請問FED這個公式的用法與意義在哪裡(以火災學角度)

FED(max)=Kt/2.303*δm*Sc*LCt50

FED(max)=maximum fractional effective dose,dimensionless

K=proportionality contact

t=exposure time,min

δm=mass optical density, (ft*ft)/lb,(m*m/g)

Sc=visibility criterion,ft(m)

LCt50=lethal exposure dose from test data,(lb/(ft*ft*ft))*min,((g/m*m*m)*min)

請幫忙解釋一下

謝謝
