For example, background particles tend to produce more ionization than a nucleus recoiling from a neutralino collision.
例如，背景粒子和一个与中性伴子碰撞而反冲的原子核相比，前者将造成更多的游离。
It will therefore be possible to work out which direction the neutralino that caused it to recoil came from and thus engage in a form of dark-matter astronomy.
由此就可以计算出发生碰撞的中轻微子的来向，甚至产生一门暗物质天文学。
In fact, based on the expected neutralino mass and its low tendency to collide, the total mass in neutralinos almost exactly matches the inferred mass of dark matter in the universe.
事实上，从中性伴子预估的质量及它不易碰撞的倾向可得出：中性伴子的总质量与我们推算宇宙中暗物质的质量几乎完全相同。
