uranium-free 解釋
不含鈾的
  • uranium : n. 【化學】鈾 (U)。 fertile uranium 鈾238。
  • free : adj (freer; freest)1 自由的,自主的;自立的。 a free action 自由行動。 free competition 自由競...
  1. 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。
  2. We consider the reaction product of treated uranium surface is mainly composed of uo2, uc ( or ucxoy ) and free carbon. it may be the mainly reason for surface layer containing uc ( or ucxoy ) to improve corrosion resistance. at the same time the change of gibbs free energies of reaction product of supercritical carbon dioxide with uranium has been computed

    通過aes分析知co _ 2長時間處理金屬鈾后其表面膜層中確實引入了一定量的碳,同時對高碳鈾和低碳鈾抗腐蝕性能的對比可說明金屬鈾表面膜層中碳的存在形式對鈾試樣抗腐蝕性能有很大的影響。
