neutrons

• Neutrons in the slow and moderate speed ranges can produce ionization indirectly in other ways .
  慢中子和中能中子可以通过其它方式产生间接电离作用。
• Indirect ionization by neutrons can also result from fission of plutonium or uranium isotopes .
  通过使钚或铀同位素裂变，中于也能产生间接的电离作用。
• Standard field procedures are employed in taking samples for analysis by delayed neutron determinations .
  采用标准的实际操作规程为缓发中子测定分析取样。
• There appeared to be no gross distortions of the neutron spectrum expect at energies below 2 mev .
  除了2兆电子伏以下的能量外，中子谱似乎不存在显著的畸变。
• The interval is two mass units because these isotopes of the elements differ by two neutrons .
  因为这些元素的同位素相差两个中子，所以其间隔为两个质量单位。
• The modes of interaction of neutrons with matter are quite different from those experienced by gamma-ray photons .
  中子与物质的相互作用方式和射线光子完全不同。
• Two protons brought together will also fly apart-if neutrons are not present to hold them together .
  两个靠拢的质子也会飞开--如果不是有中子把它们保持在一起的话。
• In certain fusion processes, among nuclei of the hydrogen isotopes, neutrons of high energy are liberated .
  在氢同位素原子核中的某些熔合过程中，会释放出高能中子。
• It is for this reason that hydrogen, e. g. as water, is an important constituent of neutron shields .
  由于这一缘故，氢（例如水）便成为中子屏蔽体的一个重要组成部分。
• This device is absolute in the sense that it does not require calibration in a known field of neutrons .
  从不必要在已知的中子场中进行刻度的这意义上讲，这种装置是绝对的。
