Abstract：
In this paper,using a cylinder model of space charge,the formulae of self-energy and emittance growth for a bunched beam with Gaussian type density distribution in both longitudinal and transverse directions in linac are derived.And the scaling law relating the beam parameters with the machine parameters are discussed by means of the numerical simulation results.
