摘　　要：根据涡动混合张量,计算涡动交换张量分量,进而利用普郎特公式计算混合长度,并采用混合交换椭球方程导出混合交换椭圆方程。以此计算本区涡动交换混合椭圆要素的分布,阐明台湾海峡西部涡动混合的变化规律。得出海峡西部涡动混合的变化与流势的分布变化规律较一致,即流速大的涡动混合交换强,顺流方向或平行于岸线的涡动混合强于横截于流或垂直岸线的涡动混合,其混合强度冬季比夏季强,表层比底层强,南部比北部强。The eddy exchange tensor components were calculated with the eddy mixed tensor theory and the eddy mixture length was calculated with Prandt's Formula. The eddy exchange elliptic equation was derived from the mixtrue exchange ellipsoid equation and applied to calculating the elements of mixture exchange ellipse and illustrating the variation pattern of eddy mixture in the western part of the Taiwan Strait. It was found that the distributional pattern in the deeddy mixture was agreeable with that in the current field of the waters.
