| 摘 要： | 提出一种利用声发射技术判定压力容器缺陷来历的方法。通过水压试验时的声发射监测，利用凯塞效应原理对被检出缺陷是漏检原始缺陷还是使用后形成缺陷进行判定，为基于断裂力学理论的安全评定提供可靠保证。

| Abstract: | A new method using acoustic emission technology to determine the defect origin of pressure vessels found in regular inspection was developed. Depending on the acoustic emission during the hydraulic pressure test, it could be determined whether the defect was originally formed or not with the help of Kaiser effect principle. The safety assessment of pressure vessels based on fracture mechanics would be more reliable by the use of the method. |
