摘　　要：本文讨论了低温压力容器的主要失效模式,并从断裂力学的角度对脆性断裂进行了分析,对压力容器从业人员更为深刻的理解低温压力容器的设计制造特殊要求有一定的参考意义。The pressure vessel in low temperature service is a significant branch in pressure vessels. This paper discusses the main failure modes of pressure vessel in low temperature service, and explains the brittle fracture in fracture mechanics, and has a certain reference to understanding the special requirements in design and manufacture of the pressure vessel in low temperature service.

关 键 词：低温压力容器 失效模式 脆性断裂 断裂力学
