摘　　要：声发射技术能够提供缺陷在应力作用下的动态信息,适于评价缺陷对结构的实际有害程度。因此采用声发射技术对某电厂汽包中的超标缺陷进行检测,能够更准确地评价缺陷的活动性及对汽包的危害性,为缺陷的处理提供进一步的依据,确保电站机组安全稳定运行。Acoustic emission technique could provide defect in the dynamic information under stress,and evaluate defects on the structure for the actual degree of harm.Therefore,adopting acoustic emission technique had detected defects in the drum of a power plant,it could more accurately evaluate the activity and danger of defects in the drum of boiler,further provide the basis of treatment for the defect,and assrue safety of generator.
