在HL-1 M装置等离子体物理实验中，采用了吹气、弹丸和超声分子束注入三种加料方式。利用Hα发射率分布等值线图分析和估算了弹丸和分子束的穿透特性和平均速度。在HL-1 M装置上，弹丸穿透深度达0.26m，弹丸在等离子体内的平均速度小于在等离子体外的平均速度。SMB从低场侧注入等离子体，其平均速度大于1 km s-1。
In plasma physics experiments of HL-1M tokamak, three refuelling methods (gas puffing, pellet and supersonic molecular beam (SMB) injection) were used. The penetration characteristics and the average speed of the pellet and molecular beam were analysed and estimated by means of contour plots of Hα emissivity distribution. On HL-1M tokamak, the penetration depth of the pellet was up to 0.26 m, and the average speed of the pellet inside the plasma was less than that outside the plasma. The SMB was injected into the plasma from the low-field side and its average speed was more than 1 km s-1.
