早炸和瞎火是电子引信研制中经常遇到的问题,二者表现形式虽然不同,但其产生的原因却往往是互相关联的。例如,弹道上突然出现的噪音可能引起早炸,但整个弹道上持续的大噪音则有可能造成瞎火。因此本文将二者归并为引信的非正常作用,一起进行讨论。实践表明引信非正常作用的原因是多方面的,其中目前已经被普遍认识的是引信内部的电源噪音、振动噪音、元器件和工艺上的缺陷。除此之外,也还有一些目前尚未搞清的因 Early frying and blind fire are frequently encountered problems in the development of electronic fuze. Although the two manifestations are different, the causes are often interrelated. For example, sudden explosions in the trajectory may cause early explosions, but continued loud noise throughout the trajectory may cause blind fire. Therefore, this article will both be merged into a fuze for the non-normal role, to be discussed together. Practice shows that there are many reasons for the abnormal function of the fuze. Among them, the power supply noise, vibration noise, components and process defects in the fuze have been generally recognized. In addition, there are some reasons that have not yet been clarified
