It follows from Eq. 1.9.5 that at X1 < rL <X2 the particles are effectively scattered by the inhomogeneities whose sizes are of the order of Larmor radius. In the general case, however, at an arbitrary dependence of l and h on X this may be not the fact. Indeed, let it be assumed that the space contains only three basic scales of inhomogeneities Xb X2, X3 and the intensities of their magnetic fields and the distance between them are the following functions of the size of the inhomogeneities:

It follows from Eq. 1.9.6 that rL (X) = rL2 (XXX )~P; rL2 = rL (X )= cp/Zeh2; l = L (Xk /Xj (1.9.6a) where k = 1, 2, 3. Since the times between collisions are the additive values, then

where, according to Eq. 1.9.4 Ak = ¡A-4("Ik +aA )is the transport path i inhomogeneities of the scale Ak (k = 1, 2, 3). From this,
