Abstract: Various kinds of practical parameters are often calculated during radiographic testing; however, since computational formulas of some practical parameters are complicated due to so many input variables, the manual calculation workload is therefore heavy and is liable to mistake. Excel is the most widely-used computer software in data processing, and it enjoys advantages in many fields, such as processing and analyzing data, making electronic forms and graphs and so on. By using its functions of formula, function, intelligence recalculation, etc., the computational process of practical parameters can be designed and optimized, therefore the computation form will be established with features of convenient input, rapid calculating, accurate result, etc., which will greatly improve the work efficiency and management of testing personnel.
