摘要
文中利用超声在传播过程中声通量守恒原理解决弹体底隙的检测技术问题。通过分析弹体钢壳中的超声特征获得弹体内锥面和药柱的粘接状态,从而测得弹体内锥面是否存在底隙。
Ultrasonic quatity eternity in the process of spreading is used to detect air clink in the cone.Whether there are air clinks in the inner cone is by analyzing ultrasionic characteristics in the cone steel shell to acquire cohesive states between the inner cone and the gunpowder pillar.
