介绍了用A显示连续波反射法检测最小不连续性的模型,理论分析了影响超声能检测出的最小不连续性尺寸的主要因素,并用准连续波试验研究了这些因素的影响规律,给出了相应结论。
A continuous wave reflection method is introduced to detect the minimum discontinuity. The main factors affecting the minimum discontinuity size detected by ultrasonic energy are theoretically analyzed. The quasi-continuous wave experiment is used to study the influence rules of these factors. The corresponding conclusion.
