uranium carbide meaning in English

碳化铀

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
当温度高于573k时，温度增强了铀及其合金表面上的氧的解吸和向体内扩散，以及促使体内的碳向表面上偏析，导致在铀及其合金表面上形成了铀碳化合物，并在体内出现富二氧化铀层，随着温度的升高，表面上的氧和铀原子的比值降低，铀碳化合物含量增加，体内的富二氧化铀层加厚。
