Forward Scattering

Definition / 定义

forward scattering前向散射。指波(常见为光、声或粒子束)与介质/粒子相互作用后,散射能量主要集中在与入射方向接近(小角度)的方向上。常见于光学、遥感、大气物理、粒子物理与生物组织成像等语境。(也可与“backward scattering/后向散射”相对。)

Pronunciation / 发音

/frwrd sktr/

Examples / 例句

Forward scattering increases when the particles are large compared with the wavelength.
当粒子的尺寸相对于波长更大时,前向散射会增强。

In foggy conditions, strong forward scattering of headlights can reduce contrast and make it harder to see the road clearly.
在有雾的情况下,车灯的强前向散射会降低对比度,使人更难清晰看见道路。

Etymology / 词源

forward 源自古英语 foreweard(意为“朝前的、在前方的”),scatter 源自中古英语 scateren(意为“使分散、散开”)。组合成 forward scattering,字面即“朝前方向的散射”,用于描述散射角分布在前方占优势的物理现象。
