  We divide the free energy near the critical point into two parts. One is the
regular part, the other is the singular part. The singular part is assumed to
be a concrete possible form. The singular part in this form is different from
Widom scaling hypothesis and can give out the scaling laws of the critical
exponents about the thermodynamic quantities. Furthermore, the critical
exponents will be right worked out. We proof the singular part in this form can
satisfy the qualities of the scaling function mentioned out by Widom. As an
assumption, we expect the free energy in this form will be significative for
the future research. Note: If you have any suggestions when this paper is
considered, connect us with<EMAIL_ADDRESS>please.:)
