给出有限深水斯托克斯波的一种新的近似解法，得到了与经典三阶斯托克斯波不同弥散关系。并与Ｓｋｅｊｅｌｂｒｅｉａ和Ｔａｄｊｂａｋｈｓｈｄ＆Ｋｅｌｌｅｒ的经典斯托克斯波的结果进行比较，发现在Ｋｄ较小处，差别比较明显。指出，它对精确确定斯托克斯波解，特别是确定高阶斯托克斯波的表达形式有重要的应用价值。
A new approximate solution of finite depth water Stokes wave is given, and the dispersion relation with classical third order Stokes wave is obtained. Compared with the classical Stokes waves of Skejelbreia and Tadjbakhshd & Keller, it is found that the difference is obvious at the smaller Kd. It is pointed out that it has important application value to accurately determine Stokes wave solutions, especially to determine the expression of higher order Stokes waves.
