摘要
应用数字超声检测仪研究了JOB -90 0 3和JO -915 9两种高聚物粘结炸药的声学特性 ,确定了超声检测频率、密度、厚度与炸药的超声特性参数的关系 ,讨论了炸药内部质量特别是裂纹和疏松对炸药声学特性的影响。
Acoustic characteristics of two kinds of polymer bonded explosives(PBXs), JOB-9003 and JO-9159, were studied with digital ultrasonic flaw detector. The relationships between ultrasonic frequency and ultrasonic characteristic parameters of explosive, between density of explosives and ultrasonic velocity and gain coefficient, between thickness of explosives and ultrasonic gain were obtained.
