中文摘要：
利用JASON1测高数据进行海浪周期反演计算，在比较几种反演方法的基础上，利用ERA-40模型对计算结果进行检核与分析，通过数值结果表明，CS算法精度最低，CSG2算法最优，CSG1算法、Hwang算法及ZT算法相当，其原因在于CS算法主要从理论出发，而后四种算法的提出联合使用了实测浮标数据，与实际情况更加接近。
英文摘要：
Several inversion methods for wave periods based on ahimetric data were described in the paper. The wave periods derived from with the methods were checked using ERA-40 models. The results show that the ac-curacy with CS method is the lowest, the accuracy with CSG2 is the highest, and the accuracy with the other three methods（ CSG1, Hwang and ZT）are similar to each others. Improvement of the accuracy with the latter four meth-ods is due to use of the buoy measured data.
