摘要：

We show that the factor ordering ambiguities associated with the loop quantization of the gravitational part of the cosmological Hamiltonian constraint disappear at the level of the Wheeler-DeWitt equation only for a particular choice of lattice refinement model, which coincides with constraints imposed from phenomenological and consistency arguments.
