摘要

通过核磁共振测量的磁通密度不同于平均磁通密度，因为磁通密度的空间变化会引起线形不对称，从而使测量频率发生测量依赖量的偏移。已经设计出一种方法来纠正这种影响，并进行了理论检验。

Achieving high precision in NMR flux density and /spl gamma/'/sub p/ measurements-accounting for the asymmetric line

Flux density measurements via nuclear magnetic resonance differ from the average flux density because spatial variations of the flux density cause line-shape asymmetries which shift the measured frequency by a measurement dependent amount. A method has been devised for correcting for this effect and tested against theory.<>
