一、引言和展望无损检验的主要任务是确定缺陷的性质和大小,找出缺陷的可检出极限。检验方法不同,由检验结果确定缺陷性质和大小的难度也不同。(?)图1 各种可行的无损检验方法的检验效果1—优;2—良;3—中;4—差。一、引言和展望无损检验的主要任务是确定缺陷的性质和大小,找出缺陷的可检出极限。检验方法不同,由检验结果确定缺陷性质和大小的难度也不同。(?)图1 各种可行的无损检验方法的检验效果1—优;2—良;3—中;4—差。
I. INTRODUCTION AND OUTLOOK The main task of NDT is to determine the nature and size of the defect and to find the detectable limit of the defect. Different test methods, the test results to determine the nature and size of the defect is also different. (?) Figure 1 The test results of a variety of viable non-destructive testing methods 1-excellent; 2-good; 3-in; 4-poor. I.
