深海探测溶解无机碳含量异常，可以为寻找热液口提供一个很好的证据。本文设计的基于自制的聚二甲基硅氧烷胶与Zn-Al型水滑石复合膜为离子载体的溶解无机碳探测电极属于电势型电极，适用于对深海中溶解无机碳的测量，具有体积微小、便于与pH、盐度、温度、氧化还原电位等多种传感器集成在同一探头腔内，实施在线探测等优点。实验室条件下，将该溶解无机碳探测电极与银/氯化银参比电极分别接在Keithley 6517A高...
Zinc availability and alkaline phosphatase activity in Emiliania huxleyi: Implications for Zn–P co-limitation in the ocean
Zinc availability alkaline phosphatase activity
2014/4/23
Zinc (Zn) serves as a cofactor in several extracellular phosphatases, which allow microorganisms to acquire
phosphorus from organic P compounds. In oligotrophic ocean water, where both phosphate and ...
Biological factors regulating the chemical speciation of Cu, Zn, and Mn under different nutrient regimes in a marine mesocosm experiment
Biological factors regulating chemical speciation Cu Zn Mn different nutrient regimes marine mesocosm
