But some astronomers always suspected that the remaining antiprotons must become trapped by the Earth's magnetic field, forming an antiproton radiation belt.

但是一些天文学家一直怀疑，那些剩下的反质子一定被地球磁场捕获，形成一条反质子辐射带。

The distribution of the induced current density and the profile of the trapped magnetic field in a superconducting disk magnetized by magnetic pulses are calculated from first principles.

本文从第一性原理出发，计算了充磁线圈产生的磁场，脉冲充磁的超导圆盘中的感应电流密度和俘获场分布。

This conical beam is then reflected into a cluster of 1m or so rubidium atoms, which are held trapped in a magnetic field within a vacuum chamber.

But gamma-ray telescopes are also confused by charged particles trapped in the earth's magnetic field.
