摘　　要：讨论了使用手工接触法纵波直探头进行超声检测时,在被检测材料中发生的波型转换及波型转换的原理。通过理论分析、数学运算及验证试验,得出结论:接触法纵波垂直入射超声检测时,在被检材料中同样会发生波型转换。This paper discusses the wave-transition theory and puts forward that wave-transition occurs in the examined material when straight beam probe is used with contact method.Through theoretical analysis,mathematical calculation and verification test,it is concluded that the wave pattern conversion will also occur in the tested material even if the vertically incident ultrasonic longitudinal wave is employed.
