In order to rule the concave grating with a long focal length  the diamond carriage with elastic thimble mode is designed and manufactured. It is available not only to rule plane grating  but to concave grating with a long focal length. The mathematic expression between the curvature radius of circular arc cutting edge of ruling tools for grating and the curvature radius of concave grating  the caliber of grating and the size of transverse direction of bit tool are given. The span of curvature radius of circular arc cutting edge is analyzed theoretically. The concave metal grating with 30m curvature radius for 10.6m laser system is manufactured. The testing result shows that the quality of groove is perfect and the diffraction efficiency is more than 95.6 percent. 2010 IEEE.   Investigation of superplasticity in a Ni50Al20Fe30 intermetallic compound 期刊论文 Materials Letters, 2001, 卷号: 51, 期号: 4, 页码: 342-346 W.
