electron
意味: A stable subatomic particle with a negative electric charge that orbits the nucleus of an atom and is responsible for chemical bonding and electrical conductivity.
Electrons are fundamental to chemistry and electronics. Chemical bonds form when atoms share or transfer electrons. The flow of electrons through a conductor constitutes an electric current. In quantum mechanics, electrons exhibit wave-particle duality, behaving as both particles and waves. The adjective 'electronic' derives from this word and has become ubiquitous in modern life.
例文
- Electrons orbiting the nucleus determine the chemical properties of an element. 围绕原子核运行的电子决定了元素的化学性质。Los electrones que orbitan alrededor del núcleo determinan las propiedades químicas de un elemento.原子核の周りを周回する電子が元素の化学的性質を決定する。원자핵 주위를 도는 전자가 원소의 화학적 성질을 결정한다.
- An electric current is essentially a flow of electrons through a conductive material. 电流本质上是电子通过导电材料的流动。Una corriente eléctrica es, en esencia, un flujo de electrones a través de un material conductor.電流とは本質的に導電性材料を通る電子の流れである。전류란 본질적으로 전도성 물질을 통한 전자의 흐름이다.
- The electron microscope uses beams of electrons to produce images at far higher magnification than optical microscopes. 电子显微镜使用电子束产生比光学显微镜高得多的放大倍率的图像。El microscopio electrónico utiliza haces de electrones para producir imágenes con una magnificación muy superior a la de los microscopios ópticos.電子顕微鏡は電子ビームを使い、光学顕微鏡よりはるかに高い倍率の画像を生成する。전자현미경은 전자 빔을 사용하여 광학현미경보다 훨씬 높은 배율의 이미지를 생성한다.
