neutrino

音標發(fā)音

This is heady wine for experimenters using these neutrino detectors.
對于使用中微子探測器的實驗工作者,這是令人興奮的美酒.
This property, often called " helicity,'serves to differentiate the neutrino from its antiparticle.
這種性質通常稱為 “ 螺旋性”, 可以用來區(qū)分中微子和它的反粒子.
The physical characteristics of the neutrino are remarkable.
中微子的物理特征非同尋常.
The physical characteristics of the neutrino are remarkable.
中微子的物理特征非同尋常.
The reality of the neutrino had to be accepted on the basis of rather indirect evidence.
不得不基于相當間接的證據(jù)來承認中微子的存在.

a very small piece of matter that has no electrical chargeand exists for a very short time, produced during some types of nuclear reactions

a stable leptonic neutral elementary particle with very small or possibly zero rest mass and spin that travels at the speed of light. Three types exist, associated with the electron, the muon, and the tau particle

中微子
The density ranges where direct lerca processes of both electorns and muons are allowed can be changed. On the other hand,∑ hyperons lower the neutrino emissivity obviously,so it maybe not suitable for the fast cooling of neutron stars.
∑超子在冷卻方面的效應更加明顯,一方面,它們改變電子和μ子的直接Urca過程的發(fā)生范圍,另一方面也使得中微子發(fā)射率大幅降低,因此∑超子可能并不利于中子星冷卻。
