附:參數(shù)列表
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)
