The effect of confining magnetic field on the radial profile of axial electric field is studied.
ITER的目标是通过使约束在强磁场内部的高温氢原子核发生聚变而产生能量——这个过程跟太阳的供能方式很相似。
ITER aims to produce energy by fusing together the nuclei of hydrogen atoms, confined in a magnetic field at high temperatures-a process akin to that which powers the sun.
如此极其精确的时钟是建立在单一铝离子的快速振动，铝离子就是包含在真空中受电磁场约束的失去一个电子的原子。
Such ultra-precise clocks are based on the quick vibrations of a single aluminum ion, an atom that has lost one electron, held in a vacuum and confined by electromagnetic fields.
