摘要：
We present an explicit procedure for obtaining the equation of motion for the Wigner distribution when the underlying governing equation is a linear ordinary or partial differential equation. The cases of constant and variable coefficients are considered. (C) 2002 Elsevier Science B.V. All rights reserved.
