We study reaction zones in three different versions of the A+B->0 system. Fora steady state formed by opposing currents of A and B particles we derivescaling behavior via renormalization group analysis. By use of a previouslydeveloped analogy, these results are extended to the time-dependent case of aninitially segregated system. We also consider an initially mixed system, whichforms reaction zones for dimension d<4. In this case an extension of thesteady-state analogy gives scaling results characterized by new exponents.Comment: 4 pages, REVTeX 3.0 with epsf, 2 uuencoded postscript figures  appended, OUTP-94-33
