摘要
本文对气囊反射器和刚性波动反射器的设计计算进行了探讨,论述了反射器和冲击器的匹配关系,以及如何确定反射器安装位置.
The designing and calculation of hole bottom reflectors, both of the air-chamber type and the rigid pulsate type, are dealt with in this paper, Problems about how to ma' e a well match of a reflector and a percussive tool, and how to determine the position for mounting a reflcctor are also discussed.
