摘　　要：介绍了基于束流准直(BBA)的工作原理和系统组成,给出合肥800MeV储存环束基磁中心的测量结果,并以束基磁中心作为参考轨道,进行了全环校正。校正之后,剩余轨道的误差可以被控制在±0.1mm之内。The operation principle of the beam-based alignment (BBA) and the BBA system for Hefei Light Source (HLS) is presented. The measured results of beam-based magnetic center of quadrupoles are given. Then, the global orbit is corrected using the beam-based magnetic center of quadrupoles as a reference orbit. After the global orbit is corrected, the COD will be controlled within ±0.1 mm.
