中文摘要：

基于浅水长波假定，给出了正五边形封闭港湾内水波共振的解析表达式；并采用Boussinesq模型对该表达式进行验证。结果表明，正五边形封闭港湾内主要体现为类似一维港湾的单一波向上的共振，而产生共振的主要原因是壁面之间形成的驻波。

英文摘要：

Based on the linear shallow water approximation, this paper presents analytic solutions for oscillation within a closed regular pentagon-shaped harbor. The Boussinesq model was used to verify the equation. The results show that oscillations in the closed regular pentagon-shaped harbor are similar to those in a one-dimensional water flume, and the resonance is mainly due to the standing wave between different walls of the harbor.
