Next the antiatoms encounter a strong electric field that strips apart the antiproton and positron of the weakly bound antiatoms .

接著，反原子会遇到一个强电场，把束缚松散的反原子里的反质子及正子给拆开。

An atom of antihydrogen, for instance, is composed of a negatively-charged antiproton being orbited by a positively-charged positron.

举例来说，一个反氢原子，由带正电荷的正电子围绕带负电荷轨道运行的反质子组成。

在加速器中，质子与反质子碰撞时产生的光强不断被打破。

Some antiproton annihilations produce a shower of positrons, which in turn produce 511-keV gamma rays, two of which may be detected.

有些反质子的消灭会放出大量正子，进而产生能量为511keV的γ射线，两者都可以侦测到。

When a particle, such as a proton, meets with its antimatter partner, the antiproton, the two annihilate each other in a powerful explosion.

就像正质子那样的粒子，如果它与其反物质的配偶——反质子相遇，这两个粒子就会在强大的爆炸中相互湮灭。

The antihydrogen atoms are composed of a positron (an antimatter electron) orbiting an antiproton nucleus.

反氢原子是正电子（所谓正电子就是反物质的电子）围绕着以反质子为核心，作轨道运行所形成。

Successive bunches of antiprotons from the Antiproton Decelerator can be added to the trap, a process invented by TRAP called stacking.

反质子减速器里不断飞出的反质子束可以逐渐加到阱里，这是TRAP所发明出来的堆叠过程。

Bickford's own research predicts that other planets, including Jupiter, Saturn, Neptune, and Uranus, should have similar antiproton belts.

根据自己的研究，比克福德预测其他的行星包括木星、土星、海王星和天王星也应该有类似的反质子带。

Antihydrogen formation in the laser-assisted positronium -antiproton collision is investigated in the first Born approximation.

在一级玻恩近似下，研究了在激光辅助的电子偶素-反质子碰撞中的反氢合成。

Thus, antiquark, antiproton, etc.

像反夸克，反质子等等。

Dirac's theory also predicted a negatively charged sister for the proton , called the antiproton .

狄喇克的理论还预言有一种质子的姐妹粒子，带负电荷，叫做反质子。

For example, a proton is denoted with a "p" , and an antiproton is denoted by a "p" with a line over its top .

举例来说，一个质子用“p”表示，而一个反质子用“p”在它的顶端上加一条线表示。
