摘要：

We work out an iterative solution of the evolution equations for alpha1, alpha2, alpha3 in the Minimal Supersymmetric SU(5) Grand Unified model with the condition that the gauge couplings should converge smoothly towards E(GUT) and should not separate above E(GUT). The work is done at two levels of theoretical accuracy: one loop and two loops. Improved accuracy favours high values of alpha3(M(Z)) with respect to the world average.
