142 dilate

英音[dai'leit];美音[dai'let]

(esp. of parts of the body)to become wider or further open by stretching

v.扩大,膨胀,张大;详述

同义amplify, distend反义shrink名词dilatation

解析:dilate来源于拉丁文di-(分开)+-late(放),其字面意思为分开放,那自然会“扩大”占地面积。

●amplify, distend与dilate的一般含义是扩张或增大。

amplify所指的扩大规模不充分、不清晰、缺少细节,用做比喻时,意为夸大、夸张。例如:His voice is amplified by microphone.(他的声音被扩音器放大了。)

distend指由内部压力而引起膨胀或扩张。例如:The big balloon was distended for being full of hydrogen.(大气球因充满了氢气而膨胀。)

dilate意为加宽或增大,尤指圆形物体的加宽或延伸。例如:I feel I need to dilate my pupils to remain attentive.(我觉得需要扩大瞳孔才能集中精神。)
