Abstract：In this paper we investigate a model of one-dimensional isentropic bipolar hydrodynamical on the quarter plane ,which takes the form of Euler-Poisson with electric field and frictional damping added to the momentum equation.By using the classical energy method,we will prove the existence of classical solutions.

1 Introduction
Let us consider the following model of one-dimensional isentropic bipolar hydrodynamical. It takes the forms of compressible Euler-Poisson system with frictional damping, on the quarter plane given by
