1.名詞C1
釋義

one of the smallest known types of particle in physics. Neutrinos have no electric charge and an extremely tiny amount of mass. They are produced by nuclear reactions—for example inside the Sun and other stars—and they pass through ordinary matter with almost no interaction, making them very difficult to detect.

例句

Neutrinos from the Sun pass through your body every second without you feeling anything.

pass through [body/surface] without [noticeable effect] — particle behaviour pattern

Scientists built a huge detector in an old mine to study neutrinos coming from space.

detector + built in [location] + to study [source] — scientific setup pattern

同義詞
  • elementary particle

    a broader category; neutrinos are one type of elementary particle, along with electrons and quarks

  • lepton

    a more technical physics term; neutrinos belong to the lepton family of particles, which also includes electrons and muons

文法句型

a neutrino / neutrinos

[number] neutrinos

用法筆記

The plural form 'neutrinos' is far more common than the singular because the particle is typically discussed as a collective type. The word appears most often in scientific and popular science writing rather than in everyday conversation.

A neutrino has almost no mass.
💡Neutrons are much heavier particles found inside atomic nuclei; neutrinos are a different, far lighter particle.
