常見例句Thus, antiquark, antiproton, etc. 像反夸克,反質(zhì)子等等。Dirac's theory also predicted a negatively charged sister for the proton, called the antiproton. 狄喇克的理論還預(yù)言有一種質(zhì)子的姐妹粒子,帶負(fù)電荷,叫做反質(zhì)子。Since 2000 this deceleration has been carried out by the Antiproton Decelerator at CERN. 從2000年開始,CERN的反質(zhì)子減速器就在進(jìn)行這樣的減速過程。Another team, ASACUSA, is studying exotic helium atoms in which one electron is replaced by an antiproton. 還有另外一個(gè)ASACUSA團(tuán)隊(duì),則是研究一種奇特的氦原子(反質(zhì)子取代了其中一個(gè)電子)。That means, in average, there is a extra proton or electron (antiproton) in 19100 neutrons. 也就是說,平均在19100個(gè)中子當(dāng)中,要夾帶一個(gè)過剩質(zhì)子或電子(反質(zhì)子)。For example, a proton is denoted with a "p", and an antiproton is denoted by a "p" with a line over its top . 舉例來說,一個(gè)質(zhì)子用“p”表示,而一個(gè)反質(zhì)子用“p”在它的頂端上加一條線表示。 返回 antiproton
