摘　　要：介绍了充气夹心弹丸的基本结构、制作工艺和充气弹丸注入器的基本构成以及在HL-2A等离子体中注入的初步实验结果。实验中采用以聚苯乙烯为主的空心微球为载体,直径~0.76mm,壳体厚度~20μm,充满~1.5MPa的氘气的充气弹丸。实验结果表明,充气弹丸注入速度~200m·s-1,注入深度~12cm,加料效率~60%。Preliminary experiments of encapsuled pellet injection are carried out on the HL-2A device. Basic construction of the encapsuled pellet and manufacture technology are introduced. The encapsuled pellet is with the diameter ~0.76 mm, thickness of polystyrene shell ~20μm and internal deuterium pressure ~1.5 MPa. Experimental results show that the encapsuled pellet is intact during its flight path, and can be injected to the depth of ~12 cm with the velocity of 200 m·s-1. The fuelling efficiency is about 60%.
