Abstract：
We propose the precise measurement of energy spectra of cascade π and ρ inprocesses e⁺e^-→τ⁺τ^-→e⁺π^-（p^-,μ^-）+ neutrinos in order to determine parity-violatingeffects due to the interference between the electromagnetic and weak neutral currentinteractions.These observations are feasible especially at heavy narrow resonances.Empirically we conjecture that the next quarkonium may be at 28—31 GeV.
