摘　　要：主要介绍了HL-1M托卡马克装置3种加料方式所得的密度特性结果。用弹丸注入(PI),超声分子束注入(SMBI)和常规脉冲送气(GP)获得等离子体电子密度N_e分别为5.3×10^(19)m^(-3),8×10^(19)m^(-3)和7×10^(19)m^(-3)。前者获得的能量约束时间τ_e却比后者高30％以上。由H^a信号及软X信号(SX)的时空分布分析表明,能量约束差别是加料粒子沉积区域不同所致。The main experimental results with three type of fueling method used on HL-1M have been presented. The maximum electron densities of 5.3 ×1019m-3, 8.0×1019m-3 and 7.0×@ 1019m-3 were obtained by Pellet Injection (PI) , Supersonic Molecular Beam Injection(SMBI), and Gas puffing(GP) respectively. The energy confinement time τe of 26 ms obtained by PI is 30% greater than GP discharge, it is created by different depositing area of fueling particles.
