摘　　要：在HL-1M装置上用分子束注入等离子体的气体加料方法提高了等离子体的电子密度。当线平均电子密度从 4× 10 13cm-3 上升到 7× 10 13cm-3 时 ,利用多道辐射损失测量系统测量到来自等离子体边缘的非对称辐射现象。在强场侧等离子体辐射损失功率密度大大高于弱场侧而线平均电子密度、OⅥ杂质谱线和HαPlasma electron density was increased by using the method of gas fuelling with molecular beam injection in the HL 1M tokamak.As the line average electron density n e  increases from 4×10 13 cm -3 to 7×10 13 cm -3 a multifaceted asymmetric radiation from the edge (MARFE) was measured with a multichannel radiation loss measuring system.Radiation loss power density on the high field side is much larger than that of the low field side,impurity OⅥ line radiation and H α,VUV increase Considerably.
