Such systems face an additional contribution to the inhomogeneity of the radio frequency (RF) field when high magnetic fields are applied.

当施加高磁场时，这种系统会面临对射频(RF)场不均匀性产生额外作用的问题。

Van Allen described how the Earth is surrounded by belts of high-energy particles — mainly protons and electrons — that are held in place by the magnetic fields.

范-艾伦描述了地球是任何被高能粒子带(主要是质子和电子)包围着，地球用磁场拉住它们。今天，这些辐射带被称为范-艾伦带。

With no charge and practically no mass, high-energy neutrinos pass unperturbed through interstellar magnetic fields.

高能中微子没有电荷，事实上，甚至没有质量，所以它们可以毫无阻碍地通过星级间的磁场。

Large stars end in the more spectacular explosions known as supernovae, which generate fast-moving particles in extraordinarily high magnetic fields.

That conundrum was solved by getting the high-frequency signals to penetrate deeper using alternating waves of electric and magnetic fields.
