摘要：

We present a detailed investigation of the renormalization scheme dependence of the next-to-next-to-leading order QCD predictions for the processes e+e- --> hadrons and tau --> v-tau+ hadrons. Based on it the comparison of the results obtained in three frequently used approaches to resolving the renormalization scheme ambiguities with experimental data is carried out.
