射线检测需要经常计算各类检测实用参数，因部分实用参数计算公式复杂、输入变量较多，存在手工计算工作量大、计算结果出错率高等问题。Excel是目前应用最广泛的微机数据处理软件，它具有强大的处理和分析数据、制作表格、创建图表等功能。利用Excel中的公式、函数和智能重算等功能，对实用参数的计算过程进行设计和优化，形成的计算表格具有输入方便、计算快速、结果准确等特点，能极大地提高检测人员的工作效率和管理能力。

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.
