摘　　要：描述在合肥同步辐射储存环中观察到的频率为８７５．１ＭＨｚ和１５４１．５ＭＨｚ的两种纵向振荡，它们分别由高频腔的ＴＭ０１２和ＴＭ０３２高次模的阻抗引起．给出了这两种振荡与调谐杆位置及束流流强的依赖关系，并和理论计算的结果进行了比较．Two kinds of longitudinal oscillation were observed in HLS storage ring. They arise from the shunt impedances of the TM 012 -like mode and TM 032 -like mode of the RF cavity respectively. The beam current and tuner position dependencies of the amplitudes of the longitudinal oscillations were measured, and the results were discussed in comparison with the theory.
