根据加德纳和欧拉方程研究了不同深度的两层海洋中中等幅度的内部孤子的传播。通过使用小参数（底部斜率）的渐近展开来获得解析解。将理论结果与数值模拟结果进行比较。讨论了脉冲传播期间孤子形状保持的可能性。结果表明，随着初始幅度的增加，脉冲偏离孤子形状的速度更快。
The propagation of internal solitons of moderate amplitude in a two-layer ocean of variable depth is studied in terms of the Gardner and Euler equations. An analytical solution is obtained with the use of asymptotic expansions on a small parameter (bottom slope). The theoretical results are compared with the numerical modeling results. The possibility of soliton shape preservation during pulse propagation is discussed. It is obtained that, as the initial amplitude increases, the pulse deviates from the soliton shape more rapidly.
