词义辨析

n. (名词)

ray, beam

• 这两个词的共同意思是“光线”。其区别是：
• 1.beam指由日、月、灯或激光器等发出的有一定宽度的光线，即光束、光柱; ray指由发光体发出的成为线形的光。ray在科技术语中又指射线。用于比喻则可指智慧等的闪光。
• 2.在通俗用法中beam是比ray更强的光线; ray是构成beam的许多光线中的一条。例如:
• There I saw the glorious beams of the rising sun.在那里我看见了初升太阳的光芒。
• The searchlight sent its beam into the night sky.探照灯的灯光射入夜空。

词源解说

• ☆ 直接源自古法语的rai，意为光线；最初源自拉丁语的radius，意为光线。
