This paper analyzed current technology of duplicated data detection,and designed a three-tier detection model for the process of backup & restore which achieved a balance between the accuracy and the cost of detection.

This article not only focuses on data cleaning methods to ensure data quality of the safety of marketed drugs,such as triage strategies and duplicate detection,but also compares the classical signal detection methods in practice,including the conformity of these methods.

Based on the testing data of the quality of sinter,the influences of chemical composition and mineral composition on metallurgical properties of the sinter are investigated.

When large testing data are managed with computer,all kinds of the data for quality control can be not only easily and quickly obtained by statistic method,so that those testing data are fully used,but also the dynamic state of quality and testing schedule can be mastered and known well at all times,so as to make a convenience for the dispatching mangement

Design and implementation of synthetical information platform on railway engineering inspection data;

Meanwhile,it calculates the quality test data,from which draws a conclusion on the factors that influence the quality of ram-compaction piles with composite bearing base and puts forward suggestions that can guarantee the piling quality from the perspective of design,building and test.

Questions and suggestions are put forward according to the test data of 81 products from 46 enterprises,which show enterprises need to improve production level and strengthen man-machine engineering design.
