摘　　要：　描述了一种由对称的均匀场和非均匀场构成的复合场消色差２７０°磁偏转系统；用矩阵方法导出了系统的消色差关系式．系统具有良好的消色差和聚焦特性，输出的电子束不仅束斑小且具有包络和发散角双重对称性，适合於低能电子直线加速器高质量的束流输运。A combinatory field achromatic 270°deflection system is described.A uniform field is combined with a nonuniform one in a symmetric magnet. Design of the system is based on the achromatic relation derived with the matrix method. Electron beam at the output is small in spot and symmetric with respect both to envelope and to divergent angle,indicating that the system possesses excellent achromatic and focusing properties.
