摘　　要：使用EFIT程序设计了HL-3装置雪花偏滤器位形,研究了雪花位形对HL-3装置极向场(PF)线圈电流变化的敏感性。研究发现:当PF线圈电流变化达1%时,标准雪花偏滤器转变为雪花加位形或是雪花减位形;当PF线圈电流变化超过8.8%时,雪花减位形在大偏离度下能够获得平衡位形,而雪花加位形难以获得收敛结果。The configuration of the HL-3 snowflake divertor by using the EFIT program was designed,and the sensitivity of the snowflake configuration of HL-3 tokamak on the individual lower poloidal field(PF)coil current was studied.It was found that when the individual lower PF coil current only changes by 1%,the standard snowflake divertor immediately changes to a snowflake plus configuration or snowflake minus configuration,and when the individual lower PF current changes above 8.8%,the snowflake minus configuration can reach a equilibrium configuration with a large deviation,while the convergence result is difficult to be obtained under the snowflake plus configuration.
