摘要：

We discuss the temporal variation of the equation of state of a classical string network, evolving in a background in which the Hubble radius H-1 changes with time. We also discribe a method to look for self-consistent non-vacuum string backgrounds, corresponding to the simultaneous solution of the gravi-dilaton background equations and of the string equations of motion.
