该文在不同的环境温度下对镍铬丝电引火头进行了瞬态脉冲无损检测 ,利用 Rosen-thal模型计算了电点火头温升参数。显著性检验表明 ,环境温度对温升无显著影响 ,在无损检测时可以忽略环境温度的影响
In this paper, transient pulse non-destructive testing of Nickel-Chromium wire ignition head was carried out under different ambient temperatures. The temperature rise parameters of the ignition head were calculated by Rosen-Thal model. Significance tests show that the ambient temperature has no significant effect on temperature rise, and can ignore the effects of ambient temperature in nondestructive testing
