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。

While the superconducting tape can carry very high currents and withstand large magnetic fields and still retain its zero resistance, this is only true with direct current.

虽然超导电缆能够在传导强大电流并经受强烈磁场的同时保持其零电阻，但是这仅限于直流电。

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