摘　　要：研究了HL 1M装置上弹丸和分子束加料的粒子输运。在研究粒子输运时拟合了粒子源分布,利用调制送气模型研究了分子束送气时的粒子输运。由弹丸注入后较长时间内密度的自然衰减研究了粒子输运,给出了一种简单的研究弹丸注入后粒子输运的方法。计算表明,分子束和弹丸注入改善了等离子体的粒子输运特性。将计算结果与实验测量进行了比较。The particle transport during pellet fuelling and MBI in the HL-1M tokamak is investigated.Assuming the operator in transport equation is linear,we emphasize on investigating the solution of transport equation.Particle source function was fit in with a curve under steady state gas puffing.By means of gas puffing modulation,diffusion coefficient and inward velocity were calculated under gas puffing and MBI modulation experiment on the HL-1M tokamak.From long density attenuation times,the diffusion coefficient and inward velocity were calculated after pellet injection.The results show that the MBI and pellet injection improve the transport property of plasma particles.
