| 摘 要： | Introduction Inflation cosmology is an important theory fordescribing the evolution of the early universe. Thistheory attracts wide attention1-3]because it can suc-cessfully explain the flatness, horizon and magnticmonopole problems, and may be supported experi-mently in observation of microwave background radia-tion. There are two basic types of inflation models:one is the higher-derivative gravity model; another isbased on the model of scalar field. These models areusually studied within th…

| Abstract: | The purpose of this paper is to study cosmological properties of two-dimensional Brans-Dicke gravity model. For massless scalar field, the new cosmological solutions are found by integration of field equation, these solutions correspond to the inflation solutions with positive cosmological constant. The result of this paper show that the inflation process of universe is controlled by the classical and quantum effect of the scalar field. |
