盐度梯度 meaning in English
salinity gradient
Examples
- The major ions changjiang show characteristics of hco3 > c1 " + so42 ~ for anions and ca2 + > mg2 + + na + + k + for cations independent of variations of sediment concentration and ph
在河口盐度梯度上，主要阳离子浓度可以用长江河水与口外海水的线性混合所预测。 - The results show that cu and zn tend to be quasi - conservative , whereas cd , co and ni are remobilized over a broad salinity range in the changjiang estuary
和ni在长江口盐度梯度上固一液相态变化，并将模型输出结果与长江口几种金属的历史观测资料进行了对比。 - Influences of the inclined pressure item caused by salinity - gradient on the flow and those of the deepening of the channel on the invasion of salt water are analyzed by use of a three - dimensional salinity mathematical model for the north channel of the yangtze river estuary
利用长江口北槽三维水流盐度数学模型分析了盐度梯度引起的斜压项对水流的影响，以及航道增深对盐水入侵的影响。 - Both species grew poorly in the culture medium absent of salt , especially to a . corniculatum . moderate salt stress ( from 5 to 20 ) can stimulate the growth of both species , and the optimum salinity for growth was from 10 to 15 . when the substrate salinity was higher than 30 , stem height , root length , dry mass increment , net photosynthetic rate fell remarkably for both species
温室内人工盐度梯度栽培下，木榄幼苗地上、地下部分形态和生物量的增长均表现为低盐促进和高盐抑制，以10 15盐度下最适合木榄幼苗的生长；盐度从10增加到50时，木榄幼苗的净光合速率、气孔导度和蒸腾速率均随之下降。 - Length , diameter , density , fresh weight , dry weight , water content , osmotic potential and element concentrations ( ca , mg , na , k , cl ) were determined for each . seedling of b . gymnorrhiza and a . corniculatum were cultured for 60 days on various salinity of seawater ( 0 , 5 , 10 , 15 , 20 , 30 , 40 , 50 ) in green house . samples were taken at 3 , 7 , 11 , 15 , 22 , 30 , 45 and 60 days after planting , separated into root , hypocotyl , stem and leaf
