光子没有质量——它们是没有重量的。

Photons have no mass – they are weightless.

《柯林斯英汉双解大词典》

一些粒子，犹如光子，本身很轻而只是光，能够挤过粘粘的希格斯场却没有获得质量。

Some particles, such as photons, which are weightless particles of light, are able to cut through the sticky Higgs field without picking up mass.

此外，LPN的科学家们还表明，这种“光子分子”概念的应用能够改善纠缠光子对的纠缠质量。

Moreover, the LPN scientists have also shown that the use of this photonic molecule concept allows the quality of the entanglement of the emitted photon pairs to be improved.

If a photon which has no mass can behave as a particle, does it follow then an electron which has mass can behave as a wave? 1920.

如果一个没有质量的光子,能像粒子一样运动，那么它能像一个,没有质量的电子那样以波的形式运动吗。

And that's really neat to think about, because photons, of course, are massless particles, they have no mass, so it's neat to think about something that has no mass, but that actually does have a momentum.

而且那真的不容易想明白，因为光子，当然是无质量的粒子，它们没有质量，所以这个真的不容易想明白,一些物体没有质量，但是它们事实上确实有动量。

If a proton which has no mass can behave as a particle does it follow that an electron which has mass can behave as a wave?

如果一个没质量的光子能像粒子一样,具有质量的电子能否,表现得像波一样吗？
