neutron造句

2. One of these techniques is neutron activation analysis.
3. Another such state is a neutron star.
4. First, then, what about neutron decay?
5. Even more persuasive are small angle neutron scattering studies.
6. They were therefore called neutron stars.
7. A neutron decays into a proton, electron and neutrino.
8. The neutron production rate appeared to rise after about an hour of electrolysis and then dropped dramatically after eight hours.
9. However, the discovery of the neutron and of nuclear forces disappointed those hopes.
10. The neutron observations may help cast new light on solar flares and solar activity.
11. The proton has positive electrical charge, the neutron has none.
