摘要 Gross-Pitaevskii方程的精确解对理解玻色-爱因斯坦凝聚动力学演化具有重要作用.应用sine-cosine方法对Gross-Pitaevskii方程的简化模型进行了求解.获得了孤波解、三角函数周期波解等一些不同形式的精确解. The construction of exact solutions of Gross-Pitaevskii equation plays an impor- tant role in understanding the dynamic evolution of Bose-Einstein condensates. The sine- cosine method is used to obtain the exact solutions of simplified model of Gross-Pitaevskii equation. These solutions include solitary wave solutions and trigonometric function periodic wave solutions.
