摘　　要：采用遗传算法模拟了Dα的光谱轮廓,模拟曲线与实验中观察到的轮廓符合得非常好。分析模拟的结果表明,在HL-1M装置边缘等离子体中,存在一种H粒子群和三种D粒子群,它们有各自的温度和粒子数比例。Line shape spectroscopy is a valuable tool both for diagnostic, and for understanding the basic atomic processes in the boundary region of magnetically confined fusion plasmas. The Do line profiles are modeled with genetic algorithm. The modeling profiles are in good agreement with the line profiles obtained in experiment. The results of this analysis suggest that there are one population of hydrogen and three populations of deuterium with different temperatures and population ratios.
