1·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。
2·But some astronomers always suspected that the remaining antiprotons must become trapped by the Earth's magnetic field, forming an antiproton radiation belt.
但是一些天文学家一直怀疑，那些剩下的反质子一定被地球磁场捕获，形成一条反质子辐射带。
3·It means that our measurement of the antiproton's mass relative to the electron is now almost as accurate as that of the proton.
这意味着，现在我们对反质子对电子的质量测量精度几乎与测量正质子一样。
4·"This is a very satisfying result," Masaki Hori, a project leader in the antiproton collaboration, said in a statement.
研究反质子合作项目的负责人堀·正树在一份声明中说：“这是一个非常令人满意的结果。”
5·His research team discovered the antiproton.
他的研究组发现了反质子。
