Every time you had one more proton, you had another element.(每發(fā)現(xiàn)多一個質(zhì)子，就會多一種元素。)

The fission process would be controlled using neutrons produced by a linear accelerator's proton beam.(該裂變過程會利用直線加速器質(zhì)子束產(chǎn)生的中子加以控制。)

When a neutron inside an atom decays, it produces a proton, an electron, and a neutrino.(原子內(nèi)的一個中子衰變后會產(chǎn)生一個質(zhì)子、一個電子和一個中微子。)

The very small is a small fraction of a proton and the very large is the universe itself.(小到光子的，一個組成部分，大到宇宙的本體。)

If they exist, each string would be as thin as a proton, but incredibly dense.(如果宇宙弦存在，每根弦都像質(zhì)子一樣小，密度卻極大。)

Each proton (or neutron) has about two thousand times the mass of an electron.(每一個中子或者質(zhì)子的質(zhì)量都是一個電子的兩千倍。)

Proton exchange membrane fuel cells use a perfluorosulfonic solid polymer film as electrolyte.(質(zhì)子交換膜燃料電池采用全氟磺酸固體聚合物膜為電解質(zhì)。)

The advantage of hydrogen is its unrivalled simplicity: one electron circles a single proton.(氫的優(yōu)勢是其結(jié)構(gòu)非常簡單：一個電子環(huán)繞一個質(zhì)子。)

This is then fed into a complicated QED calculation to obtain the radius of the proton.(把這個測量值代入一個復(fù)雜的量子電動力學(xué)(QED)計(jì)算公式然后得到質(zhì)子的半徑。)

That’s a proton collision played on marimba.(這是木琴演奏的一段粒子碰撞的聲音。)
