designing ideas, the structure and the function for a corrosion database system for natural environmental corrosion have been introduced. In this database system, 5 000 000 of corrosion data from various regions all over the country are collected, arranged and stored, including 6 general classes of materials, i.e., ferrous metals, non ferrous metals, synthetic materials, protective coatings, concretes, electric cables and optical cables etc. as well as related materials. The system provides the functions of the data management, the data consultation and retrieval, the data processing, the database safeguarding, the data reporting and printing etc.
