The objective of this two-year U.S.-China research project on gravitational radiation between Peter Michelson, Stanford University and Enke Hu of Zhongshan University is to coordinate experiments to detect gravity waves between existing detectors at Stanford and Zhongshan University. The ultimate objective is to establish the existence of gravitational radiation, a fundamental form of energy, whose existence was predicted by Einstein and others over sixty years ago. The investigators will continue collaboration that began two years ago under the U.S.-China Program. They propose to carryout a long-term (one-year) coincidence observation with existing detectors, work on improving technology of cryogenic (cold temperature) detectors and begin a feasiblity study of a low frequency gravity wave detector. The establishment of a detector in Southeast China is signi>icant for this international experimental effort since it is essential for the successful detection of gravity waves that geographically dispersed detectors be used to establish simultaneous coincidences. The establishmen> of a base in Southeast China fills a geographical gap in the worldwide detector network. Results from the coincidental experiment are expected to contribute to the advancement of detector technology as well. This project fulfills the U.S.-China Program's objective of promoting mutually beneficial research to advance scientific knowledge through the combined efforts and abilities of American and Chinese scientists.

这项为期两年的中美重力辐射研究项目由斯坦福大学的彼得·迈克尔逊（Peter Michelson）和中山大学的胡恩克（Enke Hu）共同完成，目的是协调斯坦福大学和中山大学现有探测器之间的重力波探测实验。最终目标是证实引力辐射的存在。引力辐射是能量的一种基本形式，早在60多年前，爱因斯坦等人就预言了引力辐射的存在。调查人员将继续两年前在美中项目下开始的合作。他们建议用现有的探测器进行长期（一年）的重合观测，努力改进低温探测器的技术，并开始低频重力波探测器的可行性研究。在中国东南部建立一个探测器对这一国际实验工作具有重要意义，因为使用地理上分散的探测器来建立同步巧合是成功探测重力波的关键。在中国东南部建立基地填补了全球探测器网络的地理空白。巧合实验的结果也有望为探测器技术的进步做出贡献。该项目实现了美中合作项目的目标，即通过中美两国科学家的共同努力和能力，促进互利研究，推动科学知识的发展。
