When a charged particle zips through the chamber, the vapour condenses into a trail of droplets showing the particle's path and, if the box is placed in a magnetic field, its electrical charge.

当一个带电粒子快速穿越云室时，水汽会凝结形成一串小液滴，这样便标识出了该粒子的路径；若将容器置于一个磁场中，还能知道粒子所带电荷的性质。

The chamber further contains either: a plurality of particles susceptive to movement in a magnetic field; or one particle susceptible to movement in a magnetic field.

所述腔 还包括可在磁场中运动的多个微粒或可在磁场中运动的一个微粒。

A second chamber is disposed between the diaphragm and the magnetic circuit.

第二腔室设置在振动膜和磁路之间。

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.
