例句

It means that our measurement of the antiproton's mass relative to the electron is now almost as accurate as that of the proton.

這意味著，現在我們對反質子對電子的質量測量精度幾乎與測量正質子一樣。

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

接著，反原子會遇到一個強電場，把束縛松散的反原子里的反質子及正子給拆開。

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

舉例來說，一個反氫原子，由帶正電荷的正電子圍繞帶負電荷軌道運行的反質子組成。

The Tevatron continues to break records for luminosity, the number of high-energy proton-antiproton collisions it produces.

在加速器中，質子與反質子碰撞時產生的光強不斷被打破。

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

有些反質子的消滅會放出大量正子，進而產生能量為511keV的γ射線，兩者都可以偵測到。

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

就像正質子那樣的粒子，如果它與其反物質的配偶——反質子相遇，這兩個粒子就會在強大的爆炸中相互湮滅。

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

反氫原子是正電子（所謂正電子就是反物質的電子）圍繞著以反質子為核心，作軌道運行所形成。

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

反質子減速器里不斷飛出的反質子束可以逐漸加到阱里，這是TRAP所發明出來的堆疊過程。

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

根據自己的研究，比克福德預測其他的行星包括木星、土星、海王星和天王星也應該有類似的反質子帶。

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

在一級玻恩近似下，研究了在激光輔助的電子偶素-反質子碰撞中的反氫合成。

Thus, antiquark, antiproton, etc.

像反夸克，反質子等等。

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

狄喇克的理論還預言有一種質子的姐妹粒子，帶負電荷，叫做反質子。

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，一個質子用“p”表示，而一個反質子用“p”在它的頂端上加一條線表示。

Since 2000 this deceleration has been carried out by the Antiproton Decelerator at CERN.

從2000年開始，CERN的反質子減速器就在進行這樣的減速過程。
