最近返回来的稿件中提到了这个问题，请教一下做电化学的各位们：“The abstract states that there is a four electron transition step in oxygen reduction, however, the offset of slope to the electron number is about 0.5 – 0.8. Hence, it seems like a systematic error in the experiment and should be calibrated by using the results of Pt electrode in the same characterizations.”
为什么是系统错误？怎么矫正？
