摘　　要：以高压聚乙烯管式反应器为例,对自增强残余应力松弛规律进行研究,分析自增强残余应力的松弛特点、原因和机理,着重研究自增强残余应力松弛的影响因素及其对残余应力的影响情况。Taking the tubular reactor of high pressure polyethylene from autofrettaged facilities for example,the paper carries on a research about the relaxant regularity of autofrettaged residual stresses,analyzes characteristics,reason and mechanism of dint of autofrettaged residual stress- es.and it places emphasis on influential factors to the relaxation and these factors' impact on the residual stresses.

关 键 词：自增强 残余应力 松弛
