摘　　要：利用ＨＣＮ激光多道干涉仪，首次在ＨＬ－１Ｍ装置上在低混杂电流驱动（ＬＨＣＤ）期间观测到密度锯齿现象。分析表明，密度锯齿不是通常的ｑ＝１锯齿。The electron density sawteeth oscillations, which can be used to explore the particle behaviors in central plasma, have been first observed in the HL 1M tokamak using a multichannel HCN interferometer. Analysis results show that the electron density sawteeth activity is not due to the sawteeth oscillation on the q=1 surface and it is due to the mutual effect of lower hybrid wave and impurities in the plasma.
