通过对15个铀矿床的铀品位数据进行数理统计,并绘制品位分布直方图和品位分布密度曲线;然后,分别用对数概率纸、偏度峰度和X2三种方法进行检验,都得出一致结论即我国铀矿床品位呈对数正态分布.这一分布规律的认识,为我们进行"品位-储量"估值和铀矿床成矿特点研究提供了有利条件.

Based on mathematic statistics of data about uranium content of 15 uranium ore deposits,the histograms and curves about uranium content distribution were charted.The analysis and research of these histograms and curves arrive at a conclusion that the uranium content of Chinese uranium ore deposit demonstrates log and normal distribution.The knowledge of this distribution regularity facilitates the 'grade reserve'assessment and the resear...
