本文研究了用衍射法测定钢轨残余应力的面积探测器的应用。本研究以西日本旅客铁道北陆线（JR-西）的钢轨为研究对象。由于滚动接触疲劳引起的裂纹，钢轨被拆除。本文介绍了用二维探测器测量中子应力的方法和相应的数据分析。
In this study, the authors investigated the application of the area detector for the purpose of evaluating residual stress in rails by means of diffraction technique. A rail used in the Hokuriku-Line of West Japan Railway Company (JR-West) was used as a specimen for this study. The rail was removed due to initiation of cracks caused by rolling contact fatigue. The present method refers to neutron stress measurement with a two-dimensional detector and corresponding data analysis.
