摘要：

We show how to relate the moments of the reconstructed hadronic invariant mass distribution to the moments of the physical spectrum in a model independent way. The only information needed on detector resolution functions is their first few moments. Theoretical predictions for the first three moments as functions of nonperturbative parameters are given for various lepton energy cuts.
