讨论了用矩阵表示电子透镜的方法。结果表明，用矩阵表示透镜更方便、更自然，而且矩阵元素比焦距性质表现出更规则的行为。因此，在计算机程序中使用矩阵更加方便。给出了双管静电透镜的矩阵元素，并讨论了它们的性质。给出了近似单位电压比透镜的矩阵元的简单解析形式。
The use of matrices to represent electron lenses is discussed. It is shown that it is more convenient and natural to represent a lens by a matrix and that the matrix elements show a more regular behavior than do the focal properties. Thus matrices are more convenient to use in computer programs. Matrix elements for the two‐tube electrostatic lens are presented and their properties discussed. A simple analytical form for the matrix elements of lenses with near‐unity voltage ratios is given.
