Now the last thing is that because the neutron has no net charge, we can change neutron number.
现在，最后一件事是，因为中子没有净电子，我们可以改变中子数。
This means you can vary the neutron number without changing chemical identity, because chemical identity is fixed by the proton.
这表示你可以改变中子数，而不会改变它的化学特性，因为化学特性是由质子决定的。
So carbon 12. We know that it has the proton number, by definition, is 6. And the neutron number, 6 from 12 is 6. So it has 6 protons and 6 neutrons.
所以碳12，我们知道它有质子数，根据定义，那就是6，而电子数，12减6等于6，所以它有6个中子。
Adopting the physics mode given in this thesis, the accuracy of computed results is within experimental errors if the number of computed neutron is large enough.
按照本文所提出的物理模型，只要计算的中子数足够多，其计算结果可完全在实验误差范围之内。
The black hole could help scientists better understand how massive stars explode, which ones leave behind black holes or neutron stars, and the number of black holes in our galaxy and others.
这个黑洞可以更好地帮助科学家理解超新星爆炸，爆炸后会在本星系或其他星系形成黑洞或中子星。
The black hole could help scientists better understand how massive stars explode, which ones leave behind black holes or neutron stars, and the number of black holes in our galaxy and others.
该黑洞能帮助科学家解惑：大型恒星爆炸以后，它的产物到底是黑洞还是中子星；以及我们或其他银河系里到底有多少黑洞。
