摘要： A testing system for testing flatness of a surface of a workpiece includes a testing apparatus (10) and a processor (20). The testing apparatus includes a testing box (12) and a measuring apparatus (14). The testing box includes a plurality of holders (122); the holders define a datum plane. The measuring apparatus comprises a plurality of movable testing poles (142) extending out of the testing box and a plurality of gauges (141) configured for measuring distance of the testing poles retracting into the testing box. Ends (1421) of the testing poles away from the testing box are located at the datum plane and configured for supporting the surface of the workpiece thereon to allow the gauges measuring retracting distance of the testing poles under the pressure of the workpiece. The retracting distance of the testing poles is equal to distances between testing points on the surface of the workpieces and the datum plane. The processor is connected to the testing apparatus for receiving and processing testing data that are converted from the retracting distance of the testing poles measured by the gauges.

摘要： A system and method are presented that identify new, modified, unchanged, and deleted files in an incremental backup through a file list maintained on the backup destination. The FileList is a flat file in which file information about each file on a source node is stored sequentially into the file. During a subsequent incremental backup, the FileList is read sequentially from the backup destination and is used to generate a search tree. A hash value based on the file path is the key to the search tree, with the file's modified time and size being hashed together to form the value of the tree's key-value pair. Files are examined on the source and compared to the key-value pairs in the search tree. Status information in the search tree is modified to indicate discovered files. Unmodified status information identifies files that have been deleted since the previous backup.
