Examples
- The tafel curves of methanol electro - oxidation on tmchnodified pt / ti anode can be divided into three distinct regions
从tafel曲线来看，甲醇的电氧化过程分三个步骤。 - Transport in the diffusion layers and catalyst layers are described by a superposition of knudsen diffusion and stefan - maxwell diffusion , and electrochemical kinetics for anodic methanol oxidation and cathodic oxygen reduction are described by tafel equation
模型以stefan - maxwell扩散和knudsen扩散的叠加描述了气体混合物在多孔电极中的扩散过程，以tafel方程描述了甲醇在阳极氧化和氧在阴极还原的电化学动力学。 - Corrosion action slope cable used in cable - stayed bridge in different corrosion medium such as synthesis sea water , solution nacl and simulation acid rain are studied by electrochemical method , for example , linear polarization , tafel extrapolation and ac impedance method
对此,本论文以人造海水、 nacl溶液、模拟酸雨作为腐蚀介质,针对不同类型的钢绞线,采用线性极化法、 tafel外推法和交流阻抗法等电化学方法研究斜拉桥拉索结构中钢绞线在不同介质中的腐蚀行为。 - The corrosion potential was the biggest and the corrosion current was the smallest one when the concentration of super - 3900 was 0 . 5 % ; the corrosion potential was increased with the addition of mps - dl , but the smallest corrosion current is under 0 . 01 % mps - dl . the rust time was the longest one when the concentration of super - 3900 was 0 . 5 % as well as mps - dl was 0 . 01 % . it was increased as a peak curve with al2o3 concentration in plating solution and ph value increased gradually with cathodic current density ; the corrosion weight
通过测量tafel曲线可知,在super - 3900浓度为0 . 5 % (相对于镀液的体积百分含量)时获得的镀层腐蚀电位最正,腐蚀电流密度最小;随着镀液中mps - dl含量的增加,获得的镀层的腐蚀电位逐渐正移,在浓度为0 . 01 % (相对于镀液的体积百分含量)时腐蚀电流密度最小。 - 6 ) , the process that h20 is adsorbed on the electrode surface and the hydroxyl group is formed to oxidize the co may be the rate - determining step ; in the region iil ( logi > l . 6 ) , all of the tafel curves show a curvature until the current densities reach the peak value , indicative of a possible limiting current . the effect of rare earth elements on methanol electro - oxidation has not been reported in literatures
在低极化区( logi 1 . 3 ) ，甲醇发生脱氢反应并形成反应中间体，其中co成为未被氧化的毒物，此过程成为速率限制步骤；在更高的极化区( 1 . 3 logi 1 . 6 ) ， h _ 2o吸附在电极表面并解离生成[ oh ] ，促进了co的氧化，此为此阶段速率控制步骤：在第3个极化区( 10gi 1 . 6 ) ， tafel曲线发生弯曲，电流密度也最终达到峰值。
