摘　　要：在HL-IM氘放电过程中,利用多通道光谱分析仪Ⅳ(OMA 4)系统测量了H_α(氢)和D_α(氘)的谱线强度之比,进而得到氢和氘的粒子密度之比。测量结果表明:在HL-1M托卡马克氘放电开始阶段,氢氘比随时间迅速增大;在电流平顶阶段,从总体上看,氢氘比随时间缓慢增大;多次放电以后,氢氘比没有明显减小或减小得非常缓慢。During D exchanging in the HT--lM Tokamak, the spectrum line intensity ratio of H and D was measured withOMA 4 system. At beginning of exchanging, the ratio of H and D rapidly rises. At the top of the toroidal current, the ratioslowly rises. After many exchanging, the ratio doesn' t obviously decline or very slowly declines.
