摘　　要：用HL-2A装置下偏滤器室内的红外测温系统和靶板朗缪尔探针系统分别测量了HL-2A偏滤器靶板上的等离子体沉积功率分布,并进行了对比分析。对HL-2A外偏滤器靶板热流的径向和环向沉积结构分布特征的分析表明,HL-2A装置上靶板热流在径向上基本上呈指数衰减分布,其衰减长度在5~7mm左右。The plasma deposition power distribution on the divertor plate was measured by infrared temperature measurement system and Langmuir probe system in the lower divertor chamber of HL-2A tokamak.The distribution characteristics of the radial and toroidal deposition structures of the heat flow of the target plate in the outer divertor were analyzed.The results show that the heat flow of the target plate on the HL-2A tokamak basically presents an exponential decay distribution in the radial direction,and its decay length is about 5~7mm.
