对某一汽车感温塞的失效分析表明，热敏电阻的阻值大大下降，明显地超过技术标准值，这是一种新的失效模式。它是在恶劣环境下，由于缓慢相变产生一个没有热敏性的并联电阻造成的。 The failure analysis of a car’s temperature-sensing plug shows that the resistance of the thermistor drops significantly and obviously exceeds the technical standard value, which is a new failure mode. It is in harsh environments, due to the slow phase transition to produce a thermistorless parallel resistance caused.
