常見例句Generally, in 24 hours, the DOC in euphotic layer is higher in the daytime than that in the night time. 角毛藻分泌的溶解有機碳(DOC)與顆粒有機碳(POC)存在晝夜變化規(guī)律：白天比晚上高，夜晚始終處于低值；This reduced the efficiency of upwelling to cool the suface and cut off the supply of nutrient rich thermocline water to the euphotic zone. 拉尼娜與厄爾尼諾性格相反，隨著厄爾尼諾的消失，拉尼娜的到來，全球許多地區(qū)的天氣與氣候災害也將發(fā)生轉變。This reduced the efficiency of upwelling to cool the suface and cut off the supply of nutrient rich themp3ocline water to the euphotic zone. 拉尼娜與厄爾尼諾性格相反，隨著厄爾尼諾的消失，拉尼娜的到來，全球許多地區(qū)的天氣與氣候災害也將發(fā)生轉變。Contribution of Cph to POC in the upper waters was higher than in the deeper euphotic zone.During the same survey,distribution characteristics of chlorophyll a concentration... 同時分析兩個航次測區(qū)葉綠素a濃度和航程途中葉綠素a濃度的分布,以期了解浮游植物在南大洋顆粒有機碳來源中的作用。The euphotic is the brightly lit upper zone where drifting phytoplankton carry out photosynthesis and are responsible for about 40% of the world's photosyn-thetic activity. 適于綠色植物生長之海水最上層是較上面地帶，漂流的浮游植物在此處進行光合作用，而負責大約全世界40%25光合活動，營養(yǎng)物質的含量水準低。Biological production and consumption of DMS, primarily taking place within the marine euphotic zone, are considered to be the predominate source and sink of DMS in seawater. DMS的生物生產與消耗主要發(fā)生在海洋真光層。 返回 euphotic
