In a fully ionized plasma, this phenomenon is proportional to ion velocity times the square of the Larmor radius, which produces a one-half-power dependence on electron temperature. The KPP equation is a one-dimensional form of a system in which this phenomenon is represented by a diagonal matrix multiplying a Laplacian (-5[1])term (10[1])that is paired with a local reaction term. A term representing this phenomenon (10[2])is added to an advective flux (10[1])term in an equation (10[1])named for drift and this phenomenon. (10[3])This phenomenon’s (10[1])coefficient (10[1])is (10[1])proportional to (10[1])temperature (10[2])and mobility, (10[2])as (10[1])identified (10[2])by Einstein. (10[4])The flux (10[3])of this phenomenon is proportional (10[2]-5[1])to a (-5[1])concentration gradient by Fick’s laws. (10[10]-5[1])For 10 points, (10[2])name this phenomenon (10[3])in which particles move from high (10[2])to (10[1])low (10[1])concentrations. (10[2]-5[1])■END■ (10[7]0[2])
