Abstract (EN): Page 7673. The general equation that describes the kinetics of chemical order-disorder transitions (section 5.2, eq 2)1,2(Formula present) contains the quantity of dF/d?, that is, the functional derivative of the free energy F on the nonconserved order parameter ?, which is a function of spatial coordinates r. Here, the quantity of F is not a local free energy, as indicated in the comments to eq 2, but the total free energy of the system, which can be written as a free-energy functional2(Formula present) where f 0(?) is the free energy per unit volume of a uniform system and K2 is the first term of an expansion representing the increase in free energy due to introducing a gradient of . However, this misunderstanding did not affect the transition to a discrete approximation3,4 that we use to account for the relaxation rates of chemical ordering/ disordering in the system of interest.
