摘　　要：在对地下结构的探测过程中,重力梯度仪器的研制及其科学的布设方式已经成了一个世界关注的研究课题。笔者介绍了目前世界上存在的基于扭矩和差分加速度计两种测量原理的重力梯度仪,并对其测量原理进行简要描述。然后对基于光学和原子干涉重力梯度测量仪器进行描述,最后介绍了作者提出的重力梯度测量光路,为自主研发绝对重力梯度仪提供技术参考。：During the exploration of the underground medium structure, the gradiometer as well as its new deployment styles for various applications has become an important research topic of world concern. This paper describes various kinds of gradiometers based on tor- sion balance and difference algorithm and deals with the principle of each instrument. In addition, the absolute gradiometers based on the laser and atom interference are also described. In the last part of this paper, the design of the measurement light path is presented. The results obtained by the authors can serve as the technologic reference for developing gradiometer.
