    摘要: A method is provided for determining and controlling feed water level in a steam generator of a nuclear power plant, whereby the water level sensor is calibrated in terms of the pressure drop across structural components in the feed water path. The water level differential pressure sensor is calibrated so that maximum water level is indicated as the level corresponding to the upper tap level plus the pressure drop across the foregoing structural components at maximum power plant power.

    摘要: Domain indexes (indexes created and maintained by user-defined indexing schemes) are managed on partitioned database objects that store data using a system-managed approach. Partition maintenance operations performed on the partitioned database objects cause corresponding partition maintenance operations to be performed on the domain indexes. Partition maintenance operations are performed on both the database objects and the indexes by a system-supplied partition manager. Changes in the partition maintenance operations or partitioning methods supplied by the database management system do not affect user-supplied code which is provided by the user-defined indexing scheme. User-supplied code is therefore partition operation-unaware.

    摘要: A method and apparatus of operating a display system for displaying data items stored in an associated database. The database stores a display function for each data item class to be also stored in the database therein. When the user selects a data item class, a data item of and a display function associated with the selected data item class are retrieved from the database. The data item is used as an argument of a display function call. The system displays an object using the display data and the data format returned as the result of the display function call. The system may store multiple representations of each data item such as, pictorial, textual and audio representations which may be selected under user control.
