💡 深入解读
Disperse 是一个容易与常见单词 disburse 相混淆的单词。该词由前缀 dis- （加强）+ 词根 spers （散开）+ e 构成，源自拉丁语dispergere（分散）。14世纪末进入英语后，先是用作及物动词表示“使烟、雾、云等分散、散开、消散”，以及“驱散、疏散”示威者、暴民、人群、船只、飞机等，侧重强调聚集体或者组合体朝着不同方向完全分解，也就是彻底驱散，相对于scatter而言构成单元的分离扩散更为广阔，
比如：
The cattle were swinging their tails to disperse the flies.那些牛甩动着尾巴驱赶苍蝇。
Police dispersed the protesters with tear gas. They were egged on by Mr Trump.警察用催泪弹驱散了抗议者。他们受到了特朗普的煽动。
Gangs of youths went on the rampage in the city yesterday. At last they dispersed and melted into the darkness.到了16世纪20年代后，也开始用作不及物动词表示示威者、暴民、人群、船只、飞机等“散去”以及烟、雾、云等“消散、消失”，比如：成群结伙的年轻人昨天在城里横冲直撞。最后他们散开了，消失在夜幕之中。
用在物理学中， disperse 还可以表示“使光色散”，比如：三棱镜可使光色散。
A prism disperses light.
