摘要:

介绍了一个固体火箭发动机试验中的关联性试验故障错判案例，分析了由于验证方法不当引起错判的原因，并提出了在试验故障分析时要把验证方法写入故障图、对验证方法也要验证、对验证方法应根据重要性、价格等因素分别进行重点分析的故障分析观点。

Abstract:

By introducting one case of interact of solid rocket engine ground test,the reason for incorrect analysis due to incorrect verification method was analyzed,and the viewpoint was proposed that in test fault analysis,verification method must be written into fault chart,verification method itself must be verified,and verification method must be focally analyzed as per factors of importance,price,etc
