NLO calculations of the three-jet heavy quark production in   e^+e^--annihilation: status and applications
  Next-to-leading order calculations for heavy quark three-jet production in e+e- annihilation are reviewed. Their applications for the measurement of the b-quark mass at LEP/SLC and for the test of flavour independence of the strong coupling constant are discussed.
