Abstract
The purpose of this Comment is to point out that the recently publishe d variational estimate of Yu and Gu [Phys. Lett. A 193 (1994) 311; 205 (1995) 295] is indeed an upper bound that can be systematically impro ved and to clarify a claim in a recently published Letter by Gao and L i [Phys. Lett. A 222 (1996) 207].
