Such a relation isbeing supported by experimental results obtained in our laboratory. The error in stress measurements along axial direction of a cylindrical surfaceand certain problems encountered in the X-ray stress measurements of anomalous-ly shaped machine parts are discussed based on the above formula. 收稿日期: 1979-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 李家宝 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1979/V15/I3/421 [1] 金属研究所疲劳研究组,金属学报,13(1977) ,1． [2] 史连友,待发表工作.
