摘要:

利用一个简单的水囊电子分布函数,找到了相对论性大振幅等离子体波在接近破波极限时所形成的奇点结构。破碎波中的电子密度分布具有典型的“峰孔”形式。获得了热裂等离子体中电场的最大值,并与冷等离子体极限进行了比较。对不同初始电子分布函数的计算机模拟结果与理论结论一致。

英文摘要:

The structure of the singularity that is formed in a relativistically large amplitude plasma wave close to the wavebreaking limit is found by using a simple waterbag electron distribution function. The electron density distribution in the breaking wave has a typical "peakon" form. The maximum value of the electric field in a thermal breaking plasma is obtained and compared to the cold plasma limit. The results of computer simulations for different initial electron distribution functions are in agreement with the theoretical conclusions.
