生态水文课题组 《ACS earth and space chemistry》吞吐型湖泊 水—气界面碳交换
2023/1/11
湖泊代谢(metabolism)指湖泊生物不断进行的光合和呼吸作用，可通过湖泊总初级生产力（GPP）和湖泊总呼吸（RE）量化。水体二氧化碳分压（pCO2)指溶解在水中的二氧化碳（CO2）分子产生的压力，可用来量化量溶解在水中的二氧化碳的量。pCO2与其他参数，如 pH 值、溶解性无机碳和碱度一样，都用来描述水体的无机碳系统（CO2 (aq)、HCO3-、CO32-）的浓度和形态。湖泊pCO2不仅受...

CHEMISTRY OF GROUNDWATER IN IGNEOUS ROCK AT ANGERED,GOTHENBURG
CHEMISTRY OF GROUNDWATER IGNEOUS ROCK
2009/10/29
Within an area of about 5 km2, 25 wells were drilled to depths of about
90 m for groundwater observation. The wells were sampled and analyzed,
and from the results it could be concluded that the ion...
Chemical changes in water circulating deep in the fissures of the solid
rock are studied. The ultimate chemical composition is determined by
the conditions of percolation through the soil zone. For ...
