例如,任何违反氢和反氢之间对称的期望会动摇物理学的核心。
For example, any violation of the expected symmetry between hydrogen and antihydrogen would rock physics to its core.
反氢和氢原子应该有相同的特性,例如发出光的频率一模一样。
Antihydrogen and hydrogen atoms should have the same properties, emitting the exact same frequencies of light, for example.
他们在春天说,他们希望产生一束反氢激光制造出原子光谱的初步测量器以便它能与常态的氢相比较。
They say that in the spring, they hope to train a laser on the antihydrogen to make a preliminary measurement of the atom's spectrum so that it can be compared to regular hydrogen.
cern物理学家和雅典娜成员RolfLandua博士说,“目睹反氢的制造是非常令人兴奋的。”
"It's very exciting to see the production of antihydrogen," said Dr. Rolf Landua, a CERN physicist and Athena member.
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.
现在,研究人员在自然物理杂志上发表的报告称,他们已经利用设计的装置将反氢子存在时间延续到了16分钟。 (在原子物理术语上相当于亿万年)。
Now, as they report in Nature Physics, the researchers have used their device to preserve anti-hydrogen for 16 minutes (aeons in atomic-physics terms).
在一封电子邮件通讯中,Atrap的导师,美国哈佛大学GeraldGabrielse博士,称反氢的产生为“重要的和挑战性的”里程碑,而他的团体也同样认为。
In ane-mail message, Atrap's leader, Dr. Gerald Gabrielse of Harvard, called the production of antihydrogen an "important and challenging" milestone, adding that his group had seen similar signals.
