导出了尘埃等离子体中固定粒子电荷分布的解析表达式，该表达式考虑了单粒子电荷极限的存在。通过与蒙特卡罗充电仿真结果的比较，验证了该表达式的正确性。考察了电荷极限的存在对不同电子离子密度比和离子质量值的相对重要性，并考虑了电荷极限对电荷分布的瞬态行为的影响。研究发现，随着电荷极限的减小，达到稳态电荷分布所需的时间显著减少，并且电荷极限的存在使得高频电荷波动相对于没有电荷极限的情况变得更为重要。
An analytical expression for the stationary particle charge distribution in dusty plasmas is derived that accounts for the existence of single-particle charge limits. This expression is validated by comparison with the results of Monte Carlo charging simulations. The relative importance of the existence of charge limits for various values of the ratio of electron-to-ion density and ion mass is examined, and the effect of charge limits on the transient behavior of the charge distribution is considered. It is found that the time required to reach a steady-state charge distribution strongly decreases as the charge limit decreases, and that the existence of charge limits causes high-frequency charge fluctuations to become relatively more important than in the case without charge limits.
