摘　　要：采用直线加速器中的有限圆柱空间电荷模型，推导得出了电荷束团的纵向密度分布为水袋型和抛物线型与横向密度分布为均匀（Ｋ－Ｖ）型、水袋型、抛物线型及高斯型等各种组合非均匀密度分布的空间电荷场公式，藉以考察束团的非线性空间电荷效应。The nonlinear space charge effect of bunched beam with nonuniform density distributions inboth longitudinal and transverse directions is discussed in the paper. Some useful formulae are de-rived for calculating the potential induced by a cylinder model of space charge in the waveguide ofa linac with longitudinal density distributions of waterbag( WB) or parabolic(PA) type combiningwith transverse density distributions of Kapchinskij-Vladimirskij( K-V), waterbag, parabolic andGaussian (GA) types, respectively.
