摘　　要：针对我国500 m口径球面射电望远镜(FAST)的圈梁变形监测,提出了位置差分数学模型,并进行了数据分析和验证。采用基于差分方法的FAST圈梁变形监测,使得圈梁的变形监测数据更加可靠,并为今后FAST使用差分测量方法提供数据参考。A difference method for FAST Ring Beam Deformation Monitoring is proposed in this paper. After elaborating 500 meter Aperture spherical radio telescope （FAST） deformation monitoring and the principles of the difference mathematical model in measuring, the differential data analysis has been made. This method has been validation finally. FAST ring beam deformation monitoring is based on the difference method, making the ring beam deformation monitoring data more reliable. This paper can also provide basis data for future reference on FAST measurement system.
