摘要：

We reanalyse the pionic form factor by using perturbative QCD theory and contributions from end-point regions. We find that the perturbative QCD can be applied to the pionic form factor as Q2 > 4 GeV2 and they become unreliable as Q2 less-than-or-equal-to 4 GeV2. Therefore the applicability of perturbative QCD to the form factor is questionable only as Q2 less-than-or-equal-to 4 GeV2.
