报道了负离子临界浓度下多组分等离子体中游动孤子的实验观测结果。缓慢幅度调制的扰动经历自调制并产生高幅度的局域脉冲。实验测得的游程孤子的幅度是附近载波幅度的3倍，与理论相符。将非线性薛定谔方程的数值解与实验结果进行了比较。
The experimental observation of Peregrine solitons in a multicomponent plasma with the critical concentration of negative ions is reported. A slowly amplitude modulated perturbation undergoes self-modulation and gives rise to a high amplitude localized pulse. The measured amplitude of the Peregrine soliton is 3 times the nearby carrier wave amplitude, which agrees with the theory. The numerical solution of the nonlinear Schrodinger equation is compared with the experimental results.
