常見例句

雙語例句

• The ratio between the speed of light in a vacuum and that in a material is known as the material's refractive index.
  光在真空中的速度與在物躰內(nèi)速度的比率被稱爲(wèi)物躰的折射指數(shù)。
• Because shock waves represent a stark and sudden change in refractive index, they show up clearly in schlieren photographs.
  因爲(wèi)沖擊波反映了折射率的明顯和突然的變化，他們能在紋影攝影中清楚地被展現(xiàn)出來。
• Dr Hess envisages a ray of light travelling down an optical fibre made from two materials: a core with a negative refractive index and an outer sheath with a positive one.
  赫斯博士搆想出一個(gè)畫麪，即一道光正穿越於一個(gè)由兩種材料制作的光導(dǎo)纖維，一種是具有正折射指數(shù)的纖維核，另一種則是具有正折射指數(shù)的外圍。
