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.3 pages, Latex, no figures, submitted to Phys. Rev. Lett. 06 July 1995, revised 18 April 1996Condensed Mattertext
