Neutrinos from a subsidiary decay process are the ones to be detected. 将探测到来自次要衰变过程的微中子。
In particular, the rest-mass of neutrinos would have important influence on those cosmic problems related with mass density, such as the problems of whether the universe being open or not, the gravitational clustering in the universe, and so on. 特别是,对于那些与质量密度有关的宇宙学问题,例如宇宙的封闭或开放、宇宙中的引力成团过程等等,中微子的静质量有明显的作用。
Stars are as thick as the sand grains on a beach. Every star is a copious source of neutrinos. 恒星像海滩上的沙子那样密集。每颗恒星都是丰富的中微子源。
Experimenters who study collisions of neutrinos with nuclei experienced frustrations of a different sort-an excess of riches. 原子核碰撞中微子研究的实验工作者经历了另一种类型的困难&资料过多。
The team shook the world two months ago with its claim that neutrinos could beat the speed of light. 两月前,该小组宣布中子运行速度可以超过光速,这震惊了全世界。
What is the quality of neutrinos? 查看完整版本:中微子的质量是多少?
Neutrinos and the hypothetical gravitons, also massless particles, move at the same speed as light. 中微子和假想的引力子也是无质量粒子,它们也以与光相同的速度运动。
At least, in weak interaction, neutrinos may be superluminal particles. 至少在弱相互作用中,中微子可能是超光速粒子。
FAITH LAPIDUS: The MINOS experiment may also measures neutrinos traveling faster than the speed of light. 米诺斯实验将通过实验测量微中子的速度是否比光速快。
There is a good chance that this outward diffusion of neutrinos and antineutrinos plays a crucial role in the supernova explosion. 中微子和反中微子的这种向外的散射很可能在超新星爆发中起着关键的作用。
And they said their observations appear to show that the neutrinos traveled faster than light. 他们认为这些观察结果证明了:微中子的运动速度比光速快。
Standard theory predicts that two neutrinos are produced for every fusion of four protons into a helium nucleus. 标准理论预言,在由四个质子变成一个氦核的每一次聚变过程中要产生两个中微子。
They carried out an experiment that fired a beam of neutrinos from CERN to Italy's INFN Gran Sasso Laboratory. 他们做了一个实验从CERN实验室发送了一束微中子到意大利的意大利格朗萨索实验室。
Supraluminal neutrinos, if they really exist, are something completely new. 超光速中微子如果真的存在,这将是物理界新的革命。
Strictly speaking, the Daya Bay experiment looked at antineutrinos rather than neutrinos. 严格来说,大亚湾这个实验观察的是反中微子而不是中微子。
Every star is a copious source of neutrinos. 每颗恒星都是丰富的中微子源。
They can "oscillate" or change identities, which means that the mu neutrinos produced at the LHC can turn into tau neutrinos which the OPERA detector is designed to measure. 它们能“振动”或改变形态,这意味着LHC产生的μ子中微子可以转变为OPERA探测器设计用来测量的τ子中微子。
The possibilities for neutrinos are less constrained by previous measurements, he says. 而之前的测量结果对于中微子的约束要小一些。
The researchers claim to have used a more accurate method for the second trial, by sending shorter bunches of the tiny neutrinos with larger gaps in between. 研究人员在第二次实验中采用了更精确的方法&发送较短的中微子束,并且将发送时间用较长的时间间隔开来。
Ordinarily, neutrinos and antineutrinos readily escape from stellar interiors without making collisions. Any emitted photons are trapped into an orbit by the intense gravitational field; they will never leave it. 通常,中微子和反中微子容易无碰撞地从星体内部逃逸出去。恒星发出的任何光子都被强大的重力场所吸引,使其陷入其周围轨道,永远也不会逃逸。
