【摘要】 物性数据库是进行化工计算的基础,网络工程物性数据库一方面给用户提供了一种方便快捷的查询途径,另一方面也给化工网络仿真协作实验提供了后台数据。根据三层B/S结构,采用Java语言和Access数据库系统,设计了基于Web的工程物性数据库查询系统的实现框架、具体的体系结构及技术方案,实现了常见的化学物质的26种工程物性的查询。用户可以通过网络查询各种物质的物性数据,化工网络仿真实验也能通过这一网络数据库实时的读取数据。更多还原

【Abstract】 Physical properties were very important for chemical engineering calculation. A good way to retrieve physical properties was provided , and fundamental properties were provided to network chemical engineering experiment simulation by Web - based engineering physical properties database, which was designed with B/S 3 - tier model, Java language and Access. Physical properties of some matters could be queried through Internet. Data from the database can be transferred to experiment simulation system.更多还原
