1.概述引力波探测是验证广义相对论以及检验其它与之并行的引力理论正确性的一个重要手段。1976年中山大学引力物理研究室开始了常温共振型引力波探测系统的建设,经过模拟实验、试运转和技术改进等几个阶段,于1984年正式运转(图1)。目前用于引力波探测的有共振型天线、激光干涉和宇宙飞船多普勒跟踪三大类方法。其中用高Q值材料制成并置于超低温中的共振天线具有最高的灵敏度。理论计算表明,只有大质量、高速运动的天体才有可能
1. Overview The detection of gravitational waves is an important means of verifying general relativity and testing the correctness of other gravitational theories in parallel. In 1976, Sun Yat-sen’s Gravitational Physics Laboratory began the construction of a normal-temperature resonant gravitational wave detection system. It was formally operated in 1984 after several experiments including simulation experiments, trial operation and technical improvement. At present, there are three types of methods for the detection of gravitational waves: resonant antenna, laser interference and spacecraft Doppler tracking. Resonant antennas made of high-Q materials and placed in ultra-low temperatures have the highest sensitivity. Theoretical calculations show that only large-mass, high-speed celestial bodies are possible
