摘要
详细讨论了多重网法数值求解三维静电场的若干数学问题,诸如三维多重网格法的限制与延拓公式推导、确定静电像管三维电子光学系统中的锥面电极、圆筒电极、球面电极、圆孔膜片电极、孔电极等的空间位置及范围的方法、以及迭代计算的逻辑尺编码方法等,为像管电子光学系统设计及优化设计奠定了良好基础.
A number of mathematical problems are discussed in great detail the multi-grid method to solve a three-dimensional field distribution, such as deducing the formula of restriction and prolongation, determining the position and domain of conical, cylindric, spherical, and the method of logic ruler encoding. It lays a solid foundation to design and optimize the electron optical system for image tubes.
