这种小型设备的不同区域表面覆盖有相同的DNA分子簇，我们称之为探针。
These small devices are coated with clusters of identical DNA molecules, called probes, within separate areas.
这些粒子主要是质子、电子和氦原子核，并且当他们与地球高层大气中的原子核碰撞，就能产生次级粒子簇射。
The particles are generally protons , electrons and helium nuclei and when they collide with nuclei in the Earth's upper atmosphere they can produce shower s of daughter particles.
因为中微子几乎不与其它物质相互作用，它们穿透土地流动，之中很小的一部分撞击在探测器上，成为可以观测到的粒子簇。
As the particles hardly interact at all with other matter, they stream right through the ground, with only a very few striking the material in the detector and making a noticeable shower of particles.
