It is first found that there is an important difference in order-disorder of crystalline structure between the artificial pitchblende and natural pitchblende. Unlike natural pitchblende in which uraninite nanocrystals arrange in order, the artificial pitchblende only contains disorderly uraninite nanocrystals.

在国内、外首次发现此类人工合成沥青铀矿和天然沥青铀矿在晶体结构的有序—无序上存在重大差异：天然沥青铀矿中的纳米级晶质铀矿为有序排列，而人工合成沥青铀矿中的纳米级晶质铀矿则为无序排列。

Marie:When the uranium and thorium are in the pitchblende,the reading is eight, but individually they only total four. Why,then, do they give out twice as much when they're in the pitchblende as they do when they're tested separately?

玛丽：当铀和钍包含在铀矿里的时候，读数是八，而分别测量后加起来只有四，那麼为什麼存在於铀矿中所产生的能量竟是单独产生能量之和的两倍？

The ore minerals consist mainly of pitchblende UO(superscript x, x=2.16~2.70. The pitchblende is mainly intergrown intimately with diagenetic minerals, parts of which is intergrown with authigenic kaolinite, while another parts of which is intergrown or juxtaposed with pyrite of ore-stage, indicating simultaneous precipitation.

镜下观察结果显示，铀矿物主要为沥青铀矿UO(下标 x， x=2.16~2.70，部分与自生高岭石共生，部分则紧密地与矿化阶段黄铁矿共生或交互生长，表明同时沉淀。

pitchblende：沥青铀矿

居礼夫人测量了沥青铀矿(pitchblende)的放射性,沥青铀矿含有75%的氧化铀(UO2),放射强度却是氧化铀的四倍,因此她推测矿物中应该另外存在比纯铀更活泼的物质,后来便是由沥青铀矿中提炼出钋(polonium,Po,以居礼夫人的故乡波兰命名)与镭(radium,
