用法和例句

The concentration of uranium at the redox front of sandstone type U-deposits are commonly interpreted as a result of the reduction of U6+ in ground water to U4+ to form uranium minerals and their precipitation,and reductants of uranium are considered to be carbonized plant debris remained in sandstone and sulphides,of them,particularly the pyrite.

在层间氧化带砂岩型铀矿床中,铀在氧化还原前锋线附近的富集通常被解释为地下水中的U6+被还原为U4+形成铀矿物并沉淀,铀的还原剂则是保存在砂岩中的炭化植物碎屑和硫化物,特别是黄铁矿。
