英文摘要: We propose and investigate a general form of the dissipative coefficient Gamma = C(phi)T(m)/phi(m-1) in warm inflation. We focus on discussing the strong dissipative processes r = Gamma/3H >> 1 in the thermal state of approximate equilibrium. To this toy model, we give the slow-roll conditions, the amplitude and the index of the power spectrum under the general form of dissipative coefficient. Furthermore, the monomial potential and the hybrid-like potential are analyzed specifically. We conclude that the m = 0, 3 cases are worthy further investigation especially.
