铀被水的迁移强度是该元素重要的地球化学特征。认识了这一特征,就可以比较铀与共它元素的迁移能力,并确定它在地球化学分类中占的位置。不难看出,仅是根据水中铀含量的资料还不能得出关于铀的水迁移强度的清楚概念。例如在许多天然水中铀含量为5×10~(-6)克/升,而硅含 The migration of uranium by water is an important geochemical feature of this element. Recognizing this trait, one can compare the mobility of uranium with its total elements and determine its place in the geochemical classification. It is not hard to see that a clear concept of water transfer intensity of uranium can not be derived from mere data based on uranium content in water. For example, in many natural waters uranium content of 5 × 10 ~ (-6) g / L, and silicon
