利用分裂格式算法对一维非磁化等离子体的非线性Vlasov-Poisson系统的解进行了数值分析，该系统对应于麦克斯韦平衡附近的无阻尼行波。数值结果清楚地支持这种波的存在，并证实存在一个临界相速度，低于这个速度就不能构造这种波。
Solutions of the full nonlinear Vlasov–Poisson system for a one-dimensional unmagnetized plasma that correspond to undamped travelling waves near Maxwellian equilibria are analysed numerically using the splitting scheme algorithm. The numerical results are clearly in favour of the existence of such waves and confirm that there is a critical phase velocity below which they cannot be constructed.
