n.名词
C微粒,颗粒,粒子a very small piece C极少量smallest possible amount C小品词any of a number of usually short words that are not as important in a sentence as the subject, verb, etc.
Noun:
nontechnical usage a tiny piece of anythinga body having finite mass and internal structure but negligible dimensionsa function word that can be used in English to form phrasal verbsmolecule，atom，particle，speck，grain这些名词均有“粒、微粒”之意。 molecule指物质中保持原物质的一切化学性质，能独立存在的最小微粒，即分子。 atom指元素的最小粒子，其体积比molecule小。 particle指任何物质的微粒，引申指任何小的部分。 speck一般指“微点”或“微粒”，可引申指“斑点、污点”。 grain通常指能为肉眼清楚看到的颗粒，比上述几个词所表“粒”的体积大。 来自part,部分，-icle,小词后缀。即小部分，引申词义个体，颗粒，微粒。
用作名词 n.
