particle n. 1.颗粒,微粒;微量,极少量。 2.【物、数】粒子,质点。 3.【语法】虚词,不变词〔冠词、副词、介词、连接词、感叹词等〕;小品词 〔yes, no 等〕,词缀。 4.〔古语〕(文件中的)条,项。 5.【天主教】一小片圣饼。 He has not a particle of sense. 他一点脑子也没有。 fundamental [elementary] particles 【物理学】基本质点,基本粒子。
Decaying with relatively short lifetime . used of subatomic particles 衰变的具有相对较短的寿命而衰变,常用于亚原子粒子
Small as they are , atom is made up of still smaller unit know as subatomic particle 原子虽小,但它们是由更小的称为亚原子粒的单位组成的。
Also , in quantum mechanics , the use of the term particle refers to an elementary or subatomic particle 同样在量子力学里,使用术语粒子指的是一基本或亚原子粒子。
Eventually , we would create another sub - level of subatomic particles that would become dense matter 最后,我们会创造另一种亚原子微粒的低层面级别,亚原子微粒会变成为稠密物质。
Luminescence is caused by chemical , biochemical , or crystallographic changes , the motions of subatomic particles , or radiation - induced excitation of an atomic system 发冷光是由化学,生化或结晶变化,亚原子颗粒的运动,或原子系统的辐射产生的。
Neutrino is an electrically neutral subatomic particle , which has very little interaction with any other matters . hence , the star will be transparent to them 中微子是亚原子粒子,它们差不多不会和任何物质产生反应,所以恒星对它们来说是透明的。
When scientists first turned their attention to subatomic particles , including cosmic rays , they used a device called a cloud chamber to study them 科学家们首次将注意力转向亚原子微粒(包括宇宙射线) ,并使用一种名为“云室”的装置对其进行研究。
When scientists first turned their attention to subatomic particles , including cosmic rays , they used a device called a cloud chamber to study them 当科学家们首次把研究的焦点放到亚原子粒子(包括宇宙射线) [ 3 ]上时,他们使用一种称作“云室”的装置进行观察。
As matter cooled , highly energetic subatomic particles slowed enough to interact with each other , filling the universe with the simplest elements of hydrogen and helium 当问题冷却了,高度精力充沛的亚原子的微粒足够减慢互动互相,填装宇宙用氢和氦气的最简单的元素。
Physicists cannot see subatomic particles directly , for instance , so they verify their existence by watching for telltale tracks that the particles leave in cloud chambers 例如物理学家无法直接观察次原子粒子,因此他们观察那些粒子在云雾室中的轨迹,轨迹证实它们的存在,并透露了它们的性质。
