摘　　要：在曲轴宽电子束聚焦理论的基础上，本文研究了具有设定图像旋转角的曲轴电磁聚焦成像理论，进一步发展了作者先前的电磁聚焦成像理论，导出了在设定图像转角下系统曲轴场系数应满足的条件，作为例子，讨论了几种能够实现设定图像旋转角的曲轴电磁聚焦成像系统中的曲轴场系数的分布。On the basis of electrostatic and magnetic imaging theory having curvilinear axes, are investigated the theory with any specified image rotation and further developed author's previous theory. The conditions that should be satisfied in curvilinear axial field coefficient with any specified image rotation were derived. As examples, several curvilinear axial field coefficient distributions that can realize any specified image rotation were discussed.
