摘　　要：用光谱学方法测量了HL-1托卡马克等离子体中性氢原子密度n_0的时空分布,氢原子流入通量Г_0。粒子约束时间τ_p及再循环系数R等,测得n_0约为10~9—10^(11)cm^(-3),Г_0为10^(15)—10^(16)cm^(-2)·s^(-1),τ_p为几毫秒到几十毫秒,R≈0.8。根据多次放电实验数据得到了有关的定标关系。实验表明,孔栏半径的大小对氢原子流入通量及粒子约束时间都有显著影响。孔栏在粒子再循环方面起主要作用。Using the spectroscopic method, the temporal profile of the neutral hydrogen atom density, the influxes Γ0 of hydrogen atom, the particle confinement time τp and the recycling coefficient R are measured in the HL-1 tokamak. The obtained results are: n0≈109-1011cm-3, Γ0≈1015-1016 cm-2. s-1, R≈0.8 and τp a few to several ten milliseconds. The concerned scalings are obtained from a large number of experimental data. Experimental results show that the influxes of hydrogen atom and particle confinement time are influenced obviously by the radius of limiter. The limiter also plays an important role in the recycling.
