Moreover, the fitting degree of curvilinear regression equation is tested by correlation index, in stead of correlation coefficient which has been unsuitably used for testing in similar works.

此外，用相关指数来检验曲线回归方程的拟合程度，而不采用在类似的研究中用相关系数来检验曲线回归这一不合适的方法。

In view of the lower fitting degree of commonly used K-distribution model for various sea, especially for low sea state cluster, an improved K-distribution model was proposed.

鉴于目前最常用的K分布模型对各种海态下特别是低海态海杂波的统计特性拟合程度不高，提出了改进K分布模型。
