neutrons

• These elements alone, however, are not quite as satisfactory for neutron shielding .
  然而，单用这些物质来防护中子不见得十分令人满意。
• A neutron has no appreciable electromagnetic interaction with nuclei or with electrons .
  中子与原子核或与电子并没有可察觉的电磁相互作用。
• The presence of boron or a boron compound in neutron shields has certain advantages .
  在中子防护体中加入硼或一种硼的化合物是有一定优点的。
• A-fe2o3 (haematite) was one of the first compounds to be studied by neutron diffraction .
  A-Fe2O3（赤铁矿）是中子衍射最先研究的化合物之一。
• The neutron counter was designed and made at awre to achieve these parameters .
  达到上述指标的中子控测器是在原子武器科学研究中心设计并制造的。
• The minus sign indicates that the work done by the force decreased the kinetic energy of the neutron .
  负号表明这个力所作的功降低了中子的动能。
• The shortage of neutrons in u-235 seems to give its atoms a strange sort of instability .
  在U-235中缺少中子似乎给予U-235原子一种奇异的不稳定性。
• First was the discovery in 1932 of the neutron by the british experimenter j. chadweek .
  其中第一件事是英国实验工作者查德威克在1932年发现了中子。
• Since neutrons have no charge, they produce no ionization in their passage through gases .
  因为中子没有电荷，所以它们在经过气体时不产生电离作用。
