Three new observables for Z-factory to measure the weak dipole moment of$\tau$ lepton ($d_w^\tau$) are proposed. As those observables employed atLEP-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 thedependence, precisely and find that the obtained slopes are much lager thanthose 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 ordoing the measurement at a possible Z-factory in the near future.

Suggestion for measuring the weak dipole moment of $\tau$ lepton at Z-factory
