摘要：
A systematic technique based on a variational principle is developed for obtaining WKB Green's functions for a non-Hermitian set of inhomogeneous, nonstationary differential equations in a space of arbitrary dimensions. A key element in this technique involves the use of the Van Vleck determinant for the amplitudes of WKB functions.
