摘　　要：通过对传统蠕变松弛试验仪改造,用超声波测长法代替千分表测长法,用普通高强度螺栓代替特殊加工工艺应力螺栓,并就改造后的稳定可靠性进行了验证。可同时制作几个工装进行垫片试验,提高工作效率。The supersonic wave measuring length method will take the place of the micrometer measuring length method by reforming the traditional creep relaxation tester. In stead of using the stress bolt produing by special roaching process, the ordinary high strength bolt was used. At last, we verified the reliability of the equpment. We had made several tooling equipment for testing gasket, then our working effi- ciency had been improved.
