Scientists at CERN first produced antimatter in 1996 in an experiment that created antihydrogen.

欧洲核研究组织的科学家1996年在一次制造反的实验中首次制造出了反物质。

Last year ALPHA used a magnetic trap to hold on to antihydrogen atoms for a record 16 minutes.

去年ALPHA成功地使用磁阱，创纪录地令反存活长达16分钟之久。

He said that the research ruled out that gravity pushes antihydrogen away from the center of the Earth.

他说，这项研究排除了重力将反推离地球中心的可能性。

Later, thanks to advanced technologies, physicists were able to obtain not just antiparticles, but whole anti-atoms, anti helium, and antihydrogen.

后来，由先进的技术，物理学家不仅能得到反粒，而且能得到整个反、反氦和反。

During the experiment, researchers said the antihydrogen particles were moving around at a speed of about 100 meters a second.

在实验中，研究人，反粒的移动速度约为每秒100米。

Measuring the light spectrum of antihydrogen is a key part of solving that mystery.

测量反的光谱是解开这个谜团的关键部分。

And a great way to test that idea is by comparing the light coming from hydrogen and antihydrogen.

测试这个想法的一个好方法是比较来自和反的光。

But what they found was that the antihydrogen emitted the exact same spectrum of light as hydrogen.

但他们发现，反分发出的光谱与分完全相同。

So, in 2011, antihydrogen lasted as long as 1,000 seconds and in 2014, eighty anti hydrogen atoms were created for the purpose of a detailed study.

因此，在2011年，反持续了一千秒，而在2014年，为了一项详细的研究，八十个反被创造出来。

Working out of the CERN lab in Switzerland, these researchers figured out how to capture about 14 antihydrogen atoms within a 15-minute cycle.

在瑞士 CERN 实验室工作的这些研究人想出了如何在 15 分钟的周期内捕获大约 14 个反。

Previous research had only managed to capture about 1.2 antihydrogen atoms in a cycle, so the team had a lot more to work with.

之前的研究只能在一个循环中捕获大约 1.2 个反，因此该团队还有更多工作要做。

And if antimatter really is an exact mirror image of matter, then the positrons in antihydrogen should give off the exact same spectrum as the electrons in plain old regular hydrogen.

如果反物质真的是物质的精确镜像，那么反中的正电应该发出与普通中的电完全相同的光谱。

And in a paper published this week in the journal Nature, an international team of more than 50 researchers announced that they’d detected the spectrum of light coming from the antimatter form of a hydrogen atom, aka antihydrogen.

在本周发在《自然》杂志上的一篇论文中，一个由 50 多名研究人组成的国际团队宣布， 他们检测到了来自反物质形式（即反）的光谱。
