长江中下游地下水中Cr、V、Co的形成及分布规律

REGULARITES GOVERNING THE FORMATION AND DISTRIBUTION OF Cr、V AND CO IN GROUND WATER IN THE MIDDIE AND LOWER BASINS OF THE YANGTZE RIVER

以丰富的实际资料，论证了地下水中Ｃｒ、Ｖ、Ｃｏ元素的形成、含量及其分布规律，除了与地下水的含水介质成分有关外，主要受酸碱度和氧化还原环境的控制。

With plentiful actual materias the regularities governing the formation,content, anddistribution of Cr、V and Co in ground water are brought forward in this articLe. Controllingfactors include acidity and alkalinity, oxidation and reduction environment in addition to thecomposition of the aquiferous medium of ground water.
