Abstract
Critical indices , , , etc. are defined and calculated for self-organized critical phenomena. Scaling relations are derived and checked numerically. The order-parameter exponent describes the spontaneous current and the relaxation to the critical point. The power spectrum has "" behavior with exponent , where is the dynamical critical exponent.
