We choose the typical metallic glass Cu1-xTix alloys with two concent ations (x= 0.300 and x=0.325) made by melt-spinning technique as the sample. The X-ray diffraction, DTA and DSC analyses show that the samples exhibit typical amorphous charac-teristecs. In the wide temperature range 2-700 K, the resistivity is in aceordance with Mooij rule. Based on the Nagel nearly free electron model, Mott s-d scattering model, quasi-particles excitation by disorder configuration model and two-level tunnelling model for the electrical transport properties of amorphous alloys, the results are analysed,. The theoretical results in two level tunnelling model agree with the experimental data much better.
