abstract = {A second-order differential equation is derived for the electric potential of an electron system with slowly varying density. It includes consistently the first-gradient corrections to both the kinetic energy and the exchange energy. In the regime of high density, the equation reduces to the one derived by Schwinger Phys. Rev. A 24 2353 (1981)},
