overlying sediments 中文意思是什麼
-
2. the relationships between the nutrients exchange rates and the potential environmental controls it was observed that the exchange rates of sio3 - si were correlated with the temperature, do, ph, salinity of the seawater, the water and clay contents of the sediments and the concentrations of sio3 - si in the overlying water and pore water of the sediments
2 、影響營養鹽在東海沉積物一海水界面交換速率的主要因素sio _ 3 - si在東海沉積物?海水界面交換速率與水體溫度、 do濃度、 ph值、鹽度、沉積物的含水率、粘土礦物含量、間隙水中sio _ 3 - si濃度、上覆水中sio _ 3 - si濃度均存在很好的相關性。 -
Nh4c and o - p concentrations were 35 and 7 times higher, respectively, in the pore water than in the overlying marsh, suggesting a permanent flux of nutrients from the sediments
孔隙水中的nh4c和o - p濃度比上層濕地水的濃度分別高出35倍和7倍，這表明營養物質穩定地從沉澱物中流出。 -
The results indicated that on average the rank order of the concentrations of different nitrogen species in overlying water and porewater was organic nitrogen > ammonia > nitrate ; the main form of inorganic nitrogen in sediments was of ammonia, and the submerged plant cannot change this case
結果表明：總體上，上覆水和間隙水中不同形態氮含量的順序為有機氮氨氮硝態氮；沉積物中可交換態無機氮以氨氮為主，沉水植物的存在並沒有改變這一格局。
