Abstract
Based on a modified version of the global color symmetry model, the pion su sceptibilities of vacuum needed in the QCD sum rule external-field method f or the coupling of pseudoscalar current to hadron have bean calculated beyo nd the vacuum saturation approximation. Comparison with the previous estima tions has been given.
