Abstract: The Delta-perturbation expansion method, a kind of new perturbation technique depending upon an artificial parameter Delta was studied. The study reveals that the method exits some advantages, but also exits some limitations. To overcome the limitations, the so-called linearized perturbation method proposed by HE Ji-huan can be powerfully applied.
