摘要：

We investigate Brans-Dicke cosmology with perfect-fluid matter and give a method for selecting exact solutions parametrized hy the constant gamma of the state equation p = (gamma - 1)rho and the parameter xi of the nonminimal coupling in which the Brans-Dicke theory can be recast. In this sense, we can classify the solutions having and not having inflationary behavior in the presence of ordinary matter.
