摘要：
The improved Hill determinant method with a variational parameter is applied to the general polynomial quantum anharmonic-oscillator and multiwell-oscillator problems. We calculate the eigenvalues and the expectation values < x2m > of the oscillator, which are in good agreement with the exact values obtained by using supersymmetric quantum mechanics.
