查询词典 uranium ore

Results showed that the amount of tritium residual in the glass uranium was 2.68%, namely there was (0.0308±0.0003) mmol tritium per gram uranium. The standard deviation of PVT measurement method based on the state equation of the ideal gas was less than 0.95%, when the pressure was between 1500 and 133332 Pa.

直接测量法测量铀床的氚残留量的结果如下：铀床的氚残留量为2.68%，即每克铀含(0.0308±0.0003) mmol 氚气；当压力读数在1500～133332 Pa之间时，基于理想气体状态方程的测量方法的标准差小于0.95%。

Authors suggest that uranium ore formation occurred after the appearance of the above subsidiary tectonic units, and sandstone bodies of the Ⅱ,Ⅲ,Ⅳ,Ⅶ cycles, Shuixigou Group in the southern syncline, and sandstone bodies of the Ⅰ,Ⅱ,Ⅲ,Ⅴ cycles, Shuixigou Group, as well as sandstone bodies of Xiaoquangou Group in the northern monoclinal zone, they are ...

文章认为铀成矿作用发生在这些次级构造单元形成之后，且具有找矿前景的是南部向斜带水西沟群第Ⅱ、Ⅲ、Ⅴ、Ⅶ旋回砂体和北部单斜带水西沟群第Ⅰ、Ⅱ、Ⅲ、Ⅴ旋回砂体及小泉沟群砂体。从容矿层位连续性、分布面积、砂体特征及层间氧化带发育特征等成矿条件看，北部单斜带铀成矿条件和找矿前景均优于南部向斜带。
