记录元素浓度的测井方法，利用中子轰击原子核，使其激活后释放出伽马射线，根据伽马射线的特征能量级可获得元素浓度。
A log of elemental concentrations derived from the characteristic energy levels of gamma rays emitted by a nucleus that has been activated by neutron bombardment.
然后，用第二个磁场短时轰击这些原子核，使其脱离第一个磁场阵列。
These nuclei are then zapped briefly with a second magnetic field that knocks them out of alignment with the first one.
当一个中子轰击一个原子核的时候，这个核可能会俘获这个中子，从而变的极不稳定。
When a neutron hits an atomic nucleus, the nucleus can absorb the neutron and become unstable.
我们暂且称之为117号元素，因为在它的原子核内有117个质子。它是由位于杜布纳的联合核研究所通过轰击钙离子而得到的。
Temporarily known as ununseptium, because it has 117 protons in its nucleus, it was made at the Joint Institute for Nuclear Research in Dubna by smashing calcium ions into berkelium atoms.
