| 摘 要： | 研究了HL－1M装置上锁模不稳定性和密度极限破裂。锁模不稳定性通常出现在低密度的实验中，在软X射线和Mirnov磁扰动上都观察到了频率相同的先兆振荡，其时间尺度为10ms。边3比温度的然下降是产生模不稳定性的重要标志。锁械出现几毫秒后时常发生大破裂。提出了抑制锁械的稳定性的建议。

| Abstract: | Locked mode instability and density limit disruption have been studied in the HL 1M tokamak. Locked mode instability often appears in discharges with low density. Both precursors on the soft X ray and the Mirnov perturbation have same frequency and a time scale of 10ms. The drop of edge temperature is an important feature of appearance of the locked mode instability. Major disruption often takes place in a few milliseconds after mode locking. Some suggestions to suppress locked mode instability are proposed. |
