The year 2002 heralded a breakthrough in antimatter research when the first low energy antihydrogen atoms were produced. Antimatter has inspired both science and fiction writers for many years, but detailed studies have until now eluded science. Antimatter is notoriously difficult to study as it does not readily occur in nature, even though our current understanding of the laws of physics have us expecting that it should make up half of the universe. The pursuit of cold antihydrogen is driven by a desire to solve this profound mystery. This paper will motivate the current effort to make cold antihydrogen, explain how antihydrogen is currently made, and how and why we are attempting to trap it. It will also discuss what kind of measurements are planned to gain new insights into the unexplained asymmetry between matter and antimatter in the universe.
2002 年，当第一批低能量反氢原子被制造出来时，反物质研究取得了突破。多年来，反物质激发了科学和科幻作家的想象力，但直到现在，科学仍未能详细研究它。反物质极难研究，因为它在自然界中不易出现，尽管我们目前对物理定律的理解预计它应该构成宇宙的一半。追求冷反氢是为了解决这个深刻的谜团。本文将激发目前制造冷反氢的努力，解释如何制造反氢，以及我们为什么试图捕获它。它还将讨论计划进行哪些测量，以深入了解宇宙中物质和反物质之间无法解释的不对称性。
