In the open ocean, due to very long wavelengths, the wave height is small (only 1-2m), this wave is not rough, but the spread of to near coastal areas, due to the gradual shallowing water depth, seabed resistance is increased, wave deformation, wave height increases rapidly (up to 10 meters), will be the formation of waves rushed into the land.

在开阔的大洋中，由于波长很长，波高不大（仅1—2m），这种波浪并不汹涌，但传播到接近海岸地带，由于水深逐渐变浅，海底阻力加大，波浪变形，波高急剧增大（可达10余米），便形成巨浪冲向陆地。

The linear dispersion relation of the enhanced equations is the Pad\'{e} [4,4] expansion of the linear Stokes dispersion relation, the accuracy of which is acceptable even when the relative water depth is as large as 1.0. Its nonlinear property and shoaling gradient are also improved.

改进后方程的线性色散关系达到了一阶Stokes波色散关系的Pad\'{e}[4，4]近似，在相对水深达1.0的强色散波浪时仍保持较高的准确性，并且方程的非线性和线性变浅率都得到了不同程度的改善。

In shoaling process, the main peak frequency of broken wave spectra moves to lower frequency. With decreasing relative water depth, both the ratios of wave spectral energy at twice and triple peak frequency to main peak frequency increase. and when the value of the nonlinear parameter increases, both the ratios increase, too. The Stokes third order wave theory has the same tend but overestimates the value quantitatively.

波浪浅化时，碎波后主频频率有往低频移动之现象，且波浪进入浅水区，相对水深减小，非线性参数Ursell number越大时，二倍主频及三倍主频与一倍主频能量比值均有增加之现象，与 Stokes三阶理论有相同之趋势，但实验之比值在定量上小於Stokes三阶理论值。

The distribution patterns of Tamarix chinensis population under the environmental gradient of different water table depth were analyzed using two fractal analysis methods-box dimension and information dimension.

The results show that: 1 sand-sandrock vadose zone structure ""is the critical factor for drought resistent vegetations because of its abundant moisture contents; 2. the relationship between the drought resistant plants and water table depth is not close.

认识到风积沙覆基岩型包气带结构有利于土壤水富集，是鄂尔多斯盆地北部沙蒿、沙柳等耐旱喜沙植被分布与生长的决定性因素，对维系盆地北部生态系统有重要作用；而地下水位埋深与沙蒿等耐旱植被生长间的关系并不密切。

The reliability of proposed model is verified by the data of the water depth in the drainage and emptying tunnel of a reservoir as well as the experimental result using hydraulic method. The average relative errors are 5.01% and 0.96% respectively.

通过与某水库放水兼放空洞水深实测数据及采用传统水力学方法计算的经验值的对比分析，平均相对误差分别为5.01%和0.96%，验证了模型的可靠性。
