antiprotons

To make cold antihydrogen, the experimenters must slow down the antiprotons to a temperature similar to that of the positrons.
要制作冷的反氢，实验者必须将反质子减缓到与正子相近的温度。
The antiprotons are then pushed into the same trap as the positrons and left to mingle for a second or so.
然后将反质子推入到装有正电子的容器中，用大约一秒钟的时间等待它们混合。
It has developed better techniques for cooling both positrons and antiprotons, which should allow it to trap more anti-atoms.
该小组已开发出冷却正电子和反质子的改进技术，通过应用这些技术应该能够捕获到更多的反原子。
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。
A chain of reactions, starting with a beam of laser-excited cesium atoms, transfers the positrons to the antiprotons to form antihydrogen.
一连串反应开始于以雷射光激发铯原子束，然后使正子移到反质子旁以形成反氢。
Coaxing hot and bothered antiprotons and positrons to couple is quite a task.
让处于高温与高速运动状态的反质子和正电子进行结合是一桩非常困难的工作。
The best concepts for antimatter propulsion require that the antiprotons be collected and isolated.
至于反物质推进，最好的想法是将反质子收集起来并实施隔离。
Pairs of protons and antiprotons are also directly produced in the cosmic ray collisions with the atmosphere.
宇宙射线撞击大气时，也会直接产生成对的质子和反质子。
To trap antiprotons, one would have to reverse the electric field, thus inverting the potential.
要抓住反质子，电场的方向必须反过来，使电位的高低与原来相反。
Physicists have long suspected that antiprotons must become trapped in a belt around Earth. Now they've found it.
长期以来物理学家认为一些反质子一定被捕获在地球的一个条带中。现在他们已经找到它了。
