Query: Suggestion for measuring the weak dipole moment of $\tau$ lepton at
  Z-factory   Three new observables for Z-factory to measure the weak dipole moment of
$\tau$ lepton ($d_w^\tau$) are proposed. As those observables employed at
LEP-I, the new observables depend on the real and imaginary parts of $d_w^\tau$
linearly, thus we calculate the slopes, i.e. the linear coefficients of the
dependence, precisely and find that the obtained slopes are much lager than
those employed at LEP-I. It means that the signal for the weak dipole moment
$d_w^\tau$ may be enhanced quite a lot, if one employs the new observables.
Being superior to those at LEP-I, we recommend measuring the weak dipole moment
$d_w^\tau$ in terms of the new observables if re-analyzing the data of LEP-I or
doing the measurement at a possible Z-factory in the near future.
