中子

• 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。
• It can be characterized as a composite of three types of particles: protons, neutrons, and electrons .
  它们可以用质子、中子、电子这三种粒子的组合来表征。
• 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 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。
• Uranium analysis by the emission of delayed neutrons, following fission of u235, has been described by amiel .
  阿密尔论述了应用U235裂变后产生的缓发中子流分析铀的方法。
• 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。
• A rudimentary description of a nucleus consists in specifying the number of protons and neutrons it contains .
  对某个原子核的初步描述，在于确定它所含的质子和中子的数目。
