摘要：

The supersymmetric WKB (SUSY-WKB) approximation has been shown to be exact for wide classes of solvable potentials. This has led to folklore that SUSY-WKB is (i) exact for all exactly solvable potentials, and (ii) is never worse than the ordinary WKB approximation for these potentials. We emphasize that both statements are false. © 1990.
