摘　　要：应用烯酮化合物的不饱和比值Ｕ，计算得出冲绳海槽海水古温度波动幅度在１５．９～２６．２℃之间，平均为２２．９℃，和冬季实测表层水温２２．０℃相接近，探讨了Ｕ值在冲绳海槽指示的古海水温度和季节有关，主要反映在冬季．he sea surface temperature is estimated by the U value (the unsaturated ratio of alkenone) in sediment from the Okinawa Trough during the last 20 000 a. They range from 15.9 to 26.2℃, the average is 22. 9℃. The sea surface temperature in winter is 22℃. It indicates that the sea surface temperature from U is close to the above value.
