A highly sensitive chromatographic system is desirable particularly for monitoring analyte present in trace concentrations within samples
高靈敏的層析系統是一個理想的系統，特別對監測存在於樣本追蹤濃度的分析物。 -
For a given ph condition, adsorption of trace metals on to sediments in the changjiang estuary can be described by the langmuir equation, and implies that increase in trace metal concentrations at natural waters has limited effect on trace metal partitioning coefficients because of high turbidity. 5
在某一給定ph條件下，長江口懸浮泥沙對5種金屬的吸附符合朗格謬爾關系，這表明，在高渾濁度天然水體中微量金屬濃度的變化對它們在固-液兩相之間的分配系數影響不大。 -
The experimental results illustrate that " particle - concentration effects " for trace metals reported in literature are mainly due to the particle dynamics in the estuary. 4. the adsorption percentage ratios of adsorptions and partitioning coefficients for trace metals in the changjiang estuary decease significantly with higher concentrations of elements
這一模擬研究結果說明，通常文獻報道的在河口混合區某些情況下的微量金屬固-液分配的所謂「顆粒物濃度效應」主要與河口現場泥沙顆粒的物理動力學過程有關。 -
