uranium carbide 中文意思是什麼

uranium carbide 解釋
碳化鈾
  • uranium : n. 【化學】鈾 （U）。 fertile uranium 鈾238。
  • carbide : n. 【化學】碳化物；碳化鈣；電石〈粗製CaC2〉。
  1. 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。
  2. The investigation indicates the electrochemical corrosion resistance characteristic of uranium surface has also been enhanced. the corrosion resistance of uranium with high carbon content may be lower than that of uranium with low carbon content. therefore we consider the carbon format ( carbide or free carbon ) may be the mainly reason of improving corrosion resistance

    採用電化學方法，我們得到了表面經超臨界co _ 2處理的鈾試樣在50 g / gcl ~ -中的陽極極化曲線和自腐蝕電流等抗蝕評價指標，結果表明經超臨界co _ 2處理后的鈾樣品其抗化學介質腐蝕性能也有一定的提高。
  3. 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。
