英语翻译
Neutrinos are elementary particles that often travel close to the speed of light,are electrically neutral,and are able to pass through ordinary matter almost undisturbed and are thus extremely difficult to detect.Neutrinos have a minuscule,but nonzero mass.They are denoted by the Greek letter ν nu.
Neutrinos are created as a result of certain types of radioactive decay or nuclear reactions such as those that take place in the Sun,in nuclear reactors,or when cosmic rays hit atoms.There are three types,or "flavors",of neutrinos:electron neutrinos,muon neutrinos and tauon neutrinos (or tau neutrino); each type also has a corresponding antiparticle,called antineutrinos.Electron neutrinos (or antineutrinos) are generated whenever neutrons change into protons (or protons into neutrons),the two forms of beta decay.Interactions involving neutrinos are mediated by the weak interaction.
Most neutrinos passing through the Earth emanate from the Sun,and more than 50 trillion solar electron neutrinos pass through the human body every second

中微子是一种补充粒子以接近光速的速度移动,电学上呈中性,并能够几乎毫无阻碍的穿透物质,并因此极难被侦测到.中微子有着极小的但不为零质量,并以希腊字母v标注.
中微子是由于特定种类的放射活动衰变或原子反应比如太阳中发生的反应而产生的.在原子反应堆中,或宇宙射线撞击原子时,有三种类型或说是"种类"的中微子:电子型中微子,介子型(μ)中微子和陶(τ)型中微子.每种类型都有相应的反粒子,称为反中微子.电子型中微子(或反中微子)在中子转化为原子时(或原子转化为中子时)被生成,即两种贝塔(β)衰变的模式.包含中微子的反应由弱反应作质粒中介.
大部分照射于地球的中微子由太阳产生,而且,每秒钟有超过50万亿的太阳电子型中微子穿过人体.
