For the typical high energy electron spectrum in outer radiation belt, the charging time for dielectrics is of the order of an hour.

对于典型的外辐射带高能电子能谱情况，介质的充电时间为小时量级。

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。

Radiation detectors come as hand-held devices, wrist watches and pager-size gadgets that hang from the belt.

辐射探测器有几种型号，有的是手持设备，有的腕式手表一样，有的像寻呼机一样挂在皮带上。

Sceptic: If the Apollo astronauts had really travelled to the moon, they would have been cooked by a giant belt of lethal space radiation.

质疑者：如果阿波罗号的宇航员真的到达了月球，他们会被一条巨大而致命的空间放射带给烤熟。

They are irregular forms of the oxide film, belt-, radiation-network-, crack-and hair-like oxide film etc, which are ex-tending and forming in the direction of deformation.

它们是无规则形状的氧化膜，沿变形方向延伸呈带状、放射状、网络状、 裂纹状、毛发状等。
