摘　　要：以HT -6M托卡马克在欧姆加热条件下的氧、碳杂质空间分布的实际测量结果及该装置背景等离子体的具体特征为基础 ,建立起杂质输运分析程序 ,并由此展开模拟分析 .结果表明 ,该装置氧、碳杂质的浓度分别为 5 %ne和 3 %ne(ne为电子密度 ) ,杂质输运行为是反常的 ;扩散系数为 2 0m2 ·s- 1,有效电荷数Zeff接近Based on the characteristic parameters of the background plasma and the experimental data of the spatial distribution for oxygen and carbon impurities in HT-6M tokamak under ohmic heating, a program for computing the impurity transport is established. The behaviour of impurity transport is analyzed. The results show that the density of oxygen and carbon is 5% n e and 3% n e separately, the behaviour of impurity is anomalous, the diffusivity is 2 0 m 2·s -1 ,and effective charge number is near 4.
