A metal material Elongation Uncertainty of Measurement Results

Data. This efficient, safe, easy to query the data and print processing. Used inside the VB ADODC control and database to connect, with a record of DataGrid controls the display of the grid. (5) interface control module The module is mainly used to dynamically display changes each parameter, numbers and curves show the coexistence of dynamic graphics, real-time displays and historical curve curve similar to control configuration software are used in the data curve approach, the interface, clear and concise, visual effect is good. This method is worth learning from. (6) There are many other modules of the system auxiliary modules,[link widoczny dla zalogowanych], such as statements of the historical curve and the printing module, the standard Windows format, with the help of the module, and the operation of the system may be used as a magnifying glass tool module (for local amplification curve), calculators. 4. Conclusion The system is oil production for the problems encountered in the process,[link widoczny dla zalogowanych], improve the degree of automation and development field. It solves the logging process, high input, high-risk problems, improve efficiency of oil and gas field development. After the success of the system developed, the initial test in JiI East gas mining test result is good, then, through Xinjiang test Taxinan used in actual production, and achieved very good results. Therefore, the promotion of this system has a higher value. References [1] GreyPerry: TeachyourselfVisualBasic5in24hourySmsPublishing [21 have Meng Xiong, Wu Haihua.

Conclusion The above analysis has been based on metal elongation A = 34% ± 3%, the report of the expanded uncertainty of the coverage factor k: 2.08,[link widoczny dla zalogowanych], confidence probability P = 95%. ● ■
