摘　　要：计划在新疆奇台建设的110米射电望远镜(简称QTT)将位居国际一流大科学装置之列,成为世界最大的全向可转动射电望远镜.QTT在引力波探测、黑洞发现、恒星形成、星系起源等基础科学研究领域将发挥重要作用,并可发展应用于深空探测,如探月工程和火星、金星探测.QTT设计方案考虑多种科学目标的需求,其关键技术包括:大口径天线结构设计技术、天线主动面技术、大惯量机架精密伺服控制技术、超宽带馈源技术、低噪声放大器技术、多波束接收技术等.QTT关键技术的突破与应用,将促进我国信息、精密机械加工和自动控制等工程技术领域的发展.QTT各系统建设将以自主创新为主,通过国际合作引进和采用相关尖端技术完成.The 110 m radio telescope （QTT）, which is proposed to be built in Xinjiang Qitai, will be in the list of world-leading large scale scientific facilities, becoming the world＇s largest fully steerable radio telescope. QTT will play an important role in the field of fundamental science, such as gravitational wave detection, black holes, star formation and galaxy origin, and also be applied to deep space explorations, for example, Lunar Exploration Program and Exploration of Mars and Venus. The QTT design has considered various requirements for science goals, and its key technologies include： large-scale antenna structure design, antenna active surface, large inertia mechanism precision servo control technology, broad band feed, low-noise receiver, multi-beam technology, etc. The breakthrough and application of the key technologies will promote the development of engineering technology, including electronic information, precision machining and automatic control, etc. Through international cooperation, the QTT systems will base on self-dependent innovation and adopt related cutting-edge technologies to fulfill its construction.
