diffraction [dɪ'frækʃən]
n. 衍射
[化] 衍射
[医] 衍射, 绕射
- Diffraction, too, occurs in light waves.
衍射也是由光波产生。 - We offer ruled and holographic diffraction gratings.
我们提供常规和全息衍射光栅。 - The uncertainty principle can account for diffraction.
测不准原理可以说明衍射。
diffraction
[ noun ]
when light passes sharp edges or goes through narrow slits the rays are deflected and produce fringes of light and dark bands
<noun.phenomenon>

<noun.phenomenon>
Diffraction \Dif*frac"tion\, n. [Cf. F. diffraction.] (Opt.)
The deflection and decomposition of light in passing by the
edges of opaque bodies or through narrow slits, causing the
appearance of parallel bands or fringes of prismatic colors,
as by the action of a grating of fine lines or bars.
Remarked by Grimaldi (1665), and referred by him to a
property of light which he called diffraction.
--Whewell.

- "This country had the lead in neutron diffraction in the 1960s and '70s," says Mr. Anderson, "but we let it dribble down the drain," and Europe now has the best facilities for such studies.
