In this work, the time effects and superconductivity in the process of phase transition in InSb films condensed at low temperatures are studied. The following important experimental results are obtained: (a) Between occurrence of the first and the second conductance jump, the film samples are in the same amorphous metallic state, and have the same superconducting transition temperature Tc. (b) The relationship between Tc and annealing temperature ta is very similar to that between conductivit σ and Ta. (c) After the second jump, the conductance decreases, during the process of super conducting transition in certain transition zone R(T), the samples transform gradually from perfect to partially superconducting, (d) There are obvious time effects in the process of phase transition.
