${\mathrm{\η}}_s^{MN}={\mathrm{\ΔV}}_2^{MN}/{\mathrm{\ΔV}}_z^{MN}=({\mathrm{\ΔV}}_z^{MN}-{\mathrm{\ΔV}}_1^{MN})/{\mathrm{\ΔV}}_z^{MN}$

K=2 π r_AM·r_AN/(r_AN-r_AM)

ΔV₁ ^MN=V₁ ^M-V₁ ^N

Wherein, k is electrode coefficient, Δ V₁ ^MN, Δ V₂ ^MN, Δ V_z ^MNIt is respectively on the first test electrode and the second test electrode Primary field, secondary field and potential difference of total field.
