自屏蔽式核磁共振仪磁铁的优化设计

The best design of the magnet of self-shielded nuclear magnetic resonator

利用磁导法对自屏蔽式核磁共振仪磁铁设计中的漏磁系数σ进行分析,很好地解决了该系数的计算.这种方法既简单又很适用,用该方法计算出的σ与有限元方法验证得十分吻合.

Analyzed leakage coefficient σ in design of the magnet of self-shielded nuclear magnetic resonator by permeance＇s method and calculated it. This method is simple and available to students. Leakage coefficient σ calculated by this method, which is available, is equivalent to that it is certified by method of finite element.
