摘　　要：空间引力波探测已经成为国际宇宙学研究热点,欧美合作的LISA空间引力波探测计划和中国的太极、天琴空间引力波探测计划在合作与竞争并存的良好态势下迅猛发展.作为空间引力波探测的核心载荷,引力参考传感器在发射入轨前必须做相应的地面测试.为了解国内外利用扭摆对引力参考传感器进行地面测试的研究进展,本文简要介绍了引力参考传感器和利用扭摆对引力参考传感器的测试方法,总结了国内外扭摆的研究进展,并对用扭摆对引力参考传感器进行地面测试的发展趋势提出了展望,以期为太极计划引力参考传感器的研制和地面测试提供参考.Space gravitational wave detection has become a hotspot in international cosmological research.The European and American Laser Interferometer Space Antenna space gravitational wave detection program and China’s Taiji and Tianqin space gravitational wave detection programs are rapidly developing with simultaneous cooperation and competition.As the core load for space gravitational wave detection,gravitational reference sensors must undergo corresponding ground testing before being launched into orbits.To understand the research progress of ground testing of gravitational reference sensors using a torsion pendulum at home and abroad,this article briefly introduces gravitational reference sensors and their torsion pendulum-based test methods,summarizes the research progress of the use of torsion pendulums at home and abroad,and provides a review of the use of torsion pendulums to test gravitational reference sensors.The development trend of gravitational reference sensors for ground testing is proposed to provide a reference for their development and ground testing for the Taiji space gravitational wave detection program.
