Standard guide for placement and use of diffusion controlled passive monitors for gaseous pollutants in indoor air 室內空氣中氣態(tài)污染物用擴散控制無源檢測器安置和使用的標準指南
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 根據電位階躍的i t曲線分析得知,在玻摘要碳電極上ni wb合金電結晶過程遵從擴散控制瞬時成核三維成長模式進行,且隨著過電位的增加,電極表面上晶核數增多。
