摘　　要：本文用光谱学方法研究在HL-1装置上LHCD及ECRH等离子体、弹丸注入等离子体、偏压电极与偏压孔栏等离子体放电的粒子约束特性.结果表明,在弹丸注入及使用正向偏压电极与偏压孔栏期间,等离子体粒子约束得到改善.较低密度下(n(?)<2.0×10^(13)cm^(-3)),LHCD脉冲期间粒子约束得到改善;而当密度n.大于2.0×10^(13)cm^(-3)时.等离子体约束变坏.ECRH脉冲期间粒子约束得不到改善.The particle confinement characteristics of plasmas in various discharges in the HL-1 tokamak have been studied by means of spectroscopy , including discharges with LHCD . ECRH,pellet injection,biased electrode and biased limiter.In the experiments of pellet injection, biased electrode and biased limiter with positive voltage,the particle confinement has been improved. During the LHCD period,the particle confinement was improved when ne < 2. 0 ×1013cm-3;but deteriorated when ne> 2. 0× 1013cm-3 .In the experiment of ECRH, the particle confinement has not been able to be improved.
