Because the effects of atmospheric carbon take years to show up as higher temperatures, limitingconcentration to 450 ppm requires halting emissions at current levels.
The relations between voltage and oxygen concentration of limiting current were investigated by dynamic scan, respectively.
借助动态电位扫描分别研究了电流与施加电压的关系，极限电流与氧浓度的关系。

The minimum magnetic field intensity needed to induce significant effect on cathodic limiting diffusion current density decreased with increasing ferric ion concentration.
