此外， 还考察了甲烷化反应的速控步骤， 及因解离物种可能在表面上的沉积使表面有所改性， 从而影响CO甲烷化表面反应的活性。

Also, we investigate the rate-determining-step of methanation reaction on those surfaces, and the influences of the deposited surface species at reaction beginning on the reactivity of CO methanation.

发现随着电解质体系粘度的增加，I_3~-离子扩散系数急剧下降，进而在准固念染料敏化太阳能电池的光电转换过程中形成新的速控步骤I_3~-离子的扩散过程。

With the increasing of the viscosity of electrolyte, the diffusion coefficient of I_3 ion decreased rapidly to be a new controlling step in the quasi-solid state dye-sensitized solar cell.
