波长

• To detect shorter wavelengths, astronomers must put instruments above the earth's atmosphere .
  要探测到更短的波长，天文学家们就必须把仪器送到地球大气层以外去。
• Because these wavelengths are so small, it is convenient to express them in terms of a small unit of length .
  由于这些波长很小，因而用小的长度单位来表示更方便。
• we give the wavelengths of the k lines for some of the elements in table 2. 1, in units of cm.
  表21中列出某些元素的K线波长，以cm为单位。
• Each of the chemical elements that makes up the objects radiates at its own characteristic wavelength .
  构成这些天体的每一种化学元素都会以它们特有的波长发出辐射。
• The dyes are exposed to a minimum amount of radiation after preparation and during addition to the emulsion .
  这些染料制备后，加到乳剂中只对辐射中局部波长的光敏感。
• The evidence seemed inescapable that light consisted of electromagnetic waves of extremely short wavelength .
  光是由波长极短的电磁波组成，这一事实看来已经证据确凿。
• It shows well-defined wavelengths which are characteristic of the structure of the metal forming the anode .
  它显示出那构成阳极的金属的结构所特有的，十分确定的波长。
• The neon lights that adorn our city streets have a spectrum consisting of a few wavelengths near the red end .
  使城市街道生色的氖灯的光谱由一些靠近红色端的波长组成。
