摘要：
We present a class of exact cosmological solutions of Brans-Dicke (B-D) equations with cosmological constant in flat Robertson-Walker metric. These solutions are based on the relation phi R(n) = constant between the B-D field and the scale factor of the universe. This relation turns out to be consistent with the equation of state p = m rho for the cosmic matter, provided that n and m are suitably related to each other. Several special cases and asymptotic solutions are derived and discussed.
