antimatter
意味: Matter composed of antiparticles, which have the same mass as their corresponding normal-matter particles but opposite charge and quantum properties. When matter and antimatter meet, they annihilate each other, releasing energy.
Antimatter occupies a unique position at the intersection of cutting-edge physics and science fiction. In particle physics, the asymmetry between matter and antimatter in the universe — why there is so much more matter — remains one of the greatest unsolved problems. CERN has successfully produced and trapped small quantities of antihydrogen. In popular culture, antimatter features prominently as a plot device in science fiction, from Star Trek to Dan Brown's Angels and Demons. The term collocates with particle, annihilation, trap, and propulsion.
例文
- CERN physicists have succeeded in trapping atoms of antimatter for long enough to study their fundamental properties. 欧洲核子研究中心的物理学家成功俘获了反物质原子,持续时间足以研究其基本性质。Los físicos del CERN han logrado atrapar átomos de antimateria el tiempo suficiente para estudiar sus propiedades fundamentales.CERNの物理学者たちは、反物質の原子を基本的性質を研究するのに十分な時間捕獲することに成功した。CERN의 물리학자들은 반물질 원자를 기본 성질을 연구할 수 있을 만큼 충분한 시간 동안 포획하는 데 성공했다.
- The annihilation of matter and antimatter produces energy with an efficiency far exceeding any chemical or nuclear reaction. 物质与反物质的湮灭所产生的能量效率远远超过任何化学反应或核反应。La aniquilación de materia y antimateria produce energía con una eficiencia que supera con creces la de cualquier reacción química o nuclear.物質と反物質の消滅は、あらゆる化学反応や核反応をはるかに上回る効率でエネルギーを生み出す。물질과 반물질의 소멸은 어떠한 화학 반응이나 핵반응을 훨씬 능가하는 효율로 에너지를 생성한다.
- The observed asymmetry between matter and antimatter in the universe remains one of the deepest puzzles in cosmology. 宇宙中观测到的物质与反物质之间的不对称性,仍然是宇宙学中最深刻的谜题之一。La asimetría observada entre materia y antimateria en el universo sigue siendo uno de los enigmas más profundos de la cosmología.宇宙における物質と反物質の間に観測される非対称性は、宇宙論における最も深い謎の一つであり続けている。우주에서 관측되는 물질과 반물질 사이의 비대칭성은 우주론에서 가장 심오한 수수께끼 중 하나로 남아 있다.

起源と歴史
From Greek anti- (opposite) + matter (from Latin materia, substance). The concept was first theorised by Paul Dirac in 1928, and the positron (the antiparticle of the electron) was discovered by Carl Anderson in 1932.
