Question

particle n.颗粒；微粒；极小量；质点；粒子；[语]小品词 (1) 我们可以很清楚地看到阳光下的灰尘颗粒。(2) 原子是最小的不可分的物质微粒。(3) 他说的没有一点真话。(4) 这质点在流动区域内运动。(5) 这个粒子在所加力的作用下将作加速运动。(6) 在 She tore up the letter 句中，up 便是小品词。 Particles are tiny. If you mean a subatomic particle, that's a body that you can't see because it is so incredibly small, though it does have a miniscule mass and internal structure. These particles are even smaller than atoms. You can also say a crumb or speck of something is a particle. Dust particles are piling up all the time, and vacuuming cleans up lots of particles. Those particles are little bits of things. In both cases, particles are very tiny.
