例句

To make cold antihydrogen, the experimenters must slow down the antiprotons to a temperature similar to that of the positrons.

要制作冷的反氢，实验者必须将反质子减缓到与正子相近的温度。

让处于高温与高速运动状态的反质子和正电子进行结合是一桩非常困难的工作。

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。

Pairs of protons and antiprotons are also directly produced in the cosmic ray collisions with the atmosphere.

To trap antiprotons, one would have to reverse the electric field, thus inverting the potential.

要抓住反质子，电场的方向必须反过来，使电位的高低与原来相反。

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。

The antineutrons escape the atmosphere and then decay into antiprotons at much higher altitudes.

反中子逃离大气，然后在高得多的区域衰变为反质子。

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。

A small number of antiprotons constantly sleet down from space among cosmic rays.

而少量的反质子则是不断伴随著宇宙射线从太空洒落地球。

After a collection period, these antiprotons are released and detected by their annihilations on the nearby walls.

收集一段时间后，把这些反质子释放出去，让它们与邻近的墙碰撞、消灭，并加以侦测。

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。

Producing enough antiprotons to bend the space-time continuum looks near impossible as far as our current technology goes.

要制造足够的反质子来弯曲时空连续性，以我们目前的技术是不可能的。

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。

Unfortunately hadrons, such as protons and antiprotons, are made of smaller bits called quarks.

不幸的是，诸如质子和反质子之类的这些强子，是由叫做夸克的更小粒子组成的。

机器每隔约100秒发送1个反质子脉冲进入到冷的氦气中。

This process produces, among other particles, a high-energy pulse of antiprotons.

这个过程可以产生高能量的反质子脉冲以及其他粒子。

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。
