摘　　要：应用外压和轴向压缩同时作用下的安全工作条件,对某夹套设备进行设计计算分析,说明了温差应力对外压容器失稳的影响,并提出在设计中应考虑的问题和解决方案。The working condition that the vessel was subjected to external pressure and axial pressure simultaneously was taken into account, the calculation for this jacketed vessel was carried out. The influence of thermal stress to the instability of the vessel was analyzed. Then, the problems which may appear in the design and the solutions for these problems were presented.

关 键 词：夹套容器 温差应力 安全工作条件
