  1. Uranium dioxide pellet - determinaiton of carbon

    二氧化鈾芯塊中碳的測定
  2. According to the analysis on the lithogeochemical features and the carbon and oxygen isotopes of calcareous sandstones, it is realized that there some genetic relation between the formation of calcareous sandstone and uranium mineralization in the oxidation - deoxidation transitional belt, that is the precipitation and enrichment of uranium is accompanied by the deposition of carbonate and formation of calcareous sandstone

    根據鈣質砂巖的巖石地球化學特徵，結合碳、氧同位素分析認為，氧化還原過渡帶中鈣質砂巖的發育與鈾礦化的形成具有一定的成因聯系，即在鈾沉澱富集成礦的同時，伴隨著碳酸鹽的析出作用，形成鈣質砂巖。
  3. Standard test method for carbon in uranium oxide powders and pellets by direct combustion - infrared detection method

    用直接燃燒紅外探測法測定氧化鈾粉末和顆粒中總碳量的標準試驗方法
  4. The low - enriched uranium fuel consists of half - millimetre - sized particles of uranium dioxide encased in graphite and silicon carbide, which in turn is encased in a graphite ball

    低濃縮的鈾燃料為包裹在石墨和碳化硅中半毫米大小的二氧化鈾微粒，石墨和碳化硅則被包裹在石墨球中。
  5. We have carried out th / u dating on intercalated calcite samples. the results show that the capping flowstone layer is of an age of 94 ka, and the second one 220 ka. the fossil - bearing deposits which are bracketed by the two flowstone layers should be of an age between 94 and 220 ka

    新生碳酸鹽巖與骨化石的鈾系測年結果表明：該地點覆蓋含人牙化石堆積的表層鈣板在約94ka以前開始形成，堆積疊壓的鈣板年代為約220ka ，人牙化石的年代應介於兩者之間。
  6. When surface temperatures of uranium and uranium - niobium alloys increase higher than 573k, heating was observed to deplete surface oxygen by accelerating its transport into the bulk and separate carbon out to their surface. so there were uranium carbide formed on the surface and thicker layer of uo _ ( 2 ) formed in the bulk. with surface temperature increasing, the o / u ratio dropped sharply as the surface oxygen diffused into the bulk

    當溫度高於573k時，溫度增強了鈾及其合金表面上的氧的解吸和向體內擴散，以及促使體內的碳向表面上偏析，導致在鈾及其合金表面上形成了鈾碳化合物，並在體內出現富二氧化鈾層，隨著溫度的升高，表面上的氧和鈾原子的比值降低，鈾碳化合物含量增加，體內的富二氧化鈾層加厚。
