该小组已开发出冷却正电子和反质子的改进技术，通过应用这些技术应该能够捕获到更多的反原子。
It has developed better techniques for cooling both positrons and antiprotons, which should allow it to trap more anti-atoms.
然后研究人员推动这个冷却的云斑，并进一步把反质子压缩，以致可以用一个相似大小的中子云来与它相重叠，就在那时，两个粒子（反质子和中子）成对地形成了反氢原子。
Then the researchers nudged this cloud of cold, compressed antiprotons so it overlapped with a like-size positron cloud, where the two particles mated to form antihydrogen.
几十年来，欧洲核子研究中心和其他地方的物理学家一直在想方设法克服反氢原子的这些局限。反氢原子由一个正电子与一个反质子构成，正电子绕反质子运行。
For decades, physicists at CERN and elsewhere have been trying to overcome these limitations with antihydrogen, which consists of a single positron orbiting a single antiproton.
为了要建立反氢原子，并且要使它不至于马上湮灭，反氢激光物理装置的研究团队把反质子冷却，并把它们压缩成火柴棍大小的云斑。
To create antihydrogen and keep it from immediately annihilating, the ALPHA team cooled antiprotons and compressed them into a matchstick-size cloud.
研究小组证实，1000万个反质子和7亿个正电子共形成38个稳定的反氢原子，每一个的存在时间只有短短十分之二秒左右。
Theteam proved that among their 10 million antiprotons and 700 million positrons, 38 stable atoms of antihydrogen were formed, lasting about two tenths of asecond each.
反氢原子是正电子(所谓正电子就是反物质的电子)围绕着以反质子为核心，作轨道运行所形成。
The antihydrogen atoms are composed of a positron (an antimatter electron) orbiting an antiproton nucleus.
在扭曲波冲量近似下，讨论中能区反质子与原子核非弹性散射的微分截面和极化度。
In the framework of the distorted wave approximation, we discuss the differential cross section and polarization of antiproton-nucleus inelastic scatterings at intermediate energies.
在大多数的反质子很快地同正质子相互湮灭的同时，数量很少的反质子由于它们同氦相结合形成为混合原子而幸存下来。此种混合原子含有着物质和反物质，是一种带有反质子的氦。
While most of the antiprotons quickly annihilate with regular matter, a tiny number survive by combining with helium to form hybrid atoms that contain matter and antimatter — antiprotonic helium.
