  The O3 concentration has close relationship with the solar radiation intensity and reaches to the maximum at 14:00 almost and decreases on night for the deoxidization reaction on each layer.

  O3浓度与太阳辐射强度关系密切,各层均在正午14时前后达到最大,而夜间的还原反应使各层臭氧浓度下降。

能源科学技术

• 脱氧

  The effect of Re element addition on the nitrogen content in the weld was insignificant due to the oxidization from the early deoxidization stage.

  而由于稀土元素在先期脱氧中大量氧化，其脱氮效果较弱，稀土元素对熔敷金属的总含氮量的影响不显著。

• 还原

  The electrochemical performance tests indicated that dynamic performances of alloy electrodes were relatively preferable and the oxidation and deoxidization of hydrogen dominated electrode reaction.

  电化学性能测试表明,合金电极的动力学性能较好,氢的氧化还原反应控制着电极反应。
