For five years, those "eyeballs" watched for telltale flashes of light signaling a rare neutrino interaction within the detector volume, and the scientific results made headlines.
根据加西亚博士的说法,这意味着微中子可以像穿过人体的X光一样,用于将密度较大的岩石和较轻的岩石区分开来。
That means they can, according to Dr Gonzalez-Garcia, be used like X-rays passing through a human body, to pick out denser rocks from lighter ones.
这架望远镜被命名为“冰立方”,其工作原理是:当一个微中子撞击冰中的水分子原子时,望远镜就会探测这些罕见的场合中产生的闪光。
Called IceCube, it will work by detecting the flashes of light generated on those rare occasions when a neutrino hits one of the atoms in a molecule of water in the ice.
在反应堆物理设计和分析时,经常要进行微扰计算,以快速分析堆芯中子截面扰动下反应性的变化量。
