摘要：

We present measurements of the voltage-current characteristics of high quality epitaxial YBaCuO films in zero magnetic field. According to the predictions of a current induced vortex pair breaking picture the voltage should follow the functional form V is proportional to I(I - I(c))a-1. An analysis designed to test this functional behavior is carried out. Consistency is found.
