antiprotons æntɪ'prəʊtɒn COCA⁹³⁸⁰⁹BNC⁸²⁵³⁰⁺¹⁰
基本例句
n.能反质子等于negative proton能负质子原型antiproton的复数 Lo and behold, these guys found28 antiprotons.
哎呦看看，这些家伙找到了28个反质子。 yeeyan
The best concepts for antimatter propulsion require that the antiprotons be collected and isolated.
至于反物质推进，最好的想法是将反质子收集起来并实施隔离。 yeeyan
The number of antiprotons needed, however, would exceed the amount in the newly discovered belt or even the much larger belt that may circle Saturn, Bickford says.
然而比克福德说，需要的反质子数量会超过反物质带中新发现的数量，甚至会超过大得多的、潜在的环木星反物质带中反质子的数量。 yeeyan
The antiprotons are then pushed into the same trap as the positrons and left to mingle for a second or so.
然后将反质子推入到装有正电子的容器中，用大约一秒钟的时间等待它们混合。 ecocn
The antiprotons in this scheme would be gathered into a vast fuel tank, a nearly weightless cloud hundreds of meters long surrounding the craft.
在这一计划中，反质子被收集起来装进一个巨大的燃料箱，该燃料箱实际上就是环绕在飞船周围长达几百米的无重量云团。 yeeyan
At the right moment, the antiprotons would mix with protons and annihilate them to produce highly energetic charged particles to propel the craft.
在合适的时刻，使反质子和质子混合，发生湮灭，产生高能带电粒子，推进飞船运行。 yeeyan
But some astronomers always suspected that the remaining antiprotons must become trapped by the Earth's magnetic field, forming an antiproton radiation belt.
但是一些天文学家一直怀疑，那些剩下的反质子一定被地球磁场捕获，形成一条反质子辐射带。 yeeyan
But this raises an interesting question: what happens to the antiprotons after they are created?
但是这提出了一个有趣的问题：这些反质子在诞生之后又怎样了？ yeeyan
In 2006, these guys launched a spacecraft called PAMELA into low Earth orbit, specifically to look for antiprotons in cosmic rays.
2006年，这些天体物理学家发射了一艘人造卫星，命名为 PAMELA，进入低地球轨道，专为寻找宇宙射线中的反质子。 yeeyan
Next, an electrical field is used to kick out any remaining positrons and antiprotons.
接着加上一个电场将所有未聚合的正电子和反质子排出这个容器。 ecocn
Now astrophysicists say they've finally discovered this long- fabled belt of antiprotons.
现在天体物理学家说，他们终于发现了这条长期存在于传说中的反质子带。 yeeyan
Physicists have long suspected that antiprotons must become trapped in a belt around Earth. Now they've found it.
长期以来物理学家认为一些反质子一定被捕获在地球的一个条带中。现在他们已经找到它了。 yeeyan
Saturn may produce the greatest number of antiprotons because of interactions between cosmic rays—energetic charged particles from space— and the planet's icy rings.
由于宇宙射线来自太空的高能带电粒子和土星冰冷的光环之间进行相互作用，土星上产生的反质子数量可能最多。 yeeyan
The belt, which extends from a few hundred to about2000 kilometers above Earth, “ constitutes the most abundant source of antiprotons in Earth's vicinity,” Bruno says.
“这条带在地球以上几百公里到大约2000公里处延伸着，构成了地球附近最为丰富的反质子储存库，”布鲁诺说。 yeeyan
This constitutes“ the most abundant source of antiprotons near the Earth”, say the PAMELA team.
这构成了“接近地球的最丰富的反质子源”， PAMELA团队说。 yeeyan
Unfortunately hadrons, such as protons and antiprotons, are made of smaller bits called quarks.
不幸的是，强子，比如质子和反质子，是由名为夸克的更小单元所组成的。 ecocn
Antiprotons are particles with the same mass as more familiar protons but with opposite charge.
反质子跟我们比较熟悉的质子质量相同，但是所携带的电荷相反。 yeeyan |
