在一个原子的核内，中子和质子聚合在一起。
Neutrons and protons are bound together in the nucleus of an atom.
原子本身是个整体，含电子、质子、中子以及其他组成部分。
An atom itself is a complete whole, with its electrons, protons and neutrons and other elements.
如果条件合适，它们将结合、聚变，形成鐽中子。
If the conditions are right, they will combine, fuse and form darmstadtium plus neutron.
给定元素的所有同位素都含有相同的质子数，但它们的中子数不同，因此它们的原子质量也不同。
All the isotopes of a given element have the same number of protons, but differ in their number of neutrons, and hence in their atomic mass.
重水之所以重是因为水中氢的重量是普通氢的两倍（它的原子核中有一个质子和一个中子，而不仅仅是一个质子）。
Heavy water is heavy because the hydrogen in it weighs twice as much as ordinary hydrogen (it has a proton and a neutron in its nucleus, instead of just a proton).
这项工作为詹姆斯·查德威克爵士发现中子铺平了道路，尤其是为伊莲娜和弗雷德里克·约里奥特·居里在1934年发现人工放射性奠定了基础。
This work prepared the way for the discovery of the neutron by Sir James Chadwick and, above all, for the discovery in 1934 by Irène and Frédéric Joliot-Curie of artificial radioactivity.
中子走进一个进酒吧，坐在吧台。
控制棒是由能够吸收中子的硼元素制成。
中子的速度越快，它所击破的原子就越少。
氚原子多了两个中子。
你是中子，他说，是是，我是中子。
那时中子平衡等式，如果你想，用材料来表示。
That's the neutron balance equation if you want, represented in terms of the materials.
我们也产生中子。
我们产生中子。
但是它并不影响到中子。
所以，我们不只在寻找能量E的中子,从这个光谱中。
So we're looking only for the neutrons at energy E from this spectrum.
反中子逃离大气，然后在高得多的区域衰变为反质子。
The antineutrons escape the atmosphere and then decay into antiprotons at much higher altitudes.
如果条件是正确的，它们将会结合，融合并形成鐽中子。
And, if the conditions are right, they will combine, fuse and form darmstadtium plus neutron.
所以，我们可以间接得到中子数，因为我们知道质子数了。
So we get at the number of neutrons indirectly because we know the proton number here.
因为我们没有电荷补偿，我们就可以随意地加上火减少中子。
And since we don't have to charge compensate, we can add or subtract neutrons at liberty.
所以，这是基本的等式,那是我们能写下来描述中子如何,积累的过程。
So this is the fundamental equation that we can write that describes how neutrons in fact do accumulate.
中子过多会让裂变反应失控，中子过少则会让裂变反应停止。
Too many neutrons can cause a fission reaction to get out of control. Too few neutrons and a fission reaction stops.
如果引力压过中子简并压，中子星将被压成一个奇点，变为黑洞。
If the gravitational pressure overwhelmed the neutron degeneracy pressure, the neutron star would be crushed into a singularity, producing a black hole.
但他们也并不需要从一颗真正的中子星表面挖来一块中子星简并物质。
But they didn't have to scoop a chunk of neutron degenerate matter from the surface of a real neutron star either.
周围有125个辅助中子，有75个副中子和，111个辅助副中子。
It has 125 assistants to the neutron, it has 75 vice neutrons and 111 assistants to the vice neutrons.
而开始重组，其中，副中子，辅助中子，辅助副中子，开始交换位置。
Then it undergoes a reorganization in which the vice neutrons, assistants to the neutron, the assistants to the vice neutrons exchange places.
综上，中微子就是极小的中子，是它被发现以来除中子外唯一的中性粒子。
So they were baby neutrons, which were the only other neutral particles at the time that were known.
综上，中微子就是极小的中子，是它被发现以来除中子外唯一的中性粒子。
So they were baby neutrons, which were the only other neutral particles at the time that were known.
