摘要
根据某种有机玻璃中超声纵波声速随温度变化的情况 ,分析了斜探头 k值、扩散角随温度的变化规律 ,分别导出了它们各自的数学表示式 ,并讨论了探伤温度对探伤灵敏度和缺陷定量。
It is analyzed the variation rule on K value, diffuse angle of reclined probe along with temperature, separately educed their each mathematic expressions and discussed the affection of temperature to inspection sensitivity and defects quantitative and orientation and solution in accordance with sound speed of ultrasound longitudinal wave change along with the temperature among a certain organic glass.
