摘　　要：介绍了Frequency Map Analysis在合肥光源上的应用,通过粒子跟踪得到加入六极以及八极磁铁后合肥光源的tune漂移,根据得到的tune图分析高阶共振情况计算发现通用光源模式(GPLS)lattice 处在弱共振带上．For the Phase 2 of HLS （Hefei Light Source） Project, many sextupoles and octupoles have been installed in the machine to improve the operation condition. These nonlinear elements will introduce nonlinear effects to the beam dynamics. In this paper, we apply Frequency Map Analysis to the HLS ring. By analyzing the resonance lines on the tune map, we find that the calculated lattice of GPLS mode lies on the weak chaotic zone, and the operating mode is better.
