Protons are made of much smaller components called quarks and gluons.

质子是由更小的夸克和胶子组成的。

Then there are neutrinos, W and Z bosons, the electron-like muon and tau particles, and gluons—which hold quarks together in groups.

然后还有中微子，W和Z波色子，类电子的μ粒子和τ粒子，还有胶子——它的作用是将夸克聚合成团。

But in its infancy, just microseconds after the Big Bang, the universe was so hot and dense these quarks and gluons existed freely and unbound.

但是在它的初始阶段，就是宇宙大爆炸后仅一微妙，宇宙是如此之热，致使夸克和胶子那时的存在是自由的和不受约束的。

A better agreement with the experimental data is obtained when it accounted for the contributions of anomalous gluons and orbital angle momentum.

同时把胶子的反常贡献和轨道角动量的贡献都考虑在内，计算结果与实验数据符合很好。
