摘　　要：Dear Readers:Large radio telescopes are important infrastructure for deep space navigation,astrophysics,astrometry,and other fields.Building a large radio telescope requires overcoming a series of technical challenges such as high-precision pointing,high reception efficiency,low-temperature wide-band reception,a complex and flexible control system,comprehensive performance testing,and gravity deformation correction techniques.Shanghai Astronomical Observatory,CAS,in collaboration with multiple research institutions,has implemented multiple key technologies and built the Tianma 65 m radio telescope(TMRT),with advanced performance and complete functionality.The overall performance has reached an international advanced level,greatly enhancing the orbital determination capability of China's lunar exploration satellites and deep space probes,and the telescope has demonstrated international VLBI observation and radio astronomy observation research capabilities.The six papers in this special issue introduce the research and development technology and experience of the TMRT from multiple aspects.The papers provide reference value for the research and application of subsequent radio telescopes.
