antinucleon

Antiparticles are created elsewhere in the universe where there are high-energy particle collisions, such as in the center of our galaxy, but none have been detected that are residual from the Big Bang, as most normal matter is [1] (http://science.nasa.gov/headlines/y2000/ast29may_1m.htm). - 根据报告，中国也正在认真地研发和增强守备如核子洲际弹道飞弹和反卫星飞弹。
China is also investing heavily in and fielding improved nuclear intercontinental ballistic missiles and antisatellite missiles, according to the report.
