Abstract

The deficiency of traditional variational calculation for the ground-state energy of $\100dpi \inline $H^{+}_{2}$\\$ is found and the reason is revealed，which is beneficial for better understanding the principle of variational method.

Key words： hydrogen molecular ion; variational method; variable substitution
