词语用法

词义讲解

词源解说

n.(名词)

ray的基本意思是“光束,光线”,一般指发光体如太阳或月亮等发出来的光线,也可作“射线”解,指热、电或其他形式的能的射线,用作这两种意思时,常以复数形式出现。

ray还可作“一线”解,常与a与of连用,意思是“一线…”,表示微量、丝毫。

ray用于比喻可指“智慧之光”。

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。

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