Abstract:
To make out a Taper Faced Equation（TFE） while known the vertex and directrix of the taper, by transforming the directrix equation to another form in which has such factors as （x-a）, （y-b）, （z-c）, we try to get an equal power equation, then rectify it to be the TFE.[著者文摘]
Key words:
taper faced; equal power equation; directrix generatrix
