A new form of Stokes drift formula can be obtaincd from the new horizontal displacement equation, which shows that under the third order approximation, the Stokes drift is proportional to the square of the amplitude of water particle.

• 由二次迭代的水平位移方程即可获得Stokes漂流公式的一种新形式,该形式表明,在三阶精度下Stokes漂流与所在深度的水质点的振幅A的平方成正比。
