射线

• With the ease, radiation detectors can be used semi-quantitatively in the field .
  使用射线探测器可以很方便地进行野外半定量测定。
• They use x-ray diffraction to determine the structures of proteins and nucleic acids .
  他们应用X-射线衍射确定蛋白质和核酸的结构。
• Radiation is only detected from a relatively narrow strip adjacent to the track of the vehicle .
  射线仅来自汽车路两侧较窄的条带。
• A high beam energy is also used to stimulate x-ray emission of higher-energy peaks .
  高能量电子束也能用来激发高能量X射线峰的发射。
• With radio and x-ray telescopes, we find many signs of violent activity .
  依靠射电望远镜和x射线望远镜，我们发现了许多迅猛活动的迹象。
• Contribute a little to either ultra-violet astronomy or x-ray astronomy .
  所以气球携带的仪器对紫外线天文学或Ｘ射线天文学的贡献是不大的。
• To exclude the γ-ray counts, all pulses below a fixed level are rejected .
  为了剔除射线的计算，也就剔除了低于某一固定水平的所有脉冲。
• As a result, there is less attenuation of the gamma rays from the fission products .
  这样一来，从裂变产物中发射出来的射线的减弱就要少一些。
• The renowned american satellite uhuru exemplifies the capabilities of x-ray astronomy .
  著名的美国“乌呼鲁”卫星充分显示了X射线天文学的威力。
• Consequently, gamma rays will reach a particular target on the ground from many directions .
  这样，射线必将从四面八方射达某一指定的地面目标。
