如果这些中子被另一个不稳定的核捕获,它们也可以裂变,导致链式反应。
If these neutrons are captured by another unstable nucleus, they can fission as well, leading to a chain reaction.
最可信的竞争者是双中子星,或者一个中子星与一个黑洞。
(The most plausible competitors would be two neutron stars, or a black hole and a neutron star.).
他负责中子俘获在满足实验室:没有足够的中子和连锁反应会自行关闭;
He was in charge of neutron capture at the Met Lab: not enough neutrons, and the chain reaction would shut itself down;
那么,一个碳原子可能有6个中子,或7个中子,可能或8个中子-但它总是有6个质子。
So, a carbon atom might have six neutrons, or seven, or possibly eight- but it would always have six protons.
这是因为中子光谱仪实际上并不是用来探测水的,但它能够探测到氢。
That's because the neutron spectrometer is not actually intended for the detection of water, but it can detect hydrogen.
其他粒子探测器识别质子、中子和电子--构成原子甚至整个原子的粒子。
Other particle detectors identify protons, neutrons and electrons- the particles that make up atoms- or even entire atoms.
中子通常被认为是粒子,但也有类似于光的波状性质,这取决于它们的速度。
Neutrons are normally thought of as particles, but also have wave-like properties similar to light, depending on their speed.
因此,“以这种方式观测中子星有点像在太空中使用实验室研究核物理,”她补充道。
And so"observing neutron stars in this way is kind of like using a laboratory in space to study nuclear physics," she added.
在早期,它被认为其他六个核粒子将具有与质子相同的质量,但具有中性电荷:中子。
Early on it was thought the other six nuclear particles would have the same mass as protons butbe neutrally charged: neutrons.
不同形式的氢,或任何核,有相同数量的质子但不同数量的中子被称为同位素。
(Different forms of hydrogen, or any nucleus,having the same number of protons but different numbers of neutrons are called isotopes.).
这些中子进一步撞击另外3个铀原子并开始连锁反应,帮助获得大量热能。
These neutrons further strikes another 3 uranium atoms and starts up a chain reaction, helping in getting a great amount of thermal energy.
我们知道微透镜是由恒星,中子星或恒星质量黑洞引起的,“StevenRodney解释道。
We know that the microlensing was caused by either a star, a neutron star, or a stellar-mass black hole," explains Steven Rodney.
电子和中子等物质波为显微镜学带来突破,让我们可以「看」到原子的个体。
The use of matter waves such as electrons and neutrons have brought about breakthroughs in microscopy, allowing us to"see" individual atoms.
蟹状星云中心的中子星是一个巨大的原子核,关于曼哈顿的大小,一秒钟纺三十次。
The neutron star at the center of the Crab Nebula is an immense atomic nucleus, about the size of Manhattan, spinning thirty times a second.
此前的研究提出了一个关键线索:原子核通常需要快速吸收中子,这种现象被称为"r过程"。
Previous research suggested a key clue:atomic nuclei often needed to absorb neutrons rapidly, a phenomenon known as the“r-process” for short.
这些质子和中子的数量决定了原子是铁还是氧或氙,以及它是放射性的还是稳定的。
And the numbers of those protons and neutrons determine whether the atom is iron or oxygen or xenon, and whether it's radioactive or stable.
中子星发射X射线辐射,使NICER技术能够观察和记录关于其结构、动力学和能量学的信息。
X-ray radiation is emitted by the Neutron stars, which enables NICER technology to observe and record information about its structure, dynamics and energetics.
根据这个理论,两颗中子星的合并可以触发一个射流的释放,冲击周围的气体碎片。
In accordance with this theory, the merger of two neutron stars could trigger the release of a jet that shock-heats the surrounding gaseous debris.
来自合并中子星的引力波探测数据(GW170817)对解决这一难题做出了重要贡献。
The data from the detection of gravitational waves from merging neutron stars(GW170817) make an important contribution toward solving this puzzle.
这就是我们实际上可以开始区分测量中子寿命的两种不同实验方法的结果的地方,”Chang说。
That's where we can actually begin to discriminate between theresults from the two different experimental methods of measuring the neutron lifetime," Chang said.
X-ray and neutron imaging was coordinated by Heloisa Bordalo, a Brazilian researcher at the University of Copenhagen's Niels Bohr Institute in Denmark.
这就是我们实际上可以开始区分测量中子寿命的两种不同实验方法的结果的地方,”Chang说。
That's where we can actually begin to discriminate between theresults from the two different experimental methods of measuring the neutron lifetime,” Chang explains.
