建立了一个适用于局部开放系统的无边界粒子模拟模型，该模型中内部等离子体与外部等离子体源（如电流发生器）连续、平滑地连接。我们提出了这种形式主义，并检查这个过程的适用范围。该方案确保了在每个时间步通过系统边界的传出和传入粒子通量之间的平衡。将基于此原理开发的数值计算程序应用于离子声双电层系统，并与恒流源相连，验证了程序的正确性和有效性。
A boundary-free particle simulation model, applicable to a local open system in which the internal plasma is continuously and smoothly connected to an external plasma source such as a current generator, is developed. We present this formalism and examine the range of applicability of this procedure. This scheme assures a balance between the outgoing and incoming particle fluxes through the system boundaries at each time step. The numerical code developed on this principle is applied to an ion acoustic double layer under the condition that the system is connected to a constant current generator to confirm the soundness and validity of the code.
