Measurements of magnetoresistance of upper critical magnetic field have been made on superconducting metallic glass Zr78Co22. The results correspond qualitatively with the weak localization theory including spin-orbit scattering for three demensional system. Quantitatively, there exists an obvious deviation, which originates mainly from superconducting fluctuations. In the measuring temperature range, the value of upper critical field Mc2 varies linearly with temperature, and we obtain the inelastic scattering rate τi-1=1.3×1O10T2, which can be atributed to the electron-phonon processes in disordered metals This value is slightly lower than that predicted by Bergmann theory.
