求助This was explained by assuming that, in the presence of the polymer film, stripping of the metals was thermodynamically more reversible as the oxidized metal species were retained close to the electrode surface by the negatively charged sulfonic groups of the Nafion film, so that the effects of diffusion were reduced. 翻译 |

This was explained by assuming that, in the presence of the polymer film, stripping of the metals was thermodynamically more reversible as the oxidized metal species were retained close to the electrode surface by the negatively charged sulfonic groups of the Nafion film, so that the effects of diffusion were reduced. 这可以这样解释：假设有聚合物薄膜保护着，金属剥脱的热力学过程就变得可逆，因为界面上金属的氧化层被全氟磺酸薄膜中带负电的磺酸基团限制住，所以扩散效应也就降低了。 |
