【摘要】 <正> 多体环状永磁多极系统场形的解析分析工作,我们是从1978年结合“八七”工程输运磁铁设计,陆续开展起来的。本文论述的主要是多体平头环状(即磁体内边缘是平直端面,外边缘是弧形)永磁四极透镜的二维场形分布及其与普通电磁透镜的性能比较问题。更多还原

【Abstract】 According to the principle of "Uniform magnetization" the 2-dimensional space exprer ssion for the constant direction magnetized multi-piece ring structure with plane head is given by the method of harmonic analysis. The imaginary project of 16-piece plane head quadrupole is computed, and comparison has been made with selected ordinary electromagnetic lens system.更多还原
