摘　　要：极端和中等质量比旋近系统是空间引力波探测器的重要波源,是检验强场条件下的引力理论、测量黑洞本质、研究星系动力学等重要科学问题的重要工具.这种波源产生的引力波信号持续时间往往可达数年、强度很弱、构成复杂.为了成功探测到极端和中等质量比旋近系统,构建精准高效的波形模板和信号识别技术就尤为重要.本文首先回顾了波形计算的技术,模板构建的方法和进展,然后讨论了信号识别技术的发展和现状.Extreme and intermediate mass-ratio inspirals are important gravitational wave sources for space-borne detectors,and they are important tools for testing the theory of gravity under strong field conditions,measuring the nature of black holes,studying the dynamics of galaxies,and other important scientific issues.The gravitational wave signals generated by such sources often have durations of several years,are very weak and have complex compositions.In order to successfully detect extreme and intermediate mass-ratio inspirals,it is particularly important to construct accurate and efficient waveform templates and signal identification techniques.In this paper,we will first review the techniques of waveform computation,methods and advances in template construction,and then discuss the development and current status of signal recognition techniques.
