The tool path planning method based on equidistant surfaces is suitable for machining convex-toric surface using slow tool servo technology. The proposed method has some reference values for processing optical elements having other surface shapes by slow tool servo technology.]]> 2020/7/6 10:23:21 QIU Xinyang, ZHANG Yanqin, WANG Hongbin 5true <![CDATA[Research and practice of the mechanical antennas based onrotating permanent magnet]]> 2020/7/6 10:23:21 ZHOU Qiang, SHI Wei, LIU Bin, WEI Zhihu, HE Panfeng, ZHANG Jiang 4true <![CDATA[Pulse encoding strategy using 3-level non-uniform quantizing]]> 2020/7/6 10:23:21 CHEN Jianbin, ZHANG Jiang, ZHOU Qiang, WEI Zhihu 3true <![CDATA[Disturbed electric field of nonmetallic cylinders in shallow sea]]> 2020/7/6 10:23:21 YU Peng, CHENG Jinfang, JIANG Runxiang 2true <![CDATA[Simulation and analysis of thermal and dynamic properties of super-pressure balloon during ascent]]> 2020/7/6 10:23:22 ZHU Rongchen, WANG Sheng, YANG Yanchu, LIU Qiang, CAI Jingjing 1true
