摘要：

The perturbative QCD corrections to the semileptonic decay width of the tau lepton are analyzed in various renormalization schemes. Significant differences are found between a priori admissible schemes, which indicates that it is impossible to use these corrections to obtain a precise determination of the QCD scale parameter LAMBDA.
