摘　　要：讨论了有界等离子体区域含待定边界条件导体时,二维准静电场方程与边界条件的耦合问题。通过典型问题的具体分析,提出处理这种边界条件的PIC算法。将其用于气体放电等离子体吸波管的数值模型,给出空间电势的正确分布。研究结果对丰富PIC粒子模拟程序的应用具有重要的意义。In this paper, the two - dimensional numerical solutions of the electrostatic fields in plasma region with undecided conductor boundary conditions are discussed. Methods of processing such boundary conditions including conductor within plasma or at the boundary are considered. On the basis of this work, the potentials in a gas dis- charge absorption unit fixed on a conductor surface of an object is obtained. The method can be used in PIC particle simulation code to enrich its application in solving such boundary problems.
