射线

• Dense gas serves to reduce the ionization, because it absorbs the ionizing soft x rays .
  因为浓密气体吸收掉了使其电离的软x射线，因此能减少电离。
• Crudely, we might compare the production of x-rays with the stopping of a bullet by a tree .
  我们可以把X射线的产生粗略地与子弹被树挡住这种情形作比较。
• Surgery and x-irradiation nevertheless remain the bulwarks of cancer treatment throughout the world .
  外科手术和X射线疗法依然是全世界治疗癌症的主要方法。
• scorpius x-1 is the brightest x-ray source in the sky in the 1-10 wavelength region.
  天蝎座X-1是在1-10埃波长区全天空最亮的X射线源。
• The instantaneous gamma rays are produced almost entirely before the weapon has completely blown apart .
  瞬时射线差不多是在武器完全飞散之前就全部产生了。
• it is well known that experimental β-ray absorption curves are roughly exponential.
  众所周知，实验上测得的射线吸收曲线大致是指数型的。
• and have been suggested as the best sources of beta rays for these measurements.
  曾有人提出，和是进行这些测量的最好的射线源。
• Heavy metals, such as iron and lead, make good gamma-ray shields because of their high density .
  重金属像铁、铅等由于密度很大，都是防护射线的最好的防护材料。
