【摘要】 提出了一种借助于PowerBuilder8 0的数据管道技术对Sybase数据库中表的结构及属性进行创建和修改的间接方法。从数据管道技术提出的必要性、数据管道技术的实现方法等方面进行了详细的论述,同时,对于利用数据管道技术在远程服务器的数据库间进行数据传输也给出了简要的叙述。实践证明,其在应用程序的开发特别是调试阶段,为数据库的创建提供了方便。更多还原

【Abstract】 A kind of parameter self-regulation fuzzy controller used in the temperature control system of furnace is introduced. The principle of the parameter self-regulation is presented and a fuzzy control algorithm is given.The work principles,the characteristics,and the compositions of software and hardware of the parameter self-regulation fuzzy controller with single-chip microcomputer are discussed. It shows by simulation that the temperature control system of electrically heating furnace is of more control accuracy and a good dynamic characteristic and a good property of robust.更多还原
