摘　　要：介绍了合肥光源(HLS)二期工程储存环调试过程中遇到的一些现象,并对这些现象进行了初步定量或定性的分析．在现有硬件条件的基础上,采取了一些相应的措施,取得了一定的效果,HLS通用模式储存束流超过300mA,寿命好于8h,达到了设计要求．The main subsystems of the Hefei Light Source (HLS) storage ring were upgraded in the Phase Ⅱ project of the NSRL. Some phenomena, occurred in the commissioning of the HLS storage ring, were simply described and analyzed in this paper. Firstly, the performance of the injection system was analyzed by the numerical tracking study. Then the adjustment of the RF system was explained with the traditional Pederson model. The effects of the octupole system were expressly revealed by the beam stability diagram with and without octupoles. Finally, the linear optics compensation of the super-conducting wiggler magnet was introduced briefly. Generally, these analyses basically agree with the physical phenomena and maybe helpful for the improvement of the HLS storage ring.
