Standard guide for placement and use of diffusion controlled passive monitors for gaseous pollutants in indoor air 室内空气中气态污染物用扩散控制无源检测器安置和使用的标准指南
According to the i - t curves of potential step , it was revealed that electrocrystallization of ni - w - b alloy on glassy carbon followed the mechanism of instantaneous nucleation and three dimensional growth with diffusion controlled . the crystal nucleus number on the surface of electrode raised by the increase of over potential 根据电位阶跃的i t曲线分析得知,在玻摘要碳电极上ni wb合金电结晶过程遵从扩散控制瞬时成核三维成长模式进行,且随着过电位的增加,电极表面上晶核数增多。
