先前报道的非线性 Vlasov 方程的数值研究已扩展到对两流不稳定性的深入研究。一维电子等离子体的极不稳定的初始条件随着时间的推移而变化，直到等离子体的状态变得基本上与时间无关。正如先前推测的那样，电场和分布函数似乎都具有非均匀平衡的特征（Armstrong 1966）。
Previously reported numerical investigations of the non-linear Vlasov equation are extended to an intensive study of the two-stream instability. Strongly unstable initial conditions for the one-dimensional electron plasma are followed in time until the state of the plasma has become essentially time independent. Both the electric field and the distribution function appear to be characteristic of an inhomogeneous equilibrium, as previously conjectured (Armstrong 1966).
