对无限长冰层覆盖水域下波动的弥散方程进行了简化，利用波能通量法计算了波浪传入冰层覆盖水域后的变形，讨论了考虑冰层的弹性位能对计算波浪进入冰层覆盖水域后波高变化的影响，得到了无量纲参数Ｔ2~(１／ｇ／ｄ)，与波高变化比值Ｈ_ｉ／Ｈ的曲线，分析了入射周期Ｔ，水深ｄ，冰厚ｈ_ｉ等对冰层内应力的影响。
The dispersion equation of wave motion under the infinite ice covered waters is simplified. The wave energy flux is used to calculate the deformation after the wave is introduced into the ice covered waters. The effect of the elastic potential energy of the ice on the calculation of the wave entering the ice The curve of the dimensionless parameter T2 ~ (1 / g / d) and the wave height change H_i / H was obtained. The effects of the incident period T, water depth d, ice thickness h_i, Effect of stress.
