[求助] 电化学阴离子识别中公式电位差ΔE=logK+/v中分母的v代表什么？着急，多谢！

各位，大家好，看综述时候发现
“At this stage, the peak at 500 mV has disappeared. This
behaviour can be interpreted on the basis of the thermodynamic
cycle illustrated in Fig. 29b. In particular, the potential
difference between the peak in the absence and the peak in the
presence of the anion, ΔE = E-EX, at 25 oC, is expressed by
the following equation:
logK+/ν (8)
The larger the peak separation, the higher the stability of the
complex of the oxidised receptor with respect to the reduced
one. The K+/K ratio is defined enhancement factor. If the value
of K has been preliminarily determined through an independent
experiment (e.g. a spectrophotometric or a 1H NMR
titration) the value of K+ can be calculated from eqn (8).”

公式8没看明白分母上的字母代表啥意思？难道是扫速，又不太像。
