Query: Reply to Comment on "Theory of Spinodal Decomposition"   Rutenberg [cond-mat/9411016] claimed erroneously that I incorrectly apply
only global conservation constraint to systems with local conservation embodied
by continuity equation [PRL vol.72, p.1850 (1994)]. I reply that my theory
describes the order parameter (OP) evolution of all three types of systems:
without conservation law, with global one and with local one. I explain that
continuity equation is a differential form of global conservation law, taking
into account the absence of OP production. It is a supplementary equation, but
it contains an unknown variable - OP flux. In my theory OP flux can be always
found from OP evolution equation and continuity one.
