摘　　要：为适应故障注入的自动化和实时性要求,针对试验人员需在试验开始前给出故障信息和编写试验方案,提出产品故障、元故障和故障模型概念,提取产品故障和元故障特征。在此基础上,采用IEEEStd1647TM-2006的"E"功能验证语言,描述故障特征、构建故障模型,并给出故障模式的描述方式。最后以某电子飞行显示系统为应用案例,案例表明,故障模型及其描述方法可有效地提高故障注入的自动化和实时性水平。To satisfy the automation and real-time requirements,fault information and experimental scheme need to be edited before the experiment starts. This paper proposed the concepts of product fault,atom fault and fault model,and extracted fault characteristics. On this basis,depicted fault characteristics by IEEE Std. 1647TM-2006 ＂ E＂ functional verification language, and constructed fault models. Then presented fault mode depiction method. Finally,addressed an electronic flight display system test as a case study,which verified the effectiveness of the fault models and depiction methods in improving the automatic level and real-time quality.
