摘　　要：根据我国压力容器在役检验和安全评定的要求，在美国ＥＰＲＩ的Ｊ积分工程方法及英国ＣＥＧＢＲ６失效评定曲线的基础上，考虑了我国压力容器用钢的特点和其他有关影响因素，如屈服平台、焊接、结构、应变时效和温度等，提出了我国压力容器缺陷失效评定曲线的建议。According to the requirements of inservice check andsafety assessment of the Chinese pressure vessels, andbased on the J integral engineering method of the USAEPRI and the UK CEGB R6 failure assessment curves.some suggestions of failure assessinent curves of the de-fects of the Chinese pressure vessels were proposed refer-ring to the characteristics and other related factors,such asyield plateau. weld. structure. strain ageing. and tempera-ture,of the steel used for the Chinese pressure vessels.
