摘要：

This letter investigates the time-machine problem in perfect fluid cosmologies. It solves the Einstein's field equations with the energy-momentum tensors for perfect fluid and constructs a class of time-machine solutions, by which the time-machine problem in the perfect fluid cosmologies is solved.
