| 英文摘要 | In this paper, inspired by the investigations on the theory of cosmological perturbations in horava-lifshitz cosmology, we calculate the spectrum of primordial perturbation lead by a modified dispersion relation in proper time omega(pro) similar to k(z)/a(p) in power-law expansion/ contraction background a similar to t(n) . z is the critical exponent and p is not necessarily equal to z . p = z is well-motivated by horava-lifshitz gravity, and the cases with p not equal z are generalizations beyond the scope. we discuss that for fixed z, if the spectrum is required to be scale-invariant, how should p depend on n. we conclude that there is always room for parameters for the generation of scale-invariant spectrum. |
