附：OJIP參數(shù)及計算公式

Bckg = background

Fo = F50μs; fluorescence intensity at 50 μs

Fj = fluorescence intensity at j-step (at 2 ms)

Fi = fluorescence intensity at i-step (at 60 ms)

Fm = maximal fluorescence intensity

Fv = Fm - Fo (maximal variable fluorescence)

Vj = (Fj - Fo) / (Fm - Fo)

Fm / Fo = Fm / Fo

Fv / Fo = Fv / Fo

Fv / Fm = Fv / Fm

Mo = TRo / RC - ETo / RC

Area = area between fluorescence curve and Fm

Sm = area / Fm - Fo (multiple turn-over)

Ss = the smallest Sm turn-over (single turn-over)

N = Sm . Mo . (I / Vj) turn-over number QA

Phi_Po = (I - Fo) / Fm (or Fv / Fm)

Phi_o = I - Vj

Phi_Eo = (I - Fo / Fm) . Phi_o

Phi_Do = 1 - Phi_Po - (Fo / Fm)

Phi_Pav = Phi_Po - (Sm / tFM); tFM = time to reach Fm (in ms)

ABS / RC = Mo . (I / Vj) . (I / Phi_Po)

TRo / RC = Mo . (I / Vj)

ETo / RC = Mo . (I / Vj) . Phi_o)

DIo / RC = (ABS / RC) - (TRo / RC)
