摘　　要：本文介绍由O Cr17Ni4 Cu4 Nb材料制造的超高压缸体自增强处理试验结果,给出了四个缸体外壁面的p—ε_10曲线和其残余直力,与十二边形准则的计算结果相比较十分吻合。最后本文讨论丁以压力控制超应变度的合理观点。This article introduces the experimental result of autofrettaring techniques of ultra-high cvlinders which are made of 0Cr17N14Cu4Nh and the P-εωcharts and residual stress of four cvlinders outsidc-surfnce. Compared with the caleuiating res'ults of twelve-poly-gon criteria are given , these results are in accordar.ce. In the end , the article presents a reasonablc opinion to control the ultra-stain percent by pressuring in cvlinders.
