摘要：

An alternative to the standard cold dark matter model has been recently proposed in which a significant fraction of the energy density of the universe is due to a dynamical scalar field (Q) whose effective equation of state differs from that of matter, radiation or cosmological constant (A). In this paper, we determine how the Q component modifies the primordial inflation gravitational wave (tensor metric) contribution to the cosmic microwave background anisotropy and, thereby, one of the key tests of inflation.
