neutrinos
中微子;微中子
neutrinos is the plural of neutrino.
an elementary particle with zero charge and zero mass
- 1.
An elementary particle that is classified as a lepton, and has an extremely small but nonzero mass and no electric charge. It interacts with the surroundings only via the weak force or gravitation, making it very difficult to detect.
一种被归类为轻子的基本粒子,具有极小但非零的质量且不带电荷。它仅通过弱力或引力与周围环境相互作用,因此极难探测。

a/an + [singular noun]
neutrino 是可数名词,单数形式前需加限定词;首音为辅音,用 a 而非 an。

中微子不带电荷。
[plural noun] + [verb]
复数形式 neutrinos 常不加冠词,用于泛指这类粒子;谓语动词用复数。

中微子产生于核反应中。
[noun] + [noun] (attributive)
neutrino 可直接修饰另一个名词,构成复合名词,此时保留单数形式。
