thanks for your help 
I've try this method, but doesn't work just as my mind~
in softimage, the translation of an object is according to its center. so if we move the center to 0,0,0, then switch back to object mode, the translation of object is already in 0,0,0. it's no any effect that translate it to 0,0,0 again, so this method doesn't work~
so any other method??
