Each cable is equipped with another four sensors at the surface, which together make up one IceCube array.

每束电缆还装备了另外四个置于冰面的传感器，这些传感器组合在一起形成了一个冰立方阵列。

IceCube takes advantage of neutrinos' slipperiness, using Earth as a filter of more interactive particles.

冰立方利用了中微子的滑溜，将地球作为一个对更容易发生相互作用的粒子的过滤器。

Interestingly, an April 18 paper in the journal Nature reported that upper limits for neutrinos measured from IceCube are low enough that gamma-ray bursts are unlikely to be the sole source of ultra-high energy cosmic rays.

The world's most powerful neutrino telescope, IceCube, uses Antarctic ice as the detector volume, with electronic equipment sunk throughout a cubic kilometer of ice -- enough water to fill a million swimming pools -- to detect signals from neutrinos interacting with the ice.
