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.
这个基本的等式是用来描述中子如何积累的过程。
This basic equation is used to describe how neutrons accumulate.
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.
中子携带的能量可转化为热能。
The neutron would carry energy that could be converted into heat.
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。
上平板用于吸收中子,下板可以反弹它们。
The upper plate absorbs neutrons, and the lower plate reflects them.
它是质子数加上中子数。
我们可以用中子来做。
这里面有质子和中子。
中子星旋转的计时,如果中子星。
氚原子多了两个中子。
你是中子,他说,是是,我是中子。
我们也产生中子。
这个中子星,由于它不是很好理解,正向我们闪耀。
This neutron star for reasons that is not well understood is blinking at us.
这就是中子星。
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.
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.
生产或者中子平衡,还有这是一个中子平衡等式。
Production or neutron balance and this is a neutron balance equation.
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.
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.
