摘要
采用纵波直探头对一系列不同深度处的人工反射体进行测量,绘制出该探头实际声束扩散角,并与理论计算的声束扩散角相比对,形象的展示出理论与实际的差别,为实际检测过程中缺陷性质的判断提供依据。
The actual beam spread angles of a longitudinal wave normal probe are plotted by measureing a series of artificial reflector in the the6retical angles to turn out the difference between the actual and theoretical values, which offers the referenees to evaluate defects in practise.
