摘　　要：本文描述HL-1装置器壁碳化,观察了碳化前后氢的约束时间和再循环现象,同时还观察了加抽气孔栏条件下粒子约束时间和再循环的变化。实验表明,碳化后氢的再循环增大,使用抽气孔栏可以控制壁附近边缘等离子体的粒子密度,粒子约束时间比不用抽气孔栏增大17.7％,再循环系数减小13.2％。The carbonization of the vessel wall in the HL-1 tokamak is described in this paper. The particle confinement times of hydrogen and hydrogen recycling before/after carbonization,as well as those with pumping limiter, have been observed. The results show that, the hydrogen recycling with carbonization is increased; the use of a pumping limiter makes it possible to control the particle density of the edge plasma near the wall; the particle confinement time with the pumping limiter is 17.7% longer than that without the pumping limiter, and correspondingly, the recycling coefficient decreases by 13.2%.
