salinity gradient造句

• Through salinity gradient , the major cations levels can be predicted with a linear mixing model . 2 . simulation results show that ph variation within the changjiang estuary has significant effect on solid - liquid partitioning of trace metals
  模拟结果表明，长江口微量金属固-液分配的ph效应显著， ph的升高增大了微量金属在泥沙中的分配，并可促使微量金属元素向泥沙固相中转移。
• Based on solid - liquid interface ion exchange model , using in - situ data of ph , sediment concentration , trace metal and salinity in the changjiang estuary , solid - liquid phase transformation for metals cu , zn , cd , co , ni through salinity gradient was calculated , and the modeling results was compared with in - situ data sets reported in literature
  华东师范大学博士学位论文摘要6 .在固一液界面离子交换模型的基础上，以长江口现场调查得到的ph 、悬浮泥沙浓度、金属浓度和盐度作为模型的输入量探讨了cu 、 zn 、 cd 、 c 。
