摘要
采用直线法在同一试件上同时标定残余应力测试中释放系数Ａ，Ｂ值和附加塑性压应变，减少了测试环节，取得了良好的结果。
The author makes use of straight line way demarcated at the same time A,B value of release coefficient in determination of remnant stress and additional plastic press strain in the same testpiece. The result has reduced measure and test link and obtained the better results.
