本文利用田口玄一正交法，对某一机电工程检测案例的计划、筛选、抽样等环节影响客观结论可信性的问题进行了分析推导；并对抽样过程中存在的系统误差程度做出定量评测；同时，分别就以工作时长为代表的效率因素，以抽样概率和抽样误差为代表的准确度因素，通过数理统计，阐述其组成及综合平抑的方法，为评估机电工程检测结论的可靠性进行了有益探讨。
By using Taguchi method, some issues affecting the reliability of objective conclusions of electrical- mechanical engineering during its planning, choosing and sampling are analyzed. Also, the system error in the sampling process is quantitatively evaluated. Meanwhile, efficiency factors such as work time and accuracy factors such as sampling probability and sampling error are figured out to describe its composition and comprehensive stabilization methods. And beneficial discussion has been done in order to evaluate the reliability of electrical-mechanical engineering testing results.
