摘要：
We perform the phase space analysis in terms of the linearization technique in the Horava-Lifshitz gravity with the softly broken detailed balance condition. It can be shown that the bouncing universe appears only for the positive spatial curvature of k = +1, and it is possible to obtain oscillating universe with the help of the negative dark radiation and the negative cosmological constant.
