The freak oscillation in one-dimensional dusty plasma is studied numerically by particle-in-cell method. Using a perturbation method, the basic set of fluid equations is reduced to a nonlinear Schrödinger equation (NLSE). The rational solution of the NLSE is presented, which is proposed as an effective tool for studying the rogue waves in dusty plasma. Additionally, the application scope of the analytical solution of the rogue wave described by the NLSE is given.
采用粒子模拟方法对一维尘埃等离子体中的反常振荡进行了数值研究。通过摄动方法，将基本的流体方程约化为非线性薛定谔方程（NLSE）。给出了 NLSE 的有理解，该解被提出作为研究尘埃等离子体中反常波的有效工具。此外，还给出了 NLSE 描述的反常波解析解的应用范围。
