附：ojip參數(shù)及計(jì)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)
