| Abstract: | Based on the theory of ultrasonic flaw deletion, this article contrasts and amalyses the results of inspection and measusement of the flaws, such as cracks on metal surface,artificial cracks.in metal and the cracks caused by fatigue.This article puts farward the principles used to determine the sensitivity of inspection and measurement and the practical methods of inpection and measurement. |
