我们给出了一个例子的超音速解决方案的一维稳态欧拉-泊松系统所产生的等离子体和半导体的建模。利用Schauder不动点定理证明了对应于大电流密度的超音速解的存在性。我们还显示在超音速区域的解决方案的唯一性。
We give an example of supersonic solutions to a one-dimensional steady state Euler–Poisson system arising in the modeling of plasmas and semiconductors. The existence of the supersonic solutions which correspond to large current density is proved by Schauder’s fixed point theorem. We show also the uniqueness of solutions in the supersonic region.
